The quality of coking coal is vital in steelmaking, impacting final product quality and process efficiency. Conventional forecasting methods often rely on empirical models and expert judgment, which may lack accuracy and scalability. Previous research has explored various methods for forecasting coking coal quality parameters, yet these conventional methods frequently fall short in terms of accuracy and adaptability to different mining conditions. Existing forecasting techniques for coking coal quality are limited in their precision and scalability, necessitating the development of more accurate and efficient methods. This study aims to enhance the accuracy and efficiency of forecasting coking coal quality parameters by employing neural networks and artificial intelligence algorithms, specifically in the context of Knurow and Szczyglowice mines. The research involves gathering historical data on various coking coal quality parameters, including a proximate and ultimate analysis, to train and test neural network models using the Group Method of Data Handling (GMDH). Real-world data from Knurow and Szczyglowice mines’ coal production facilities form the basis of this case study. The integration of neural networks and artificial intelligence techniques significantly improves the accuracy of predicting key quality parameters such as ash content, sulfur content, volatile matter, and calorific value. This study also examines the impact of these quality indicators on operational costs and highlights the importance of final indicators like the Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) in expanding industrial reserve concepts. Model performance is evaluated using metrics such as mean absolute error (MAE), root mean square error (RMSE), and coefficient of determination (R2). The findings demonstrate the effectiveness of these advanced techniques in enhancing predictive modeling in the mining industry, optimizing production processes, and improving overall operational efficiency. Additionally, this research offers insights into the practical implementation of advanced analytics tools for predictive maintenance and decision-making support within the mining sector.

A mine cannot operate without environmental monitoring systems and basic mining machinery and equipment. In individual mines, these systems work in various configurations. Current information from these systems is visualized in the mine dispatch rooms. This article presents the basic structure of the visualization system, focusing on those most commonly used in our mines. It highlights that the diversity of monitoring systems used does not favor their unification and integration, aimed at providing the entrepreneur with essential data necessary for making crucial decisions related not only to the functioning of individual facilities within a company but, most importantly, the entire enterprise. The article introduces a new proprietary HADES visualization system program used in JSW SA mines. This program, named after the first microprocessor based dispatching system implemented in Polish mines several decades ago, enables the entrepreneur to make key decisions regarding the operation of the entire coal company and its individual facilities.

In recent years, cyberspace has become a new security environment,
which has introduced significant changes in both the practical, and legal
and organizational aspects of the operation of global security systems.
In this context, it is particularly important to understand the dynamics
of this environmental change (both in the provisions of the NIS 2 directive and the KSC Act). Building a legal system as a national  response to the opportunities and challenges related to its presence in  cyberspace was an extremely complex task. This results not only from  the pace of technological change, but also from the specificity of the  environment and its "interactivity". The trend in international law that  has emerged during COVID-19 and the current geopolitical situation is to treat organizations from the mining and energy sector as one of the  important actors in national and international relations.
The new regulations introduce and expand international cooperation
between individual entities and regulate security strategies and policies,
which should take into account the recommendations of the Ministry of
Climate and Environment, with particular emphasis on, among others,
ensuring the continuity of system operation, handling security incidents
and constantly increasing awareness of cybersecurity and cyber threats.
It should not be forgotten that threats in cyberspace represent a different
class of organizational challenges, largely similar to those posed by  other asymmetric threats such as terrorism. Their common feature is  that they require less hierarchical and more flexible solutions on state structures. Cybersecurity, both socially and technologically, with all its consequences, emerges as one of the most important concepts of the security paradigm at the national and international level.

Polish National Standards for underground excavation support design outline the deformational pressure model for assessing loads acting on the support systems of deep underground excavations. They distinguish two different rock mass models, highlighting the pivotal role of the critical longitudinal strain of the rock mass in appropriate model selection. A comparison between the design method given by Polish Standards and the widely recognized convergence-confinement method, consisting of a ground reaction curve (GRC), longitudinal displacement profile (LDP), and support characteristics curve (SCC), reveals the advantages of the latter in capturing the three-dimensional nature of underground excavations. The following study presents a method for establishing a GRC curve for the elasto-plasto-fractured rock mass model, featured in Polish Standards, demonstrating its applicability through analyses of a typical circular roadway under varying rock mass conditions. Practical implications are discussed, including the design of yielding steel arches as the primary support system and the calculation of safety factors for both the support system and the surrounding rock mass, considered as a natural support component. Overall, the study contributes to a deeper understanding of the actions of rock masses in the vicinity of excavations located at great depths. Furthermore, it provides practical insights for engineering applications.

This research is focused on examining the link between the abiotic conditions of coal mine heaps (specifically, the type of spontaneous vegetation) and their respiration rates. The hypothesis is that there is a significant correlation between the carbon content of the soil substrate and the respiration rate of the coal mine heap among the abiotic factors studied. The investigation was carried out on the mineral material found in coal mining heaps, which consisted of Carboniferous mineral rock material. The fieldwork spanned the vegetation seasons from 2018 to 2022. Various physicochemical parameters of the substrate samples were analyzed, including soil organic carbon content, electrical conductivity (EC), pH, total nitrogen (TN), available forms of phosphorus (P 2 O 5) content, available magnesium (MgO) concentration, exchangeable cations (K + , Na +), and moisture. Soil respiration measurements were taken using the TARGAZ-1 analyzer. The amount of carbon dioxide released at the sites studied ranged from 0.00158 to 1.21462 [g CO 2 /m 2 /h]. It was found that the carbon content and all the environmental factors tested had a significant impact on soil respiration (p = 0.001), except total nitrogen (p = 0.893). The factors most strongly correlated with soil respiration were potassium (K), alkaline phosphatase, and SRL (soil respiration). Of the taxa analyzed, only the below-ground conditions provided by the vegetation communities dominated by Centaurea stoebe showed a significant correlation with SRL. Three dominant plant species influenced the development of below-ground conditions, leading to negative effects. On the other hand, the below-ground conditions associated with vegetation patches dominated by Daucus carota showed the strongest negative correlation.

The subject of the paper is the analysis of the relationship between spontaneous vegetation diversity and soil respiration in novel post-coal mine ecosystem. In the natural and semi-natural ecosystems, soil respiration process (Rs) is a crucial ecosystem function regulating terrestrial ecosystems' carbon cycle. Soil respiration depends on the quality and quantity of the soil organic matter (SOM), the soil microbes' activity, and root metabolism. The listed factors are directly related to the composition diversity of vegetation plant species (biochemistry). For many years, soil respiration parameters have been studied in natural and seminatural vegetation communities and ecosystems. However, there still need to be a greater understanding of the relationship between vegetation plant species diversity and soil respiration as a crucial ecosystem function. Plant species diversity has to be analysed through both the taxonomic diversity and the functional diversity. These approaches reflect the composition, structure, and function of plant species communities. We hypothesise that the diversity of the spontaneous vegetation species composition shapes the amount of soil respiration in a post-coal mine novel ecosystem. The soil respiration differs significantly along the vegetational types driven by habitat gradients and is significantly higher in highly functional richness and dispersion vegetation patches. Contrary to our expectation, soil respiration was the highest in the less diverse vegetation types-both taxonomical and functional evenness were non-significant factors. Only functional dispersion is weakly negative correlated with soil respiration level (SRL).

Wetlands represent a small proportion of all habitats. Still, they are very important features within the landscape, particularly in the ecosystem mosaic. They are composed of many specifically adapted organisms. Wetlands spontaneously establish and provide a significant source of heterogeneity and diversity in an urban-industrial landscape. Most of Earth's wetlands are at risk or have disappeared due to human activity. Apart from natural wetlands, unique anthropogenic wetlands are observed in southern Poland. The aim of study was to assess and analyze the water quality and the spontaneous wetland vegetation which has developed on anthropogenic wetland habitats. The study was conducted on the spontaneous wetland vegetation developed in habitats that emerged due to mineral excavation activities of quarries in the Silesia Upland and Krakow-Częstochowa Upland. The research subjects were wetlands that provide special water chemistry conditions for developing the peat bog vegetation. Water sampling and analyses, vegetation recording, and vegetation numerical analyses were conducted on studied wetlands. The results of a study conducted on flooded post-excavation sites revealed that diverse wetland spontaneous vegetation colonized such habitats. This research showed that anthropogenic wetlands can provide habitats for the development of outstanding biodiversity and form a refuge for calcareous plant species and the subsequently assembled rare peat bog vegetation. The high moisture and the increased presence of magnesium and calcium ions are developing in some sites of the post-mineral excavations. Such habitat conditions in anthropogenic wetlands enhance the occurrence of rare calciphilous species. Maintaining the relevant water conditions is crucial for the protection of these sites. The study presented that, quite frequently, the human-induced transformation results in establishing habitats that provide conditions for refuge organisms, mostly plants crucial for conservation perspective, particularly in the urban-industrial landscape. The additional importance of this study is related to the fact that the area of wetlands decreased. Therefore such anthropogenic wetlands should be integrated into urban planning and industrial site management to enhance biodiversity conservation.

This paper presents some of the results of the project undertaken in JSW SA, which aim was to create a three-dimensional model of the deposits that make up the company and schedule company's production. The assessment of the quantity of coals without analysis of qualitative data, i.e. physicochemical parameters, coking parameters, and optical petrographic analysis is not suitable for obtaining commercial contractors. To obtain information on the quality of the coal seam, the geological service of the mine takes coal samples. In the stratigraphic model and quality model, dedicated interpolators are used for interpolation and extrapolation. In the seam quality model, the most optimized interpolators are Inverse and Height. Modelled parameters such as volatile parts content and random vitrinite reflectivity were analysed in detail. The Height interpolator looks for both a random and a linear dependency. It extracts random changes locally while searching for linear dependencies and extrapolates them to a deposit area that does not have qualitative data. There is a risk of extrapolating a given value to infinity. Nevertheless, the amount of data and the area modelled allows you to close its scope at an acceptable level. A separate POLYGON interpolator based on mxl express surfaces was created to map coal type range. It uses interpolated quality parameters at a given location, generating a range of a particular type of coal. Setting the trend of variability makes it possible to predict higher coal types in deeper, unrecognized batches of deposits according to documented variability in parameters.

Biomass, primarily derived from photosynthesizing plants harnessing solar energy, is crucial for ecosystem functioning and diverse services. This study delves into the unique ecosystem of coal mine heaps, exploring unexpected relations between abiotic factors and biomass in spontaneous vegetation. Biomass quantity and quality are influenced by factors like plant photosynthesis efficiency, necessitating an understanding of dynamics on post-mining sites. Our investigation focuses on diverse spontaneous vegetation on coal mine heaps, analyzing abiotic conditions such as soil texture, water holding capacity, pH, electrical conductivity, nitrogen, carbon, magnesium, sodium, and acidity. Contrary to our hypothesis, nitrogen content negatively correlates with soil total nitrogen, carbon, and water holding capacity. Dominant plant species' biomass, however, positively correlates with available phosphorus, pH, calcium, and sodium. These unexpected relationships highlight biomass dynamics complexity in novel ecosystems on coal mine heaps, stressing the need to consider spontaneous vegetation biomass as a valuable resource and ecosystem service in urban-industry landscapes. Findings expand scientific inquiry and have practical implications for post-industrial area reclamation. Understanding biomass potential in identified vegetation types provides insights into biomass character on coal mine heaps, crucial for maximizing spontaneous vegetation potential and transforming post-industrial landscape reclamation approaches.

The paper defines the principles of classifying hard coal deposits according to their thickness. For each minerał presented is the status of resources and reserves broken down per deposit width, and indicated the contribution of seams up to 1.5 m thick to the total production. Technology development directions in the aspect of thin deposit mining in Poland are outlined. The need for changing the role of thin deposits in the overall production structure is indicated. The problem of thin coal seam extraction is a real problem of the world mining, because such coal reserves account for a substantial share of many countries’ resources bases. There are many countries, which exploited only reserves of average and thick seams. Also, some countries mined only thin and rather thin coal seams. Recently this problem hasn’t been a global issue. Now, many countries increase mining of thin coal seams due to economic reasons; development of new techniques and technologies; also due to the exhaustion of the reserves occurring in convenient geological conditions. “Sustainable Development”, defmed for the first time in 1987 in „Our common futurę”, a report compiled by the UN Environment and Development Committee, is a term, which has recently made a remarkable career in scientific circles - and indeed among the broad public as well. Sustainable development was defined in the report as a process aiming at meeting the development needs of the present generation in a way making it possible for the futurę generations to meet theirs. At the same time, due to the multiplicity of factors, which may influence the environment, three main areas on which to focus when designing an effective sustainable development strategy were defined.

The technology of transportation and storage of gas in a gas-hydrated form under atmospheric pressure and slight cooling – the maximum cooled gas-hydrated blocks of a large size covered with a layer of ice are offered. Large blocks form from pre-cooled mixture of crushed and the granulated mass of gas hydrate. The technology of forced preservation gas hydrates with ice layer under atmospheric pressure has developed to increase it stability. The dependence in dimensionless magnitudes, which describes the correlation-regressive relationship between the temperature of the surface and the center gas hydrate block under its forced preservation, had proposed to facilitate the use of research results. Technology preservation of gas hydrate blocks with the ice layer under atmospheric pressure (at the expense of the gas hydrates energy) has designed to improve their stability. Gas hydrated blocks, thus formed, can are stored and transported during a long time in converted vehicles without further cooling. The high stability of gas hydrate blocks allows to distributed in time (and geographically) the most energy expenditure operations – production and dissociation of gas hydrate. The proposed technical and technological solutions significantly reduce the level of energy and capital costs and, as a result, increase the competitiveness of the stages NGH technology (production, transportation, storage, regasification).

Działalność podziemnych zakładów górniczych naznaczona jest wysoką niepewnością i szeregiem uciążliwości, które decydują o wysokim poziomie ryzyka operacyjnego i zawodowego. By jemu przeciwdziałać oraz ograniczyć możliwości błędnej oceny sytuacji przez osoby nadzoru, dyspozytornie kopalniane, począwszy od lal siedemdziesiątych ubiegłego wieku wyposaża się w liczne systemy telekomunikacyjne, monitoringu i telemetrii. Zasadniczo istnienie owych systemów ma na celu dostarczenie aktualnej i użytecznej decyzyjnie informacji na temat środowiska realizowanej działalności parametrów bezpieczeństwa, stanu maszyn i urządzeń, przebiegu produkcji ora/ procesów im towarzyszących. Niekorzystna dla branży dynamika zmian cen na rynku surowców energetycznych uwidacznia nową kategorię zagrożeń związanych bezpośrednio z otoczeniem rynkowym. Analogicznie jak w przypadku systemów dyspozytorskich obliguje to przedsiębiorstwa górnicze do wdrożenia adekwatnych narzędzi i mechanizmów wsparcia, ograniczających ryzyko niepowodzeń w ujęciu stricte ekonomicznym. W tym celu konieczna jest budów a odpowiedniego systemu informacyjnego, stanowiącego pomost pomiędzy płaszczyzną rynku a strategicznymi, taktycznymi i operacyjnymi mechanizmami działania przedsiębiorstwa. Opracowanie rozwiązania realizującego wymierne wsparcie procesów zarządzania produkcją w sposób stanowiący swoistą odpowiedź na rosnące wymagania ze strony rynku to jednak zadanie trudne i bardzo złożone. Naturalna bariera związana z warunkami funkcjonowania kopalń podziemnych prowadzi bowiem do odseparowania systemów informatyki gospodarczej od górniczej rzeczywistości. co w praktyce skutkować może ograniczeniem ich roli i ogólnej przydatności. W niniejszym artykule za szkielet systemu zarządzania produkcja przyjęto rozwiązania klasy MES (ang. Manufactiiring Execution System), stanowiące zgodnie z architekturą PERA lany. Purdue Enterprise Reference Architecture) ogniwo pośrednie pomiędzy systemami klasy SCADA (ang. Supervisory Control And Data Acquisition) i ERP (ang. Enterprise Resource Planning). Jak starano się dowieść, istnienie tego połączenia w naturalny sposób przeciwdziała zjawisku separacji systemów informatyki gospodarczej od szybko zmieniających się realiów działalności górniczej. W tym aspekcie, przedstawiono propozycję architektury systemu, wskazano jego podstawowe funkcjonalności oraz grupy dostępnych na rynku rozwiązań informatycznych, których umiejętne wdrożenie prowadzić powinno do wykształcenia efektywnych, skutecznych i trwałych rozwiązań w zakresie zarządzania produkcją. Zagadnienie to zaprezentowane zostało z perspektywy przedsiębiorstwa górniczego, które w sytuacji wysokiej podaży konkurencyjnych produktów- informatycznych koncentrować powinno uwagę na opracowaniu i wdrożeniu spójnej i przemyślanej wizji systemu wsparcia produkcji, w sposób Świadomy dobierając narzędzia zgodnie z własnymi potrzebami, wymaganiami otoczenia oraz możliwościami finansowymi.

The research work results, presented in the article, describe a system concerning the management of a production line in the aspect of stabilization and improvement of the run-of-mine quality and maximization of economic effects. Basing on the geological deposit model, the authors concentrated on designing mining operations and on planning production parameters. Special attention was paid to a development of the mine workings design module, the mining operations scheduling module, the module for mixing and optimization from the quality point of view as well as the module for mining operations revenues and forecasts of costs. Forecasting the production quality, planning and integration of mining processes with coal preparation processes and sales are discussed in detail. The article is ended with some recommendations of general character, including quality management at the stage of mining and production planning, quality monitoring at the stage of coal mining, and its preparation.

This publication delves into geomechanical processes encountered during sequential longwall mining of coal seams, with a unique focus on reusing the conveyor track of the prior longwall as the ventilation pathway for the subsequent longwall. An in-depth geomechanical rationale is provided for the reuse of excavations within jointed rock formations. To ascertain the critical roles played by various support and protective elements at each distinct mining stage, a comprehensive analysis is performed using finite element techniques to delineate the three-dimensional stress-strain characteristics of the rock mass. Employing an innovative methodology integrating multifactorial analysis, contemporary structural identification algorithms, and a neuroheuristic approach for predictive mathematical modeling, an integral stability metric for reusable mining excavations is introduced. Specifically, this metric quantifies the relative preservation of the excavation's cross-sectional area following its connection to the second longwall. Furthermore, the study tackles the challenge of nonlinear optimization through the application of the generalized reduced gradient method (Frank-Wolfe), ultimately deriving the optimal combination of factors that maximizes the preservation of the crosssectional area for these reusable excavations.

Mathematical modelling of rock mass breaking using blasting has
been applied to obtain formulas for the calculation of crush zone
radii, intensive fragmentation, and crack formation around the
charging cavity in the structure, diameter of the charging cavity,
diameter of the charge itself, detonation characteristics of an
explosive, boundaries of the rock strength, rock mass jointing, and
mineral compression under the effect of rock pressure. The methods
have been developed to calculate parameters of drilling and blasting
operations (DBOs) while driving the mine workings based upon the
idea of the arrangement of blastholes in terms of areas they occupy
in a fore-breast as well as upon their location relative to break-off
outline. Stage one of the methods involves calculating and designing
burn cuts where a distance between blastholes is determined with the
help of a fragmentation zone radius. Stage two means calculation of
both specific and total explosion consumption per borehole bottom,
line of least resistance (LLR) for a borehole in terms of intensive
fragmentation, areas of borehole groups, borehole number, analytical
and actual distance between boreholes, actual charge amount per
borehole, and actual specific and the total explosive (E) consumption
per borehole bottom. The methods have been tested in the operating
ore mine while driving a mine working. Emulsion explosive (EE)
Ukrayinit-PP-2 (Україніт-ПП-2) has been applied. The developed
methods have been used to calculate DBOs parameters for the
explosive. Trial blasts demonstrated the good firing of a borehole
bottom and uniform ore fragmentation; a high coefficient of borehole
use has been supported.

Jastrzębska Spółka Węglowa is the largest producer of high-quality type 35 (hard) coking coal and the leading producer of coke in the European Union in terms of production volume. The Group's mining area is located in the Upper Silesian Coal Basin. Approximately 44% of the coal produced by the Group coke is processed by the Group into coke, which, next to iron ore, is the basic component of the input for steel production in steelworks, foundries, the non-ferrous metals industry, the chemical industry and the production of insulating materials.
In the years 2012–2016, as a result of falling prices of steel, coke and coal, the economic and financial situation of the JSW Capital Group deteriorated significantly. The effects of the declines that have been going on for several years were visible on the market in the form of, among others: low utilization of steel production capacity, suspension of mining in mines, or or closing or limiting the production capacity of coking plants.

System sterowania quasi-rentownością eksploatacji i produkcji koncentratów w KGHM Polska Miedź S.A. — Nawigator, funkcjonuje w świadomości pracowników miedziowego koncernu, od blisko 5 lat. W artykule używamy pojęcia quasi-rentowności, gdyż elementem rynku po stronie sprzedaży jest parametr zadaniowy — kosztowy, ustalany przez Zarząd. Okres ten można podzielić zasadniczo na trzy etapy: 1. Etap związany bezpośrednio z tworzeniem teoretycznego modelu systemu. 2. Etap obejmujący implementację teoretycznych założeń do dedykowanego narzędzia. 3. Etap związany z wdrożeniem i monitoringiem. W czasie tych 5 lat w wyniku prowadzonych badań i analiz zidentyfikowano i zweryfikowano poprawność wyliczania wielu wskaźników, zoptymalizowano procedury pozyskiwania danych oraz spopularyzowano w szerokim zakresie wśród dozoru górniczego wiedzę w dziedzinie kosztów prowadzonej działalności eksploatacyjnej. W okresie tym zebrano również praktyczne doświadczenia w zakresie występujących ograniczeń, tak po stronie infrastruktury organizacyjnej, jak i środowiska informatycznego. W efekcie podjęto prace nad jego dalszą rozbudową oraz implementacją do narzędzia informatycznego typu hurtownia danych. Podjęte działania doprowadzić mają do rozszerzenia zakresu prowadzonych analiz oraz objęcia funkcjonalnością systemu całego procesu technologicznego pozyskiwania metalu, począwszy od urobku w kopalni poprzez jego przerobienie i wzbogacenie aż po proces metalurgiczny w hucie.

Najwięksi światowi producenci rud metali od dawna rozumieją konieczność stosowania nowoczesnych narzędzi informatycznych i ich rolę w procesie górniczym. Wraz z rozwojem samego oprogramowania, jak również rosnącymi mocami obliczeniowymi komputerów, rola ta jeszcze się zwiększa. Dziś praktycznie w żadnym zakątku globu nie da się zrealizować dużego projektu górniczego bez wykorzystania pakietów oprogramowania jednego z dużych dostawców, do których należą firmy takie, jak: Gemcom Software, Maptek, Ventyx, MineSight, CAE Mining, Micromine i wielu innych. Większość z nich oferuje kompleksowe pakiety, wspomagające pracę geologów, górników, mierniczych górniczych i innych inżynierów od momentu rozpoczęcia wierceń przy poszukiwaniu kopaliny aż do rekultywacji i zamknięcia kopalni. Dywersyfikując podstawową działalność, część producentów wchodzi też na lukratywny rynek oprogramowania korporacyjnego dla górnictwa, stając się konkurentami takich firm, jak SAP czy IBM. W artykule zaprezentowano ofertę największych producentów oprogramowania do planowania produkcji w odkrywkowych i podziemnych kopalniach rud metali na wszystkich kontynentach.

The characteristic feature of a modern civilization is intensification of economic development and associated with it consumption of minerał resources. Fear as to their sufficiency is therefore quite understandable, particularly with respect to nonrenewable resources. The more so that the growth experienced by industrial production in the 20th century grew more than ten times and in the period after World War II consumption of minerał resources reached a level equal to their total production during the whole past history of mankind. The fear accompanies humankind from the dawn of history and is a result of the role minerał resources play in the development of a civilization. Considering the above, any projects focused on optimization of deposit extraction should be considered worthy of attention. One of them - in the opinion of the authors of this paper - is undoubtedly a project aimed at building a Computer system to aid decision-making in the process of preparing a deposit for extraction. The paper characterizes the basie assumptions underlying the framework of such a system and describes the key parameters of the implementation project currently under way at “Bogdanka” S.A. Coal Mine - for a number of years consistently the best-performing underground hard coal mine in Poland - in which the authors are involved.

Spoil tips are anthropomorphic terrain structures built out of leftover materials from
underground or open pit mining. Usually the term spoil tips refers to those build out
of unusable particles from coal exploration. As such they consist mostly of slate and
various types of sandstone or mudstone. But also include some amount of coal and,
what is more important, coal dust. Fires of spoil tips are dangerous to the environment and humans. They can cause degradation of air, and water qualities. Sometimes  degradation to the environment can be irreversible. The presented survey was done  in two stages. the first included creating a general terrain model. This was done with  the use of long range laser scanner. The second step was a more detailed analysis of  spatial and temperature conditions. Two measuring seasons ware performed. The first  included a survey made with a short range laser scanner and a hand-held inferred camera. The obtained point cloud was supplemented with temperature value with the use  of software and hardware provided by the authors. The visualization of 3D discreet  thermal model was done in Bentley MicrioStation. The second included a usage of  Z+F IMAGER 5010 laser scanner equipped with T-Cam Rev 1.0 thermal camera insole. A new and unique device that connects laser scanner with infrared camera. This  season also provide a point cloud with attached temperature value of measured points.
This article provides the description of those two methods including a comparison of
their effectiveness and costs. It also describes the heat conditions occurring on spoil
tip of Lubelski Węgiel „Bogdanka” S.A coal mine surveyed in December 2015.

In underground hard coal mines, one of the main sources of waste rock occurrence in the output is the phenomenon of roof slump. This phenomenon increases the contamination of the output with waste rock, which in turn increases the mine's operating costs. The exploitation of increasingly thinner seams, the use of plowing technology, the increasing speed of mining progress - all these factors related to the mining technology used significantly affect the cleanliness of mining the coal seam.
More detailed identification of the causes of increased contamination of excavated material with gangue and forecasting its amount at the stage of operation planning may allow the application of appropriate remedial measures, often before the start of operation.
The authors believe that monitoring the amount and sources of waste rock in mining walls and in the faces of drilled headings may constitute the basis for developing a method for predicting the yield of a mining plant.
The article presents methods of modeling roof rockfall, which is the result of the work of the Mineral Raw Materials Acquisition Team of the Polish Academy of Sciences and LW Bogdanka S.A.. In the future, the proposed methodology can be used to analyze the course of roof rockfall and calculate the roof rockfall mass, as well as calibrate the system for continuous measurement of the quality of excavated material in excavations. mining.

The article undertakes an attempt of a cross-sectional discussion of the situation in information technology's implementation in Polish mining sector. Addressing some of already implemented IT solutions, focused on determination of new directions for development of the industry, was treated as a separate issue. IT has a particular role lo play in the Polish mining industry. It is linked with a specific character of the mining industry, which operates on the basis of limited resources of the mineral 's deposit whose characteristic traits and parameters are often highly variable, and creation of a theoretical model of a deposit, allowing for its complete mathematical description, is often extremely difficult.
W artykule podjęto próbę przekrojowego omówienia stanu informatyzacji polskiego sektora wydobywczego. Jako odrębną kwestię potraktowano omówienie niektórych wdrożonych już rozwiązań informatycznych mających wytyczać nowe kierunki rozwoju branży. Informatyka w polskim górnictwie ma szczególną rolę do spełnienia. Jest ona związana ze specyfiką górnictwa, które działa w oparciu o ograniczone zasoby złoża kopaliny, którego cechy i parametry są często bardzo zmienne, a stworzenie teoretycznego modelu złoża, umożliwiającego jego pełny opis matematyczny, jest często niezwykle trudne.

Spoil tips are anthropogenic terrain structures built of leftover (coal) mining materials. They consist mostly of slate and sandstone or mudstone but also include coal and highly explosive coal dust. Coal soil tip fires cause an irreversible degradation to the environment. Government organizations notice the potential problem of spoil tip hazard and are looking for ways of fast monitoring of their temperature and inside structure. In order to test new monitoring methods an experimental was performed in the area of spoil tip of Lubelski Węgiel „Bogdanka” S.A. A survey consisted of creating a 3D discreet thermal model. This was done in order to look for potential fire areas. MASW (Multichannel analysis of surface wave) was done in order to find potential voids within the body of a tip. Existing data was digitalized and a 3D model of object’s outside and inside was produced. This article provides results of this survey and informs about advantages of such an approach.

Interest in Business Intelligence systems (BI) has for years been noticeable throughout the world. This is no different in Poland, although the scale of their deployment is extremely limited due to still small presence of IT solutions in the Polish mining industry. Visible demand relates to mining companies that have implemented ERP systems. The article presents the increasing interest in BI systems and provides examples of their implementation.
Zainteresowanie systemami Business Intelligence (BI) jest od lat zauważalne na całym świecie. Nie inaczej jest w Polsce, chociaż skala ich wdrożeń jest niezwykle ograniczona z racji jeszcze w dalszym ciągu niewielkiej obecności rozwiązań informatycznych w polskim górnictwie. Widoczne zapotrzebowanie dotyczy przedsiębiorstw górniczych, które wdrożyły systemy klasy ERP. W artykule przedstawiono rosnące zainteresowanie systemami BI i przykłady ich wdrożenia.

The paper outlines the evolution of production monitoring systems used in the Polish mining industry, focusing in particular on control systems. A concept to put together a mine production management decision-aid system utilizing IT solutions and production monitoring is discussed. The solution consists in integrating within a Production Reporting Center, proposed by the authors, series of data supplied from a monitored area and technological process visualization. The paper outlines the concept of creating a system integrating current control center solutions with a number of production systems utilized in mines, which encompass the most essential infrastructure of an underground mine. In future, control systems, apart from providing for communication, control and monitoring will have to incorporate most of the control functions, securing the safety and continuity of production and so becoming a basic part of a Manufacturing and Execution System (MES), ie. a computer system for monitoring, maintaining and controlling mine production (Krzystanek 2004 & Wojciechowsk 2004).

Rope guidance of the conveyances is a reliable and convenient way of guiding cages and skips in the mine shafts and it is used in numerous underground mines all over the world. However it is not popular in Polish coal mines. Most of the Polish copper and coal mines operate on multiple levels, which requires mine shafts and hoists to support more than one level. In such situation it is necessary to install some kind of chairing system on the levels, i.e. stiff guides in their vicinity. Conveyance’s movement through the stiff guides on the level requires its speed reduction, which in turn leads to lowering of the hoist’s effectiveness. To avoid such situation, retractable guidance system was introduced on the level 960 in the Leon IV shaft in Rydułtowy Coal Mine, Poland. This paper presents the idea of the retractable guidance system, as well as calculations and measurements carried out to prove that the system is safe and reliable.

On the example of experiences LW “Bogdanka” SA mine and employees of the Mineral and Energy Economy Research Institute of the Polish Academy of Sciences the describes the use for specialist computer software for scheduling of roadways drivage and longwall mining operations. It discusses their most important features and benefits as well as their co-operation with the model of the deposit. The use of modern IT tools for production scheduling is now a standard in many coal mines in the world and one can assumed that the Polish mining industry will also be heading in this direction.

W artykule na przykładzie doświadczeń kopalni LW „Bogdanka” SA oraz pracowników Instytutu Gospodarki Surowcami Mineralnym i Energią PAN opisano wykorzystanie specjalistycznych programów komputerowych do harmonogramowania robót chodnikowych i ścianowych. Omówiono ich najważniejsze cechy i zalety oraz ich współdziałanie z modelem złoża. Wykorzystanie nowoczesnych narzędzi informatycznych do harmonogramowania produkcji jest w tej chwili standardem w wielu kopalniach węgla na świecie i należy przypuszczać, że polski przemysł górniczy również będzie zmierzał w tym kierunku.

Knowledge of the characteristics of the rock mass, expressed in terms of the overall quality of rocks, including combinations of different geological parameters and their relative significance to the whole rock mass, plays an important role in the course of mining operation. With this information we select the technique of mining the deposit and try to protect the roof to minimize the roof fall. Unfortunately, the lithology of roof rocks is often so variable that it is difficult to exactly predict their behavior, especially when the rock mass is violated by exploitation. Currently, one of the most of characteristic unfavorable phenomena related to the roof’s properties accompanying the mining operation, in particular mining of thin coal seams is the roof fall. Its appearance in the winning generates additional costs and reduces the quality parameters of the commercial product. This phenomenon is particularly problematic in the case of plow exploitation, where part of the roof in mining excavations is exposed. The article presents a description of the methodology of conducting detailed studies of roof rock lithology of the coal seam in longwall headings and in the longwalls with the current progress of the longwall. As it is clear from the conducted research, forecasting the size of roof fall in the planning stage of the mining operation can be an important indication for the use of appropriate measures to minimize this phenomenon before commencing the longwall, which can significantly reduce the cost of the mining process. To predict the amount of roof fall of the by-seam rocks, block modeling was used, through which the amount of waste rock from the roof fall was successfully determined, which can contaminate the output in the analyzed mining area. The article presented ways of modeling roof fall of rocks which are the result of the works of the Department of Acquisition of Mineral Resources of the Polish Academy of Sciences and LW Bogdanka SA. In the future, the proposed methodology can be used for analysis of the roof fall, for calculating the mass of the roof fall and calibration of continuous system for measuring the quality of the winning in the mine workings.

Any newly created area includes human-created habitats such as the mineral material of post-coal mining spoil heaps undergoing natural colonization and ecosystem development during the succession processes of vegetation colonization. The study of the factors that influence the succession dynamics, and the mechanisms behind this, have a long history (including the species-area relationship or Arrhenius equation).
Nevertheless, the list of scientific questions is increasing. One of the significant issues in the study of these processes is the relationship between factors influencing the Biodiversity–Ecosystem Functioning (BEF) relationships. The main prerequisite is the relationships between the plant species' assemblage mechanisms including diversity and the variety of assembly rules concerning the environmental abiotic habitat processes and these properties are not straightforward. At the large scale, parameters such as age and area of the colonized sites are considered to be important.
These relationships are more complicated in newly established post-mineral excavation habitats where novel ecosystems are developing. Regardless of the degree of disturbances, vegetation re-establishes in such environments, as a result of spontaneous succession, by the colonization and establishment of the best-adapted organisms. In the habitats of post-coal mining spoil heaps with pure oligotrophic mineral conditions, the non-analogous, newly formed composition of flora, fauna, and saprophytes has been stated in many previous field studies. This study aimed to explore the biodiversity versus area size relationships, in particular, it investigated the species composition and diversity found in the development of the spontaneous vegetation formed during primary succession on mineral substrate habitats of postcoal mining spoil heaps of different area sizes. We tested the hypothesis: species diversity of the vegetation patches on coal mine spoil heaps becomes more diverse on larger sites over time. These results indicate that the area size of the spoil heap significantly affects the diversity of the vegetation. Regardless of which of the characteristics of the vegetation type (dominant species) is compared, the vegetation on the heaps differs depending on its area size.
Keywords:
species-area relationship, Arrhenius equation, spontaneous succession, biodiversity – ecosystem functioning, non-analogous species composition, novel ecosystems.

The operation of underground mining plants is characterized by high uncertainty and
a number of nuisances, which result in a high level of operational and professional risk.
In order to counteract this and to reduce the possibility of supervisors misjudging the
situation, mine control rooms have, since the 1970s, been equipped with numerous telecommunications, monitoring and telemetry systems.
In this article, MES (Manufacturing Execution System) solutions were adopted as the
framework of the production management system, which, in accordance with PERA (Purdue Enterprise Reference Architecture), is an intermediate link between SCADA (Supervisory Control And Data Acquisition) and ERP systems. (Enterprise Resource Planning). As sought to be proven, the existence of this connection naturally counteracts the phenomenon of separation of business IT systems from the rapidly changing realities of mining operations. In this aspect, a proposal for the architecture of Demand and Quality Driven Management System was presented, indicating its basic functionalities and groups of IT solutions available on the market, the skilful implementation of which should lead to the development of effective, efficient and sustainable production management solutions.
The creation of the first CZAD JSW 4.0 Centre for Advanced Data Analysis in the Polish mining industry, i.e. a centre for comprehensive, multidimensional analysis and interpretation of data coming from the Control and Measurement Instrumentation and Automation systems (PL: AKPiA) of mining machinery and equipment, was discussed in detail. This issue was presented from the perspective of a mining company which, in the situation of high supply of competitive IT products, should focus on developing and implementing a coherent and well-thought-out vision of a solution supporting the most important areas of quality management, production planning and scheduling, monitoring of production processes as well as commercial and logistics processes, responsible for increasing the efficiency of managing the exploitation of the deposit and the volume of supply of the highest quality commercial product.
Automation of mining plant production processes is one of the most promising solutions to the problem of safety and efficiency, but implementing advanced automation concepts requires that artificial intelligence and humans are able to share situational awareness.
Examining the impact and possibilities of distributed human-machine situational awareness in particularly hazardous zones is one of the main goals of implementing the idea of Smart Mine 4.0.

Typowy proces rozwoju każdej kopalni można ogólnie przedstawić w kilku następujących po sobie krokach: 1. Rozpoznanie złoża. 2. Stworzenie modelu złoża. 3. Opracowanie i wdrożenie planu eksploatacji (projektu zagospodarowania złoża i... more
Typowy proces rozwoju każdej kopalni można ogólnie przedstawić w kilku następujących po sobie krokach:
1. Rozpoznanie złoża.
2. Stworzenie modelu złoża.
3. Opracowanie i wdrożenie planu eksploatacji (projektu zagospodarowania złoża i planu ruchu).
4. Likwidacja zakładu górniczego, rekultywacja i zagospodarowanie terenu pogórniczego.
Warto wziąć pod uwagę, że kroki 1-3 wpływają na siebie. Tworząc model złoża, można dojść do wniosku, że w niektórych partiach jest ono niewystarczająco rozpoznane, w związku z czym konieczne jest wykonanie dodatkowych wierceń (powrót do kroku I).
Prowadząc eksploatację uzyskujemy na bieżąco dane geologiczne, które należy wprowadzić do opracowanego wcześniej modelu złoża. Uaktualniony model złoża może dać wskazówki na temat tego, w jaki sposób prowadzić przyszłe wyrobiska górnicze, aby uzyskać optymalny stopień wykorzystania złoża, uniknąć zagrożeń naturalnych itd.

Budowa zakładu górniczego zaliczana jest do projektów o wysokim stopniu ryzyka inwestycyjnego. Nie tylko dlatego, że czas od momentu wykonania pierwszego otworu poszukiwawczego do rozpoczęcia działalności operacyjnej inwestycji wynosi około kilkunastu lat ale również dlatego, że wymaga długoterminowego zabezpieczenia warunków finansowania działalności z akceptacją dużego ryzyka docelowej wielkości posiadanych zasobów geologicznych i eksploatacyjnych (mesured i proven według klasyfikacji JORC), które w' ciągu tak długiego okresu mogą ulec diametralnym zmianom. Wiąże się to bezpośrednio z koniecznością poszukiwań nowych rozwiązań w obszarze zarządzania produkcją, które muszą wykazywać szczególnie dużą elastycznością w procesach planistycznych i odpowiednio szybko reagować na zachowania rynku.
Procesy planistyczne w ostatnich kilku latach stały się wyzwaniem interdyscyplinarnym łączącym zagadnienia geologii, górnictwa i ekonomii. Powiązanie tych obszernych zagadnień przysparza przedsiębiorstwom branży wydobywczej wiele problemów. Ten kierunek działania jest jednak niezbędny, jeżeli chcą one być konkurencyjne na obecnym rynku surowców mineralnych, dotyczy to zarówno nowych, ale także realizowanych projektów górniczych.
Efektywna predykcja parametrów produkcji górniczej ma szczególne znaczenie w procesie optymalizacji czasoprzestrzennego sczerpywania zasobów w dostosowaniu do pożądanych parametrów handlowych produktu. Harmonogram produkcji obejmuje wszystkie produkcyjne cykle życia projektu górniczego, tzw. Life of Mine od rozpoczęcia prospekcji i rozpoznania złoża, aż do procesu likwidacji zakładu. Warunkiem wykonania właściwej prognozy parametrów produkcyjnych, zarówno ilościowej, jak i jakościowej, jest poprawnie przygotowany model geologiczny oraz zlokalizowanie wyrobisk górniczych w przestrzeni 3D. Nowoczesne narzędzia IT dają możliwość uzyskania ciągłej informacji, np. odnośnie do grubości pokładu czy wartości parametru jakościowego w wybranym punkcie wyrobiska. Jednak do obliczeń parametrów produkcyjnych wymagane jest uśrednienie tych wartości w arbitralnie wybranych przestrzeniach zależnych od wymaganego poziomu szczegółowości
W przypadku tradycyjnych metod harmonogramowania produkcji, wartości te uśredniane są w przestrzeniach o znacznych wymiarach, co prowadzi do dużych rozbieżności między planowaną a realizowaną produkcją. Oczywiście istnieje możliwości ograniczanie tych przestrzeni, ale jest to proces czasochłonny, dlatego z reguły nie jest stosowany. Rozwiązania informatyczne dedykowane dla przemysłu wydobywczego dają również możliwość budowania trwałych zależności pomiędzy zadaniami produkcyjnymi. Dzięki temu zmiana terminu wykonania zadania skutkuje przesunięciem w czasie grupy innych zadań z nim powiązanych. Ta funkcjonalność znacznie skraca czas modyfikacji harmonogramu, jak również niemal od razu po wprowadzeniu odbiorów wskazuje aktualny harmonogram. Ma to bezpośrednie przełożenie na skrócenie czas uzyskania informacji odnośnie do produkcji przez osoby kierownictwa.
Obecnie stosowane metody harmonogramowania produkcji typu one by one nie dają możliwości uzyskania w prosty sposób trwałych zależności pomiędzy zadaniami. Ich wykonanie wymuszałoby na projektancie tworzenie dodatkowych skomplikowanych formuł, skryptów bądź aplikacji, co skutkowałoby wydłużeniem czasu przygotowywania harmonogramów. Obecnie, ze względu na brak stosowania trwałych zależności między zadaniami, czas modyfikacji bądź aktualizacji harmonogramów produkcji jest niezadowalająco długi.
Początki narzędzi IT dla sektora górniczego sięgają lat 70. XX wieku. Rozwój technologii informacyjnej w ostatnich kilkudziesięciu latach spowodował, że obecnie oferowane produkty znacznie różnią się od pierwszych rozwiązań. Obecnie na rynku istnieje kilkanaście marek oferujących produkty wspierające procesy modelowania geologicznego i planowania produkcji.
Autorzy artykułu, w ramach swojej pracy badawczej, analizowali możliwości zastosowania rozwiązań informatycznych przy budowie długoterminowych planów produkcyjnych stanowiących filar strategii każdej, nowoczesnej, patrzącej w przyszłość spółki górniczej.

Effective implementation of new market strategies faces the mining enterprises with new challenges, which require precise assessment instruments of the carried out business to be met at the level of mines, preparation plants, coking plants, and steelworks. These instruments include deposit, technological, and economic parameters, which together with a safety margin, determining a percentage reserve level of each parameter, shape the profitability of undertaken projects. The paper presents the course and obtained implementation effects of a unique system for the production line management in the capital group of the Jastrzębska Spółka Węglowa (JSW) SA. The developed system allows optimizing the effectiveness of the production process in the system of one carried account within the entire mining group, which consists of mining plants together with preparation plants and coke plants. In particular, the paper raises the effectiveness issues of the system for deposit modeling and mining production scheduling in a multi-plant enterprise. The heuristic technical architecture of the JSW S.A. production line management system, presented in the paper, allows to analyse the production process profitability in a carried account system in the area of mines, preparation plants, and coking plants of the mining group of the biggest European coal producer for metallurgical purposes. The assumptions related to the construction of a system being in the future a basis for the realization of the Mine 4.0 idea are discussed.

The article presents the SOK Research Project idea, course and final results. The project was oriented onto an implementation of exclusive bolting in one of the Polish underground coal mines, realized with use of a multifunction Bolter Miner. Until starting that project the Jastrzębska Spółka Węglowa S.A. (Jastrzębska Coal Company J.S.C.) has been using different types of other supports (steel arches as gallery / roadway supports). Previous trials of implementing exclusive bolting in the Polish coal mines in the nineties of the XX century were not successful due to different reasons. In the case of the SOK Research Project, after having conducted detailed geological and mining analyses, a part of the Seam 401 in the Budryk Mine was chosen for tests of exclusive bolting with use of JOY 12CM30 Bolter Miner in the gallery drilling operations. Due to previous experience, gained in the process of exclusive bolting in the Upper Silesian Coal Basin conditions, special attention was paid to bolting designing as well as an installation and monitoring. As the SOK Research Project was the first trial in Poland of gallery drilling using exclusive bolting and Bolter Miner, so it was difficult to predict exact costs and final efficiency results. For all the project participants, i.e. the mining crew, engineers, managers and researchers it was an on-job training in the scope of new technology. The SOK Research Project enabled to gain a lot of new experience and knowledge, leading to guidelines and conclusions which can be useful in the following exclusive bolting implementations with Bolter Miner technology.

Effective implementation of new market strategies faces the mining enterprises with new challenges, which require precise assessment instruments of the carried out business to be met at the level of mines, preparation plants, coking plants, and steelworks. These instruments include deposit, technological, and economic parameters, which together with a safety margin, determining a percentage reserve level of each parameter, shape the profitability of undertaken projects. The paper raises the issues of designing an IT architecture of the system for deposit modelling as well as the mining production scheduling, implemented in the JSW S.A. The development and application of the system was important from the point of view of the overriding objective of the Quality Programme of the JSW Capital Group, that is increasing the effectiveness of deposit and commercial product quality management. The paper presents next the developed required specification of the technical architecture, necessary to implement systems as well as the required actions necessary to integrate with other IT systems of the JSW Group. The heuristic technical architecture of the JSW S.A. production line management system, presented in the paper, allows to analyse the production process profitability in a carried account system in the area of mines, preparation plants, and coking plants of the mining group of the biggest European coal producer for metallurgical purposes. The market of mineral raw materials, and in particular of hard coal, became very unpredictable recently. The situation of raw materials market becomes to be problematic for businessmen, who must very flexibly adapt their companies to variable market conditions in order to maintain viability of their mining projects.

The authors concentrated on some issues related to the sustainable development of the mining industry, i.e. on the management of fossil fuels deposits to achieve economic efficiency, environmental, as well as social acceptance. It should be borne in mind that Poland still belongs to the countries in which electric energy production and thermal energy production are based on hard coal and lignite. The research work results described in the article present efficiency assessment aspects in the case of different longwall technological systems in the LW Bogdanka. Advantages and disadvantages resulting from using shearer and plow systems are given. An impact of dilution in the run-of-mine on the coal quality is analyzed, and some recommendations emerging from this analysis are suggested. On the basis of the conducted in situ experiments, technical possibilities of reducing dirt are described. As an efficiency assessment is a multi-criterion process, so it requires continuous monitoring of production parameters. The article also contains an analysis of longwall systems in the aspect of dust control. An impact of mining, technical and technological parameters on generated dust amount, in particular in the case of a shearerequipped longwall face, is discussed. In the conclusions, it is highlighted that an efficient assessment process in the case of longwall systems is complicated as an impact of different factors should be taken into consideration. It is suggested to use the data integration platform based on the Service Oriented Architecture (SOA). Due to the SOA, any mistakes in the scope of the functionality of individual systems can be detected very quickly. Such an approach is fundamental for the realization of the TPM (Total Productive Maintenance), leading to the creation of the socalled Mine of Smart Solutions.

The monograph is dedicated to a wide range of recipients interested in the digital
transformation of traditional branches of economy into learning organizations, i.e. those that, in a systematic and active way, using their own experience and available information resources, optimize their business model in accordance with the industry 4.0 paradigm, maintaining competitiveness in the changing, dynamic market.
The digital revolution of the raw materials consortium described in the monograph explains and documents the digital transformation that took place in the JSW mines in the years 2016÷2020. The book covered processes related to underground computerization, radio communication, monitoring of occupational safety conditions, automation and the use of advanced data analytics to make management decisions. It presents the experience gained by entire research teams in the result of realizing strategic projects for nearly four years, documenting the greatest technological breakthrough in the Polish mining industry in years.
The DIGITAL TRANSFORMATION of Poland's key raw material consortium - extensively described on the pages of the monograph – on the one hand allowed for
the implementation of strategic efficiency programmes such as QUALITY and EFFICIENCY, but what is equally important, it allowed for the elimination of the huge technological debt with which Jastrzębska Spółka Węglowa S.A. has been dealing with it basically since its establishment in 1993 and in the subsequent years of its operation. This debt, growing year by year, strangled the technological innovativeness of the JSW S.A., especially in the years 2000÷2015, paralyzing the implementation of advanced IT projects and not recognizing the OT area at all, the implementation of which could have significantly improved the production monitoring and control processes in the JSW mines.
The book presents the Polish experience of entire teams of engineers: IT specialists,
automation specialists, miners, geologists and economists, transforming the traditional branch of the economy, which is mining, into a European raw material consortium with ambitions, showing, among others:
− how to build a management and supervision strategy over the production area of a modern raw materials company,
− how to design the integration and automation of entire production processes and innovative IT/OT solutions in the production and commercial cycle in the field of technical infrastructure, communications, applications supporting security areas and data processing,
− how to monitor the area of cybersecurity, security of systems and automation devices used in production,
− how to create planning for the desired future, based on the analysis of past experience and functioning in the present and future.
The systems for locating people and equipment, gasometric systems, monitoring of
methane drainage networks and seismic phenomena, described in the monograph, have a significant impact on ensuring the appropriate level of safety

Novel Ecosystem development in urban-industry areas as the prerequisite of modern economy is a thematically compact work on issues in the field of ecosystem functioning. The specificity of the reviewed work consists in applying the available knowledge and experience of researchers gained as a result of research conducted on natural and semi-natural habitats and ecosystems to the specific conditions of urban-industrial habitats. Characteristics and references to the Novel Ecosystem concept occupy an important place. This is crucial because more and more facts found during field studies prove that the processes taking place in the specific conditions of urban and industrial habitats differ from the previously known mechanisms of formation and functioning of natural and semi-natural ecosystems. The book presents an innovative approach to issues that have long been of interest to naturalists. The book presents how the processes and functioning of ecosystems, the relationship between abiotic and biotic parameters and colonization and development, association of living organisms, the formation of trophic chains, building biomass and ultimately fundamental and at the same time key decomposition processes in natural and semi-natural ecosystems are
generally known in specific aspects. The authors also indicate in which areas there are many books that present the available scientific knowledge, explain theories, concepts, principles, regarding the modern understanding of the ecosystem functioning in natural and semi-natural systems.
Most post-mining areas meet the criteria of novel ecosystems. These
proposals use the latest knowledge on the processes and functioning of
ecosystems in areas transformed by man (novel ecosystems). There are few published results of interdisciplinary research on the mechanisms of ecosystem functioning. There are even fewer research results available for specific postmining habitats. Therefore, it is not possible to provide ready-made rules of action, universal for all types of post-mining habitats and substrates. On the other hand, from the latest research of the world literature, it is known what certainly should not be done so as not to worsen the condition of the natural environment.
With the current state of knowledge, it is possible to propose specific actions for specific fragments using an individual site-specific approach to a specific type of terrain. Given the need to limit and counteract global changes, each type of habitat and developing ecosystem that can contribute to increasing the natural capital is valuable. It has been shown that in post-mining areas there are many valuable habitats and developing ecosystems with significant natural potential. Both these habitats and ecosystems, in addition to their natural values and potential, are also
a resource for the most important group of ecosystem services, supporting and  auxiliary services. Unfortunately, many records and statements indicate that people responsible for developing innovative solutions for managing the natural environment of post-mining areas have a very general and superficial orientation in important issues of the latest concepts, they use non-existent names of categories of ecosystem services. Therefore, to organize the basic concepts and present complex interdisciplinary issues as well as the current state of knowledge regarding the relationship between processes taking place in the natural environment, the following text has been prepared. The book consists of six parts.
The first part of the book is a basic introduction to understanding
the principles of ecosystem functioning. Concepts and definitions, essential concepts, connections between the basic elements of the ecosystem. The structure of an ecosystem and the structural relationships between the processes that underpin life on earth and most natural resources.
In the second part, abiotic and biotic parameters are characterized, which
determine the structure of the ecosystem, processes and functioning. It is
described in detail how dynamic changes caused by human activity, and carried out as habitat conditions, affect the course of ecosystem processes. With regard to habitats created as a result of the exploitation of mineral resources, the adaptation of organisms and processes in novel ecosystem systems in urbanindustrial landscapes contributes to a significant increase in biodiversity.
The third part of the book deals with dynamic processes, changes in time and space, and partially understood temporal and spatial patterns in ecosystem processes. Particular attention is paid to the process of succession. Colonization of newly created open spaces by living organisms is a common and dynamic process. At the same time, the potential and importance of this process is underestimated in practical land development activities in urban and industrial areas.
The fourth part of the book characterizes the mechanisms by which the aboveground and underground parts of ecosystems operate and focus on the flow of water and energy as well as the circulation of micro and macro elements, including carbon, as a key element determining life on Earth. Cycles between terrestrial and aquatic ecosystems are compared. The importance of aquatic and aquatic ecosystems (Wetland ecosystems) for such global processes as water retention, carbon sequestration, and maintaining and increasing biodiversity is emphasized. It shows the role of individual groups of organisms in ecosystem processes through trophic interactions (nutrition relationships). With regard to the main goal of the book, it is important to refer in this part to changes that occur in ecosystems as a result of disturbances.
The fifth part presents the potential and documented possibilities of using
the concept of natural capital in relation to environmental conditions that emerged along with the gradient of the subsoil structure and water conditions of habitats in contemporary urban and industrial landscapes. The following section presents the results of research on the species composition and diversity of communities in relation to various groups of organisms in various habitats of mineral substrates. The elements of functioning of novel ecosystems are characterized.
They are presented taking into account the possibility of providing ecosystem services. Novel ecosystems are self-sufficient, and in the face of environmental changes introduced by humans, they become resistant to the influence of global change factors. Examples of post-industrial areas for which individual ecosystem services in the ecosystems of urban-industrial landscapes have been recognized and identified are presented.
The sixth part is focused on various aspects of the current and future possible and recommended understanding, education and application of the ideas of natural capital, new ecosystems and environmental health and ecosystem services inextricably linked to the conditions of human life. Novel ecosystems are particularly important for the regulation of ecosystem services. It was shown how the management of the transformed elements of the terrestrial, swamp and water environment, which were generated after the exploitation of mineral resources, is
necessary for the social responsibility of business. The need to develop a new approach in post-mining land management practices is demonstrated.
The book is a summary and update of natural knowledge, which is very
valuable in a dynamically changing environment. It will also enable a more
conscious management of the natural environment while preserving its full potential.

Coal is the main energy carrier in Poland and is still of key importance in ensuring the country's energy security. Despite the deteriorating mining and geological conditions, rising production costs, and the European Union's climate policy (European Green Deal), coal will still play a decisive role in Poland's energy mix in the coming years.
How it happened with coal, is and will be - the book we present to the Reader is published on the occasion of the 20th anniversary of the Katowice Branch of the Industrial Development Agency SA. The branch was established on March 1, 2003, and the purpose of its creation was to collect data on the restructuring process of the hard coal mining industry.

The publication is the result of the work of researchers representing scientific units and the Industrial Development Agency, Branch in Katowice, and covers selected issues related to hard coal mining.

The monograph opens with a chapter by Rafał Sołtys and Mirosław Skibski, which is a short review of restructuring programs for the hard coal mining sector since 1989. The material also presents selected organizational changes in the sector until 2022 and constitutes a background for further considerations by subsequent authors. Rafał Sołtys and Mirosław Skibski have been associated with the Katowice Branch of the Industrial Development Agency since its establishment.

The restructuring process of the hard coal mining industry is monitored. Since 2003, it has been run by the Industrial Development Agency SA. The next chapter by Beata Barszczowska is devoted to monitoring this process in the years 2020–2023. The material also raises the issue of controlling the spending of budget funds allocated for restructuring processes.

In the third chapter, Zbigniew Grudziński, Urszula Ozga-Blaschke and Katarzyna Stala-Szlugaj present an analysis of the price situation of thermal and coking coal on the international and domestic markets over the last 20 years, along with the factors shaping these prices. The authors also referred to the Polish carbon indices PSCMI_1 and PSCMI_2 published on the website polskirynekwegla.pl run by the Katowice Branch of the Industrial Development Agency.

Can coal still be considered to ensure energy security in Europe? This question is asked in the next, fourth chapter by Radosław Szczerbowski. The author also deals with the issue of the current state of the coal industry and strategies for the development of energy systems in selected European countries in the context of coal use.
The next chapter is an attempt to identify the main trends in the narrative surrounding the energy transformation of hard coal mining. This task was undertaken by Joanna Mazurkiewicz. The material is a summary of part of the research conducted in the Tipping+ project, implemented by the Institute of Structural Research as part of the Horizon 2020 program.

In chapter six, Beata Klojzy-Karczmarczyk presents an assessment of the leaching of pollutants from hard coal mining waste. The material analyzed was selected on the basis of available literature and many years of the author's own research.
In chapter seven, Alicja Stefaniak, Katarzyna Suszek and Łukasz Iwański present changes in legal regulations relating to mining qualifications and training in mining and their impact on the safety of employees of mining plants. The authors made a cross-sectional review of these regulations, starting from the Second Polish Republic to the currently proposed changes to the Geological and Mining Law.

The topic of education and qualifications in the mining sector is one of the topics discussed in the material prepared by Anna Kielerz. The author, in chapter eight, also analyzed changes in the employment sector in the period 2003–2022.
The aim of the penultimate chapter is to assess changes in the state, structure and size of the hard coal resource base in Poland from 1990 to 2022. The author, Eugeniusz Jacek Sobczyk, emphasizes that in the period under study, the state of industrial resources, for reasons other than operational ones, decreased by 10 4 billion Mg. It also draws attention to important issues related to the future of coal, such as the deteriorating mining and geological conditions of the extraction process, decreasing effective working time and the increasing level of natural hazards.
The book ends with Artur Dyczka's chapter Mining 4.0 towards an intelligent deep mine of the future, in which, among other things, the author presented a proposal for the architecture of a production management system based on the Demand and Quality Driven Management System. The author indicated its basic functionalities and groups of IT solutions available on the market, the skillful implementation of which should lead to the development of effective, efficient and lasting solutions in the field of production management.

This book aims to present an alternative based on natural processes and an environmental approach to post-excavation site management, e.g., post-coal mining heaps. These sites are places where various minerał excavation by-products are collected. Nevertheless, some post-mineral excavation sites are oligotrophic, terrestrial, wetland, and water habitat islands, providing unique biodiversity enrichment in the landscape. These oligotrophic minerał habitats are essential in over-fertilized, eutrophic, agricultural and urban-industry surroundings. Some post-mineral excavation sites are places where the wildlife can develop and support the functional processes of novel ecosystems. Implementing the newest biogeochemical and comprehensive knowledge into urban-industry landscape management will help to establish the ecosystenYs processes and environmental functioning. There are several post-industrial sites in Europę where the wildlife areas developed due to natural processes, are becoming wildlife hotspots in densely populated urban-industry areas. In this respect, many of the oligotrophic minerał terrestrial, wetland, and water habitats of anthropogenic origin should not be categorized as environmentally dangerous and undergo economic utility-focused reclamation. Facing the actual environmental constraints of the Anthropocene Epoch, the book's chapters presenting the natural basics and perquisites ofthe environmental ecosystem mosaics, will be interesting for a broad rangę of environmentalists (scientists and students), miners, economists, and sociologists.

Prowadzona w JSW SA w całym ciągu produkcyjnym kontrola parametrów jakościowych węgla, uzupełniona wynikami profilowań geologicznych i modelowania złoża, daje szansę zrozumienia genezy występujących w złożu zaburzeń oraz będzie w przyszłości stanowić fundament budowy zupełnie nowego podejścia do planowania i rozliczania produkcji górniczej.
Wiarygodność informacji dotyczącej wielkości zasobów oraz jakości węgla, który ma być eksploatowany, stanowi jedną z kluczowych informacji, które są niezbędne dla prawidłowego funkcjonowania kopalni węgla kamiennego. Proces optymalizacji kosztowej w sferze działalności operacyjnej może być skutecznie przeprowadzony tylko wówczas, gdy Spółka będzie posiadała dogłębną wiedzę na temat wszystkich ponoszonych kosztów oraz będzie mogła szybko reagować na zmiany zachodzące w sferze produkcyjnej.
Do realizacji największego na świecie w latach 2017-2020 wdrożenia informatycznego systemu do planowania produkcji górniczej zabrano się w Jastrzębskiej Spółce Węglowej metodycznie podpisując odpowiednie porozumienia z Politechniką Śląską i krakowską AGH w celu pozyskania młodej kadry geologicznej do wdrożenia i obsługi Systemu. Po wcześniejszym sprawdzeniu "w boju” przyjęto do pracy w kopalniach JSW SA 17 geologów.
The control of coal quality parameters carried out at JSW SA throughout the production chain, supplemented by the results of geological profiling and deposit modelling, provides an opportunity to understand the genesis of the disturbances occurring in the deposit and will in the future form the basis for building a completely new approach to planning and accounting for mining production.  The reliability of information on the size of resources and the quality of coal to be exploited is one of the key information that is necessary for the proper functioning of a hard coal mine. The process of cost optimization in the sphere of operational activity can be effectively carried out only if the Company has in-depth knowledge of all costs incurred and will be able to react quickly to changes taking place in the production sphere.  The implementation of the world's largest IT system for mining production planning in 2017-2020 was undertaken at JSW SA.

Prezentowana na kartach niniejszej książki koncepcja automatyzacji i monitoringu procesu produkcyjnego LW Bogdanka SA stanowi jądro idei budowy Inteligentnej Kopalni, dla której kluczowe jest powołanie do życia i odpowiednie usankcjonowanie w pełni decyzyjnego Centrum Zaawansowanej Analityki Danych (CZAD), w którym istotne informacje z systemów monitorowania i wizualizacji produkcji będą analizowane i na bieżąco raportowane kierownictwu kopalni.
Nie ulega wątpliwości, że reagowanie w czasie rzeczywistym na ewentualne
nieprawidłowości, podejmowanie szybkich i trafnych decyzji, wpłynie na uzyskanie prawdziwego obrazu posiadanych zdolności produkcyjnych oraz możliwości poprawy własnej rentowności, nie zaburzając w istotny sposób funkcjonowania
Dyspozytora Ruchu Zakładu Górniczego.
Badania przeprowadzone przez autora potwierdzają stwierdzenie, iż zanieczyszczenie węgla jest procesem niekorzystnym, wywierającym negatywny wpływ na efektywność pozyskiwania urobku, jednak istnieją możliwości sterowania jego wielkością zarówno poprzez wykorzystanie dostępnych rozwiązań technologicznych, jak i technicznych, zmieniających proces eksploatacji złoża, a skala wpływu zanieczyszczenia na efektywność pozyskiwania urobku może być kontrolowana i oceniana przy wsparciu odpowiednich rozwiązań informatycznych.
Ważnym aspektem pracy była ocena możliwości wykorzystania wiedzy na temat prognozowanej skali zanieczyszczenia urobku w procesie harmonogramowania produkcji górniczej. Jak ustalono, postęp w zakresie informatyzacji procesów
planowania i rozliczania produkcji górniczej pozwala na sprawne modelowanie
formy złoża oraz jego parametrów jakościowych.
Przedstawiając w pracy własną koncepcję, autor w pełni uznaje dorobek naukowy, zawarty w dotychczasowych pracach z zakresu badanego zagadnienia – dorobek, który w bezpośredni lub pośredni sposób stworzył przesłanki do opracowania
zasad budowy systemu zarządzania jakością urobku w kopalni węgla kamiennego.
Praca stwarza podstawy do projektowania systemów eksploatacji oraz prognozowania wielkości zanieczyszczenia urobku w zależności od warunków górniczo-geologicznych eksploatacji. Istnieje również możliwość wykorzystania opracowanej metodyki do celów praktycznych w przypadku kopalń o innych warunkach geologiczno-złożowych oraz dla różnych systemów eksploatacji.

We present to the Reader an album dedicated to extraor dinary minerals. The people who deal with them on an everyday basis are mainly those who are no strangers to the underground passages of the KGHM Polska Miedź S.A. mines. Minerals are and have been a source of inspiration for many artists. Their enthralling charm was admired and appreciated already in antiquity. It is commonly believed that this charm is encapsulated both in their form and the wide palette of colours. The encyclopaedia entry for min erals, which reads that a mineral is a “naturally occurring homogeneous solid with a definite chemical composition and a highly ordered atomic arrangement; [...] usually formed by inorganic processes” is practically unintelligible to a common reader and would probably discourage any one from viewing this album, while what we have in mind is exactly the opposite. The presented minerals come from the collection of Henryk Kantor – a miner whose life’s passion they have become, and from the collections of the Geological Museum of the AGH University of Science and Technology (Akademia Górniczo-Hutnicza). It should also be noted that this album was first published, in a slightly changed form, in 2008 to celebrate the 21st World Min ing Congress and the 50th anniversary of the World Min ing Congresses Organization. Today, it is presented to the Readers to mark the 50th anniversary of Polska Miedź. I would like to quote here, as I did previously, the words of Ignacy Domeyko – a distinguished geologist, discoverer of many of Chile’s copper ore deposits and rector of the University of Chile in Santiago – who in his memoirs Moje podróże. Pamiętniki wygnańca 1831-1838 (My Travels: Memoirs of an Exile) recounts the impression the world of minerals made on him: “I only remember that, when after a day’s work I was resting until midnight at the very bottom of that mine, by chance I saw a remark- ably well preserved ammonite where a particularly rich ore deposit sat within the rock. The ammonite’s coils and streaks, which evoked in my mind the image of a beautiful wom an’s braided hair, were so clearly and vividly delineated on the candlelit vaulting of the gallery that in the light of the flickering flames it appeared as though the longe xtinct animal had returned to life on the rock wall.” The opportunity to present this unique collection of minerals in an album published under an interchangeable title “The world of Minerals of Polish Copper” is a result of passion of many people. In particular the collecting pas sion of Henryk Kantor and Professor Adam Piestrzyński of AGH who provided commentary to the album. This al bum could not be published if it weren’t for the passion of a few people associated with the Foundation for AGH. We sincerely hope that thanks to these passions and because of this publication the underground world of minerals of Polska Miedź will see daylight and will shine with a secret brilliance hidden “in the stone”.

W roku bieżącym 2005 mija 30 lat od chwili, gdy w styczniu 1975 roku ówczesna Rada Ministrów podjęła decyzję o budowie Kopalni Pilotująco-Wydobywczej Lubelskiego Zagłębia Węglowego we wsi Bogdanka. W lutym tego samego roku utworzone zostało nowe przedsiębiorstwo państwowe o nazwie "Kopalnie Lubelskiego Zagłębia Węglowego w Budowie", którego głównym celem było górnicze zagospodarowanie odkrytych i udokumentowanych bogatych złóż węgla kamiennego na Lubelszczyźnie. Minione 30 lat to szmat czasu i kawał historii. To już drugie pokolenie pracowników kopalni, biorąc pod uwagę 25 letni okres aktywności zawodowej większości górników pracujących pod ziemią. Patrząc na dzisiejszy stan firmy, Lubelski Węgiel "Bogdanka" S.A., jej silną, ugruntowaną i stabilną sytuację techniczną i ekonomiczną, nie sposób choć na moment nie wrócić do przeszłości, do początków tego 30-lecia i przypominać co było zamiarem tamtych czasów, a co zostało dziś osiągnięte. Pierwotne plany budowy LZW zakładały budowę 7 kopalń z wydobyciem 25 mln rocznie, przesuniętych w budowie zaledwie o kilka lat. Była to typowa czasów "epoki Gierka" zaplanowana gigantyczna budowa, która nie uwzględniała jednak rzeczywistych warunków LZW. Były więc plany budowy wielkiego scentralizowanego zaplecza, budowy nowych dróg szybkiego ruchu, lotniska i 100-tysięcznej Łęcznej. Wdarcie się kurzawki z warstwy albu na głębokości 600 m w szybie 1.1 w październiku 1979 roku, prowadzące do zniszczenia obudowy szybowej i zatopienia dwóch wykonanych już szybów, dokonało już wówczas korekty tych planów. Później były długie lata 80-te mozolnej i konsekwentnej pracy nad opanowaniem zarówno warstwy kurzawkowej podczas głębienia szybów, jak i zaciskania wyrobisk korytarzowych i ścian, gdyż słabe skały karbońskie towarzyszące pokładom węgla, bezlitośnie niszczyły stosowane obudowy, sprawdzone ale w warunkach śląskich. Późniejszy sukces "Bogdanki", który osiągnięty został już w połowie lat 90-tych i jest nieprzerwanie przez ostatnie 10 lat konsekwentnie rozwijany i umacniany, ma bez wątpienia swoje korzenie w tej solidnej pracy lat 80-tych. Bez opanowania podstawowych trudności w zakresie prowadzenia i utrzymania wyrobisk górniczych w warunkach reologicznego górotworu LZW i zbudowania zrębów kopalni w postaci głównych wyrobisk podszybi w Bogdance i Nadrybiu, wykonania przekopów łączących oba pola, komór funkcyjnych itp., oraz dopracowania się obudów pozwalających utrzymanie wyrobisk, w tych warunkach w długich okresach czasu, późniejsza restrukturyzacja już w nowych realiach społeczno-politycznych nie byłaby możliwa. Dzisiejsza pozycja kopalni "Bogdanka" to jednak przede wszystkim wydajna i ofiarna praca obecnej załogi, która w skutek prowadzonej restrukturyzacji oraz ograniczeń zatrudnienia, w ostatnim dziesięcioleciu zmieniała się bardzo nieznacznie. Jest to załoga doświadczona, dobrze identyfikująca się z własnym przedsiębiorstwem i pracująca bardzo wydajnie. Z myślą o naszej załodze i w podziękowaniu za dobrą pracę powstał zamiar przygotowania niniejszego "Albumu". Intencją Zarządu było, aby każdy pracownik kopalni z 3.200 tysięcznej załogi był upamiętniony na fotografii oraz wymieniony z nazwiska na stronach "Albumu". Niezależnie od tego w "Albumie" zamieściliśmy rejestr byłych pracowników kopalni, którzy przeszli na rentę lub emeryturę, a których wkład pracy pozostał w dzisiejszym dorobku kopalni. Mimo, że plany budowy 7 kopalń z przed 30 lat nie zostały zrealizowane i kopalnia "Bogdanka" jest wciąż jedyną, samotną kopalnią w Lubelskim Zagłębiu Węglowym, to mamy powody do zadowolenia i satysfakcji z osiągniętych wyników. Dzisiejsza kopalnia "Bogdana" jest, bowiem o wiele większa niż ta planowana 30 lat temu. Obecny obszar górniczy to suma obszarów K-1 i K-2, a zamierzamy powiększyć ten obszar o znaczną część obszaru K-3. Dzisiejsze wydobycie kopalni na poziomie 24.000 ton na dobę, to blisko dwa razy więcej niż planowane 14.400 ton na dobę. A realizujemy przecież program inwestycyjny zmierzający do zwiększenia zdolności wydobywczej do poziomu 40.000 ton na dobę. Już dziś jesteśmy największą, pod względem wydobycia kopalnią, a mamy szansę umocnić się na tym pierwszym miejscu. Z okazji Jubileuszu XXX-lecia, składam wszystkim pracownikom kopalni, zarówno tym obecnym, jak i byłym, oraz ich Rodzinom, dobrego zdrowia i dalszych sukcesów, a także osobistej satysfakcji, że nasza praca w Bogdance przyniosła tak dobre wyniki.

Although some of a great number of International Organizing Committee Members and personalities co-operating with the World Mining Congress during the 50 years have already passed away, a historical memory should remain about all of them, in particular of those who already departed (names bolded) as well as of these who are still among us. Some opinions, comments or memories of the majority of the most outstanding IOC members (for instance: Professor Krupinski, Mr. H. Collins and Professor Whetton from the UK, Professor Fettweis from Austria, Professor Dokukin from the USSR, Professor Manana from Spain, Mr. Brand from Germany, Professor Knissel from Germany, Professor Ghose from India, Professor Faller from Hungary, Professor Boshkov from the USA, Professors Dokukin and Mielnikov from the USSR, Mr. Gutierrez from Mexico, Professor Lisowski from Poland, Mr Malara from Poland, Dr Mitrega from Poland, Mr. Ciszak from Poland and many others) will also be presented in this study.
W ciągu minionych 50 laty musieliśmy pożegnać wielu Członków Międzynarodowego Komitetu Organizacyjnego (IOC – International Organizing Committee), oraz wiele osobistości współpracujących ze Światowym Kongresem Górniczym. Pamiętając o tych, którzy odeszli (nazwiska wytłuszczone), nie możemy zapominać o tych, którzy nadal są wśród nas i stanowią o sile tej organizacji. W niniejszym opracowaniu pozwoliłem sobie przedstawić niektóre opinie, uwagi i wspomnienia o najbardziej cenionych członkach Międzynarodowego Komitetu Organizacyjnego – ludziach, którzy najmocniej odcisnęli swoje piętno na ponad pięćdziesięcioletniej historii tej organizacji, bez których nie mogłaby ona powstać i normalnie funkcjonować. Do grona tych ludzi bez wątpienia należą: prof. B. Krupiński, H. Collins, prof. Whetton, prof. G. Fettweis, prof. R. Manana, W. Brand, prof. W. Knissel, prof. A. K. Ghose, prof. G. Faller, prof. S. Boshkov, profesorowie A. W. Dokukin i N. W. Mielnikow, J. Gutierrez, prof. A. Lisowski, J. Malara, dr J. Mitręga, E. Ciszak i wielu innych.

Despite the difficult material conditions, he did not give up his studies. He continued them successively at several universities, changing his place of residence depending on the possibility of obtaining a job. In 1917 he enrolled at the Faculty of Engineering of the Lviv Polytechnic, at the same time he worked at the Galicia Reconstruction Headquarters. After the end of the war, in the years 1919-1922, he worked at the Ministry of Public Works on the construction of the Commercial Port in Warsaw and at the same time continued his studies at the Faculty of Engineering of the Warsaw University of Technology. In 1922 he started working at the Waterways Authority in Krakow and returned to mining studies at the Mining Faculty of the Mining Academy, where in 1924 he obtained a diploma of mining engineer. After obtaining his diploma, he took the position of the manager of mining works in the "Modrzejów" mine. Encountering difficult, practical problems prompted the young engineer to look for solutions using the knowledge acquired during his studies in the field of mining, hydromechanics and thermodynamics.
In the first place, these were two issues: liquid filling and the impact of thermal factors on the ventilation of mines and air flow in their ventilation networks, as well as on disturbances of those flows that occur during underground fires. The study of the first of these issues entitled "Liquid backfill movement in silting pipelines" was submitted as a doctoral dissertation at the Mining Faculty of the Mining Academy.
Witold Budryk, PhD, Eng., submitted the second study, entitled "Thermal Depression", as a habilitation dissertation in 1929, obtaining the title of habilitated doctor in December of the same year. Both works are of great importance both for science and for mining practice, and their results, valid to this day, are of fundamental importance for scientific research undertaken by other researchers in the field of liquid backfill and ventilation of mines and combating fire hazards.
Recognition for the results of his doctoral and habilitation theses, great intelligence, outstanding perceptiveness and great intuition allowed Witold Budryk to have a quick scientific career. In 1928, after obtaining the title of doctor of technical sciences, he was engaged as an assistant professor and lecturer at the Department of Mining I and Mechanical Processing at the Faculty of Mining, and a few months later, after the death of the head of the Department, Professor Henryk Czeczott, he took over the management of this Department. Already in the following year (1929) he habilitated, and in 1930 he was appointed associate professor.
Such a dynamic beginning of his scientific career – submitting two serious dissertations: doctoral and habilitation in less than two years – was the result of Witold Budryk's interest in current issues faced by mining practice, as well as reflections during studies, internships and several years of work in industry. The results of these long-term observations, investigations and experiences – once the decision to devote oneself to scientific work was made – remained only to be put in order and put on paper.
Pierwszy tytuł doktora nauk technicznych z zakresu górnictwa w Polsce został nadany uchwałą Senatu Akademii Górniczej dnia 16 czerwca 1928 roku na wniosek Rady Wydziału Górniczego z dnia 12 czerwca 1928 roku. Doktorantem, który po zdaniu egzaminu i obronie rozprawy doktorskiej został pierwszym doktorem wówczas jeszcze Akademii Górniczej, był świetnie zapowiadający się młody inżynier górniczy Witold Budryk, pracownik kopalni „Modrzejów”, późniejszy profesor Akademii i wybitny uczony, który miał się już w krótkim czasie cieszyć powszechnym uznaniem i autorytetem w środowisku górniczym tak w kraju jak i za granicą.
Witold Budryk urodził się 8 marca 1891 roku w Białymstoku w rodzinie pracownika kolei. Po ukończeniu Szkoły Realnej i zdaniu egzaminu dojrzałości wstąpił do Instytutu Górniczego w Petersburgu. Podjęte studia górnicze przerwał mu w roku 1914 wybuch pierwszej wojny światowej, a trudne warunki materialne zmusiły do podjęcia pracy w górnictwie. Pracował jako praktykant kolejno w trzech kopalniach Zagłębia Dąbrowskiego: „Milowice”, „Mortimer” i „Niwka”. Ze studiów, mimo trudnych warunków materialnych, nie zrezygnował. Kontynuował je kolejno na kilku uczelniach, zmieniając miejsce zamieszkania w zależności od możliwości pozyskania pracy. W roku 1917 zapisał się na Wydział Inżynierii Politechniki Lwowskiej, pracował równocześnie w Centrali Odbudowy Galicji. Po skończeniu wojny, w latach 1919-1922, pracował w Ministerstwie Robót Publicznych przy budowie Portu Handlowego w Warszawie i jednocześnie kontynuował studia na Wydziale Inżynierii Politechniki Warszawskiej. W roku 1922 podjął pracę w Zarządzie Dróg Wodnych w Krakowie i wrócił do studiów górniczych na Wydziale Górniczym Akademii Górniczej, gdzie w roku 1924 uzyskał dyplom inżyniera górniczego. Po uzyskaniu dyplomu objął stanowisko kierownika robót górniczych w kopalni „Modrzejów”. Zetknięcie z trudnymi, praktycznymi problemami skłoniło młodego inżyniera do poszukiwania na drodze naukowej rozwiązań wykorzystujących nabyte w czasie studiów wiadomości z zakresu górnictwa, hydromechaniki i termodynamiki.
W pierwszej kolejności były to dwa zagadnienia: podsadzki płynnej oraz wpływu czynników termicznych na przewietrzanie kopalń i rozpływ powietrza w ich sieciach wentylacyjnych, a także na zaburzenia tych przepływów, które występują w czasie pożarów podziemnych. Opracowanie pierwszego z tych zagadnień pod tytułem „Ruch podsadzki płynnej w rurociągach zamulaniowych” zostało przedłożone jako rozprawa doktorska na Wydziale Górniczym Akademii Górniczej.
Opracowanie drugiego, pod tytułem „Depresja cieplna”, dr inż. Witold Budryk przedłożył jako rozprawę habilitacyjną w roku 1929, uzyskując w grudniu tegoż roku tytuł doktora habilitowanego. Obie prace posiadają duże znaczenie tak dla nauki, jak dla praktyki górniczej, a ich wyniki, aktualne do dziś, mają podstawowe znaczenie dla badań naukowych podejmowanych przez innych badaczy w zakresie podsadzki płynnej oraz przewietrzania kopalń i zwalczania zagrożeń pożarowych.
Uznanie dla wyników prac – doktorskiej i habilitacyjnej, duża inteligencja, wybitna spostrzegawczość i ogromna intuicja pozwoliły Witoldowi Budrykowi na szybką karierę naukową. W roku 1928, po uzyskaniu tytułu doktora nauk technicznych, został zaangażowany na stanowisku adiunkta i wykładowcy w Katedrze Górnictwa I i Przeróbki Mechanicznej na Wydziale Górniczym, a w kilka miesięcy później, po śmierci kierownika Katedry, profesora Henryka Czeczotta, objął kierownictwo tej Katedry. Już w roku następnym (1929) habilitował się, a w roku 1930 został mianowany profesorem nadzwyczajnym.
Tak dynamiczny początek kariery naukowej – złożenie dwu poważnych rozpraw: doktorskiej i habilitacyjnej w przeciągu niespełna dwu lat – był wynikiem zainteresowania Witolda Budryka aktualnymi zagadnieniami, z którymi borykała się praktyka górnicza, oraz przemyśleń w czasie studiów, praktyk i kilku lat pracy w przemyśle. Wyniki tych długoletnich spostrzeżeń, dociekań i doświadczeń – z chwilą podjęcia decyzji poświęcenia się pracy naukowej – pozostało już tylko uporządkować i przelać na papier.

The history of the publication of the book, which the reader holds in his hands, is quite long, and the final shape was given to the work by the hero himself – Professor Stanisław Knothe.
When asked to write an introduction and suggest a title, I decided that the title we proposed ("Silva rerum of Professor Stanisław Knothe") best reflects the nature of this publication.
Well, since our proposal was accepted by the Professor, we are forced to make some clarifications about this puzzling title. It refers to manuscript, mostly seventeenth-century books, collections of various contents, which were called silva rerum (Latin for "forest of things"). Professor Janusz Tazbir, dealing with the history of Polish customs and culture and religious relations in the sixteenth and eighteenth centuries, writes about it in "Silva rerum historicarum" – a collection of sketches, studies and essays.
The collections called silva rerum (apparently for the first time the Roman orator and politician Cicero resorted to this term, using the phrase in his famous work "Deoratore") was the favorite reading of the Polish nobility. As Professor Tazbir writes, these were handwritten books, full of various texts that interested their owners. Often borrowed, they were supplemented by subsequent readers; Professor Tazbir states m.in.: "Although more than three hundred years have passed since the flowering of this literature, the content of 'silva rerum' is only partially known to its researchers. A whole lot of them were destroyed along with the manors and mansions of the owners. It was not until the nineteenth century that silva rerum was used in search of primarily poetic texts. Neither the printers were interested in their earlier publication, because there was no demand for them, nor readers, because what more delicious morsels they found in manuscripts, nor the authors themselves, because the possible publication brought neither money nor fame.
It is no different with our "Silva rerum of Professor Stanisław Knothe", which also contains various information, facts and anecdotes, but also original documents of extraordinary importance, such as the text of the Professor's doctoral thesis, classic curriculum vitae, copies of diplomas or a text presenting "Knothe's theory in mining science and practice".
All this, in our opinion, makes the use of the aforementioned term in the case of this beautiful book absolutely justified. We invite you to read and commune with an extraordinary and very outstanding Polish scientist of world renown.

Historia publikacji książki, którą Czytelnik trzyma w dłoniach, jest dosyć długa, a ostateczny kształt nadał dziełu sam bohater – Profesor Stanisław Knothe.
Poproszony o napisanie wstępu i zasugerowanie tytułu, uznałem, że tytuł, jaki zaproponowaliśmy („Silva rerum Profesora Stanisława Knothe”) najlepiej oddaje charakter tej publikacji.
Cóż ponieważ nasza propozycja została zaakceptowana przez Profesora, jesteśmy zmuszeni poczynić kilka wyjaśnień w sprawie tego zagadkowego tytułu. Nawiązuje on do rękopiśmiennych, przeważnie XVII-wiecznych książek, zbiorów różnych treści, które nazywano właśnie silva rerum (łac. „las rzeczy”). Pisze o tym w „Silva rerum historicarum” – zbiorze szkiców, studiów i esejów – Profesor Janusz Tazbir, zajmujący się dziejami obyczajów i kultury polskiej oraz stosunkami wyznaniowymi w okresie XVI–XVIII wieku.
Zbiory nazywane silva rerum (podobno po raz pierwszy uciekł się do tego określenia mówca i polityk rzymski Cyceron, używając sformułowania w swoim słynnym dziele „Deoratore”) stanowiły ulubioną lekturę polskiej szlachty. Jak pisze Profesor Tazbir, były to książki pisane ręcznie, pełne rozmaitych tekstów, które zainteresowały ich posiadaczy. Często wypożyczane, były uzupełniane przez kolejnych czytelników; Profesor Tazbir stwierdza m.in.: „iż choć upłynęło przeszło trzysta lat od chwili rozkwitu tej literatury, zawartość ’silva rerum‘ jest tylko częściowo znana jej badaczom. Całe ich mnóstwo uległo zresztą zagładzie wraz z dworami i dworkami posiadaczy. Dopiero w XIX stuleciu sięgnięto do silva rerum w poszukiwaniu przede wszystkim tekstów poetyckich. Ich wcześniejszą publikacją nie byli zainteresowani ani drukarze, bo nie istniało na nie zapotrzebowanie, ani czytelnicy, gdyż co smakowitsze kąski znajdowali w rękopisach, ani też sami autorzy, ponieważ ewentualna publikacja nie przynosiła ani pieniędzy ani sławy”.
Nie inaczej jest i z naszym „Silva rerum Profesora Stanisława Knothe”, które także zawiera różnorodne informacje, fakty i anegdoty, ale również oryginalne dokumenty niezwykłej wagi jak choćby tekst pracy doktorskiej Profesora, klasyczne curriculum vitae, kopie dyplomów czy tekst prezentujący „Teorię Knothego w nauce i praktyce górniczej”.
To wszystko naszym zdaniem czyni użycie wspomnianego określenia w przypadku tej pięknej książki absolutnie zasadnym. Zapraszamy do lektury i obcowania z niezwykłym i jakże wybitnym polskim naukowcem światowej sławy.

The picture of the mining industry in Lublin region painted on the pages of this album is a fruit of self-sacrificing work of the builders of the Basin during the last thirty years. The great transforma tion was started by the discovery of the deposit made by Professor Jan Samsonowicz and its do cumentation by a team of geologists from State Geological Institute led by Józef Porzycki.
The exploratory and documentary research launched as a result of this discovery allowed for determining the size and reserves of the deposit which in the future may decide about the energy safety of our country.
Lublin’s adventure with mining started from a great plan of building 7 mines with a great centralised infrastructure, cities, roads and an airport. However, only one modest mine K-1 (presently LW “Bogdanka”) was constructed in the end. Its construction was finished with the mine’s own capital after the financing from the central budget was withheld in 1989.
On 30th November 1982 first longwall was launched in “Bogdanka” mine, starting coal extraction in Lublin Coal Basin.
During many subsequent years, methods and solutions were developed which in the end introduced the mine to the leading group of not only Polish, but also global coal mines.
In the year of 30th anniversary of coal mining in Lubelskie region, the entire crew of miners working underground, the crew of the processing plant, engineering, technical, eco nomic and administrative staff of our Company deserve great compliments, respect and thanks for the great crea tion of a very efficient and effective mining enterprise which is the pride of the region and an important element of the country’s economy.
The present day lays new challenges and new problems in front of us. We consistently implement the policy of effi ciency growth in all our actions which gives us the perspec tive for further quick development.
We would like the history presented in this album to be come a valuable souvenir and a source of information about Bogdanka mine – the biggest, the best and so very dear to our hearts.
By presenting our history to you, we dedicate it to all those who tied their and their beloved fate with the mine for which they always put in a lot of effort and work. We give you all our greatest compliments.
On 1st January 2015, 40 years will pass since the decision about the beginning of construction of a pilot mine in Bogdanka. The first longwall started 30 years ago was pretty modest by today’s standards: 100 m long, production under 800... more
On 1st January 2015, 40 years will pass since the decision about
the beginning of construction of a pilot mine in Bogdanka.
The first longwall started 30 years ago was pretty modest by today’s standards: 100 m long, production under 800 t/day, limited by the shafts’ capacity, but its  actual abilities were not much higher at that time. Because of the enormous problems emerging in the first stage of the mine’s construction, such as: going through water-bearing layers (sandwaters), tightening of finished horizontal excavations as well as the necessity of reconstruction of destroyed shaft inlets, the first longwall (exploratory longwall) conducted sole exploitation at ca. 800 t/day until as late as April 1986, so for over 5 years.
The commisioning of S.1.4 shaft in Nadrybie which took place in November 1985 allowed for the mine’s production to increase to ca. 2500 t/day.  In April 1986 a second longwall, no. 2/1 was launched in Bogdanka, and in September 1987 first longwall in Nadrybie (2N). A breakthrough in the coal mining in “Bogdanka” mine took place in November 1988 when after 11 years of construction production shaft S.1.3 came  into use with a hoisting skip of 30 tonnes and capacity of 18 800 tonnes/day.
In the period between 1988 and 1992 the number of operating longwalls
increased relatively quickly (max. 5) with simultaneous quite quick increase of  the mine’s production.
December 1992 is another important date. This is when Coal Processing
Plant came into use, allowing for coal beneficiation and improvement in its quality. The last significant event after 24 years have passed since the government’s decision to stop the construction of K-2 mine was the commisioning of shaft S.2.2 in Stefanów together with its infrastructure.
In today’s realities Stefanów is the third perspective field of Lubelski Węgiel “Bogdanka” S.A. which will allow the mine to double its present production.
The period of last almost 40 years is for the builders of “Bogdanka” mine and its miners is the time of arduous struggle with nature and technical adversities, but – more often – the time of introducing innovative solutions. The time of thorough structural adjustment and creating a base for work efficiency growth and decreasing costs.
The period of last 10 years constitutes for heading for the position of the
leader of Polish coal mining industry (highest efficiency, greatest concentration of production, lowest costs). LW “Bogdanka” S.A. is a 10-time finalist of the Mine of the Year contest, organized for over 20 years by the School of Underground Mining.
The successes of the recent years are the effect of many years of work of an enormous crowd of employees. To them we also dedicate this album. You may find the reminder of the facts preceding it on the pages of this publication.

Its prototype was the album accompanying the XXI World Mining Congress that took place in Krakow and  outgoing sessions in Lubin, Bełchatow, Katowice and  Wieliczka in the year 2008. I believe that the current edition of the album, a bit complex and also including important events for the Polish mining industry, will meet  with no less interest of readers than the album two years ago.
The beginnings of mining around the world and  in Poland are from ancient times, the times of Neolithic flint mines where the wonderful Polish Krzemionki Opatowskie shines, but also times of the first metal
mines; gold, copper and iron mines. It is these latter two metals that significantly accelerated the development of our civilization. This acceleration continues till today.
Although the Bronze Age lasted in various areas of the  Earth for up to three thousand years, the Iron Age is only 1000 – 1500 years old. At the same time the era of the Industrial Revolution, which plays a crucial role for the development of not just mining but for the entire industry, is “only” 100 years. Many consider the Wieliczka mine as the cradle of the Polish mining industry and not just  for salt mining.
The collected photographs are the shortest stories.  They are the shortest, because they occurred in a split  second, citations from the world around us. As such, we  decided to precede and describe them with quotes, sayings and aphorisms, i.e. the shortest literary pronouncements. I hope that the photographs perfectly fit into the role of photography proposed by Ryszard Kapusciński in one of his numerous interviews. He was the master of reportage, one of the most famous Poles in the world of
literature. He described this process as follows: “Photography is primarily capturing the reality that surrounds us. People whose faces we want to keep, landscapes that we want immortalize and events that we are witnesses to. And also the entire complicated life together with its
complex customs. Photograph everything, everything that is alive or dead, just to capture and hold”

The album is a documentation of the Polish mining industry on the threshold of the 21st century. In the pictures we admire the artistic story of the land of coal, zinc, lead, copper and salt. It is a story about Poland, but above all Silesia. The distant shots show industrial sites and mine shafts, we admire the wonderful world of the underworld, where a miner works in a setting so differ ent from that which surrounds us. Observing the land scape, we realize that the reality given to man has been replaced by a reality created by him. We are also aware of the power of technology and its enormous hidden energy. But above all the specificity of mining reality de fines the miners’ activities that are subject to a kind of originality due to the lack of natural light, the presence of various gases, dust, excess water and increasingly high temperatures. It is work performed in adverse con ditions and in direct dependence on nature with which we struggle. Technological progress is not always able to eliminate the nuisance. All this makes the work of a min er special. This diversity of work, a sense of professional pride and solidarity are the direct reasons for creating their own culture and traditions. The presentation of these traditions (preceded by a short essay), as I men tioned earlier, needed to be included in our album. The collected photographs are the shortest stories. They are the shortest, because they occurred in a split second, citations from the world around us. As such, we decided to precede and describe them with quotes, say ings and aphorisms, i.e. the shortest literary pronounce ments. I hope that the photographs perfectly fit into the role of photography proposed by Ryszard Kapusciński in one of his numerous interviews. He was the master of reportage, one of the most famous Poles in the world of literature. He described this process as follows: “Photog raphy is primarily capturing the reality that surrounds us. People whose faces we want to keep, landscapes that we want immortalize and events that we are witnesses to. And also the entire complicated life together with its complex customs. Photograph everything, everything that is alive or dead, just to capture and hold”. The statement should be supplemented by a state ment of one of the most famous intellectuals of the twentieth century, Susan Sontag, derived from the famous collection of essays “On photography”, that “to col lect photographs is to collect the world”. I believe that this is also the case for our album, in which the compiled photographs illustrate the world of miners. I am con vinced that the presented photos taken by people with passion and supplemented with literary commentary will provide unexpected experiences and bring every one closer to this mysterious world.

Ignacy Domeyko, the discoverer of the Chilean cop per deposits and past Rector of the Santiago de Chile University described his memories from the visit to Chile (“My journeys -memoires of the exile” ): …” I only re member that after work until midnight I rested at the bottom of that mine and I saw a well-preserved ammonite at the contact of rich ore vein with the wall-rock. Its coils and strips braided as a plait of a beautiful woman were so clear and distinctly marked at the roof illuminated with miner’s candles that when the lights flicked it seemed that the past animal is still alive and moves…”. In the past the world of minerals facsinated only a few people. Now, it fascinates thousands, in Poland and else where. There are numerous mineral and fossils fairs and exhibitions in the world. The most valuable mineral col lections are owned by technical universities, as e.g., at the Mining Academy in Freiberg or at the Mining University in Sankt Petersburg. The largest world exhibition of min erals at the Freiberg Castle is based upon the collection of the Freiberg Academy. In Poland leading mineral collections are at the AGH University of Science and Technology in Kraków and at the State Geological Institute in Warsaw,
Since millenia the nature has been admired and de lighted for its beauty. It was also the inspiration for the art ists: sculptors, painters, writers, composers and architects. The important part of the nature is the world of minerals, which is still the source of fascination and sensations. Jo hann Wolfgang Goethe, the great poet but also the great enthusiast of mineralogy wrote: …any comprehension begins with admiration…”. This comprehension is currently the passion of many people, particularly geologists but also miners who first see the minerals exposed during the run ning of mining operations.
The minerals presented in the following Album be long to the collection of Mr. Henryk Kantor – the miner who has once been fascinated by the world of minerals occurring in the Polish Copper District and in the whole Lower Silesia region. The collection represents first of all the ore mineralization in the Fore-sudetic Monocline deposits, particularly the typical, disseminated, vein, laminated and massive structures as well as veinlets and secretions in fault zones, breccias and nests filling the karst cavities, and other open spaces in the rocks. Among the presented specimens there are e.g., perfect crystals of selenite formed in karst cavities in the dolomites overly ing the ore zone and downthrown by fault to the min ing level as well as aggregates of multicolored gypsum crystals recently precipitated as secondary mineral in the mine workings. Great attractions of the Album are mul ticolored aggregates of marcasite, pyrite as well as druses and collomorph accumulations of calcite, and also molds of fossil fish found in the Kupferschiefer at the Lubin and the Rudna mines. From the old ”Konrad” Mine nu merous, fine crystals and dendritic aggregates of native copper originate together with beautiful, idiomorphic crystals of blue celestite. Attention should be paid also to chalcopyrite crystals embedded within the milky and pink calcite veins, to ag gregates of copper sulphides and calcite crystals in a geode enclosed in marly carbonates as well as to perfect pyrite crystals growing onto calcite ones (as in a specimen from the ”Lena” Mine).
The number of identified minerals exceeds 4,000. In this number the ore minerals share a fracture of per cent of the Earth’s crust mass. Minerals displayed in this Al bum represent only some tens of species originating from a particular part of the Lower Silesia region and embrac ing mostly phases of a single element – copper – which has been mined here since 45 years by the Polish Copper Company: the KGHM Polska Miedź SA, which is one of the largest world copper producer and, simulatneously, the Golden Sponsor of the XXIst World Mining Kongress. Recently, the number of minerals discovered in the depos it mined by the KGHM exceeds 140. Most of them were discovered by Polish geologists from the AGH-University of Science and Technology in Kraków (Marian Banaś, Adam Piestrzyński, Henryk Kucha and Witold Salamon), from the Jagiellonian University (Czesław Harańczyk) and from the KGHM (Jan Jarosz), and by others.
The following Album is only a small presentation of the world of minerals to the participants of the XXIst In ternational Mining Congress. It is also the credit to the Golden Sponsor of the Congress, and is dedicated to all geologists and miners of the KGHM Polska Miedź SA. We hope that all the Readers of the Album will dis cover the beauty of minerals and will notice the passion which gave rise to its preparation and edition.

The basis for management decision-making processes on an enterprise scale is the economic calculation in a market economy. The theory and practice of management are constantly enriched with new methods of economic calculation, and some of them are already standards required, for example, by financial institutions.
The publication was prepared in three parts. The first part presents simple and dynamic methods of assessing the economic and risk of investment projects – development, reconstruction and modernization. Simple assessment methods include operating profit, net profit, economic added value and simple rates and payback period for capital expenditure. Simple risk assessment methods include break-even points, critical points and safety margins, as well as sensitivity analysis and scenario analysis. Dynamic methods of economic assessment include net present value and dynamic profitability indicators. Dynamic risk assessment methods include the payback period, the mould factor and the standard deviation and confidence factor.
The second part presents the basic elements of economic calculation in the operational phase. In particular, the company's balance sheet, financial result and cash flows are presented. Measures aimed at increasing added value and a strategic scorecard as a management method related to such measures are also presented. The third part is devoted to selected issues in the management of mineral resources. The classification of deposits and their resources is presented, and the method of determining the criteria for the industriality of resources is given. The following section presents the classifications of losses and depletion of minerals and how to assess them economically. Proposals were also made to estimate the value of deposits using the discounted cash balances method and the option method.

In the conditions of constantly increasing and having a global dimension competition for sales and customer markets, new directions of management and economics of enterprises are developing. Individual scientists, consulting companies and company managers participate in this process.
Recently, ie since the nineties of the last century, the direction of research aimed at increasing the market value of enterprises has been developing. Three interrelated areas can be distinguished: the first is to search for measures determining the increase in the value of enterprises, the second concerns management procedures aimed at increasing the value of the enterprise, and the third - is related to the previous two and concerns the use of factors that create the value of the enterprise.
For years, economists have been looking for a single indicator to assess the financial condition of the company, the work of the management board and creating value for shareholders. Such an indicator is currently profit, determined in accordance with the accounting principles and the profitability ratios based on it, in particular the ROA rate of return on net assets, which is the ratio of net profit to the book value of assets and the rate of return on equity, which is the ratio of net profit to the book value of capital own ROE.
A typical option for mining companies is the postponement option, which occurs when a company has a concession to exploit a deposit, but will use the concession, e.g. in two years, anticipating an increase in raw material prices.
The subject of this project is a new strategy for creating the market value of mining enterprises. By the new strategy, we mean the use of new measures of business evaluation, recommending - despite its disadvantages - economic added value and the use of procedures compatible with it, the so-called strategic scorecard.
The project is presented in several chapters. The first chapter presents economic models, i.e. measures aimed at increasing the added value, listing their advantages and disadvantages. The second chapter describes the algorithm for calculating the value added for mining enterprises, providing an example of such calculations for the basic technological line of KGHM Polska Miedź S.A. and the hard coal mining company LW Bogdanka S.A. The third chapter presents the procedure of managing mining enterprises through the so-called strategic scorecard. This procedure is developed in the following chapters describing in turn the strategic factors, operational factors and option factors.
The project was completed with a summary and conclusions addressed mainly to the management of the mine.

Poland's socio-economic policy pursued since 1990 aims to be built an efficient and competitive market economy. To this end, the government implemented a number of system and implements sectoral restructuring programs, including the strategically important one and extremely difficult to implement - the hard coal mining restructuring program.
Reform The mining industry has been and continues to be a constant state interference. The changes are taking place to the rhythm dictated by successive government restructuring programs over the course of sixteen years (1990-2006) there were eight in total and two revisions.
Further restructuring programs implemented with varying intensity and with different control instruments restructuring processes led to an improvement in the economic and financial situation of many mines. It should be noted that this improvement, apart from the undoubtedly effective restructuring measures, the favorable situation on the international market of mineral resources also contributed to this to maintain significant exports.
These elements prompted the authors of the study to submit a methodology project and strategies for limiting production and liquidating hard coal mines, with particular emphasis on formal and legal solutions and the effects of their application for the entire industry.

The political and economic breakthrough that took place in Poland in 1989 created a new situation in the hard coal mining industry. The mining activity had to be subordinated to tasks related to the process of deep restructuring of this industry. The key to achieving profitability and competitiveness of the mining industry has been the adjustment of coal supply to the demand on the domestic and foreign markets, which translates into a significant reduction in production capacity and adapting them to the needs of the sales markets, as well as a significant reduction in employment.
The decline in industrial production and the economic recession in the early 1990s led to a reduction in the demand for coal. The developed production capacity of the hard coal mining industry in 1988 allowed for the extraction of 193 million Mg of coal. In the following years, production decreased, which was the result of adjusting its size to the market demand. In 1993 it was only 130 million Mg, and in 2002 it dropped to 102 million Mg.
In the presented monograph, the authors present the most important results of the research carried out, which led to the implementation of solutions leading to real possibilities of quality control and profitability of production in Coal Mine Piast".
The work presents a synthetic description of the following tasks:
 the first chapter discusses the goals and method of project implementation,
 the second chapter presents the general characteristics of the Coal Mine "Piast", the model of the mine (access method) and the characteristics of the geological and mining conditions of the deposit,
 the third chapter analyzes the economic assessment of the mining plots to be developed, taking into account the uncertainty and risk,

W 1996 roku podczas obrad V Szkoły Eksploatacji Podziemnej - największej konferencji górniczej w Europie - opublikowano książkę pt.: „Eksploatacja cienkich pokładów węgla kamiennego". Była ona podsumowaniem obrad jednej z sesji, w której wzięli udział autorzy
z kilku krajów zajmujący się tą problematyką.

Materiały konferencji, które trzymacie Państwo w ręku, wydane w serii International Mining Forum 2011 prezentują dotychczasowe polskie i światowe dokonania w zakresie eksploatacji cienkich pokładów węgla kamiennego. Wdrażanie techniki strugowej w Polsce realizują młodzi inżynierowie, dla których zautomatyzowany system eksploatacji stanowi prawdziwe wyzwanie wskazujące kierunek dalszego rozwoju - to eksploatacja z minimalnym udziałem ludzi w przodku, przy nowej roli i możliwościach technologii informacyjnych. Tworzą one nowe formy i sposoby obsługi dotychczas realizowanych procesów produkcyjnych, z powodzeniem wykorzystywane w nowej generacji techniki strugowej. Kolejne generacje młodej kadry wkraczającej do kopalń, obdarzone nowym rodzajem umiejętności, a przede wszystkim świadomości cechującej się szczególnym rozumieniem rzeczywistości (rzeczywistością jest przede wszystkim to, co jest na ekranie) są gwarantem, że ten kierunek poszukiwań nowych rozwiązań i dążenie do zatrudniania jak najmniejszej liczby ludzi na dole kopalń będzie coraz silniej rozwijany.
Dotychczasowe doświadczenia trzech kopalń (KWK „Zofiówka", KWK. „Jas-Mos", LW „Bogdanka" S.A.) dowodzą, że istnieją realne możliwości włączenia się polskich firm w dalszy rozwój kolejnych instalacji strugowych.
Wierzymy, że problemy poruszone w tym wydawnictwie oraz podczas podejmowanych dyskusji konferencyjnych stanowić będą idealne podsumowanie dotychczasowych działań podejmowanych w Polsce i na świecie w zakresie wdrażania techniki strugowej w górnictwie oraz wskażą kierunki dalszego rozwoju tej technologii.

Istotnym problemem gospodarowania odpadami w Polsce pozostają odpady wytwarzane przez przemysł wydobywczy, w których ilość znaczący udział mają kopalnie węgla kamiennego. O wadze problemu świadczyć może zapis, w przyjętej w lipcu 2007 r. przez Radę Ministrów „Strategii działalności górnictwa węgla kamiennego w Polsce w latach 2007–2015”. W ramach działań dla osiągnięcia celów strategicznych i cząstkowych wymienia się w „Strategii” w pkt. 7 „Podjęcie przez spółki węglowe działań związanych ze zwiększeniem przychodów poprzez racjonalne gospodarowanie produktami ubocznymi i odpadami (np. metan, skała płonna, woda, złom)”. Skłania to do ponownego spojrzenia na skałę płonną, w wymiarze odpadu, który może zostać wykorzystany gospodarczo.
Monografia składa się z 9 rozdziałów. W możliwie kompleksowy sposób
zilustrowano tematykę gospodarki odpadami z górnictwa węgla kamiennego. Począwszy od prawnych aspektów, poprzez zagadnienia techniczne i ekonomiczne, po praktyczne przykłady zagospodarowania skały płonnej w spółkach górniczych. Dane dotyczące kopalń węgla kamiennego w Polsce pozyskane zostały dzięki uprzejmości pracowników kopalń z materiałów wewnętrznych.
Tematyka problemów telekomunikacji w górnictwie podziemnym rozumiana jako: nadawanie, przesyłanie oraz odbiór informacji jakiejkolwiek natury (głosu, znaków, sygnałów, obrazów czy dźwięków) drogą przewodową, radiową czy optyczną jest... more
Tematyka problemów telekomunikacji w górnictwie podziemnym rozumiana jako: nadawanie, przesyłanie oraz odbiór informacji jakiejkolwiek natury (głosu, znaków, sygnałów, obrazów czy dźwięków) drogą przewodową, radiową czy optyczną jest poruszana na sesjach największej konferencji środowiska górniczego w Polsce: Szkole Eksploatacji Podziemnej już od kilkunastu lat.

Początkowo były to referaty poświęcone głównie zagadnieniom telekomunikacyjnych systemów bezpieczeństwa pracujących w
kopalniach, w tym w szczególności systemom łączności i alarmowania załogi, gazometrii, łączności radiowej, sejsmometrii i lokalizacji zasypanych górników. W miarę rozwoju systemów telekomunikacyjnych i wprowadzania do kopalń coraz to nowszych technologii telekomunikacyjnych pojawiały się referaty dotyczące iskrobezpiecznych systemów łączności ogólnozakładowej, łączności stosowanej w czasie prowadzenia akcji ratowniczych, systemów łączności dyspozytorskiej
i radiowej, szczególnie z wykorzystaniem kabla promieniującego.

Tak ważna problematyka sprawiła, że od kilku lat jedna z Sesji Szkoły Eksploatacji Podziemnej, organizowana wspólnie z pracownikami Zespołu Atestacji Katedry Elektryfikacji i Automatyzacji Górnictwa Politechniki Śląskiej, jest poświęcona systemom telekomunikacyjnym eksploatowanym w kopalniach, w tym w szczególności systemom monitorowania procesów technologicznych.

Tematyka ta jest szczególnie aktualna w kontekście tworzenia dyspozytorni energomechanicznych, czyli stanowisk obserwacyjnych podstawowych maszyn i urządzeń górniczych eksploatowanych w kopalniach. Początkowym ograniczeniem w rozwoju tych systemów był słaby rozwój kopalnianych systemów teletransmisyjnych. Technika światłowodowa w wykonaniu przeciwwybuchowym bezpiecznym optycznie (najczęściej z cechą „op is”) oraz pokonanie problemów
technicznych związanych z naprawią włókien światłowodowych w wyrobiskach podziemnych umożliwiły również szybki rozwój i tego rodzaju usług telekomunikacyjnych.
Stoimy przed specyficznymi problemami (ograniczeniami) jakie stwarza środowisko techniczne podziemi kopalń. Do najważniejszych należy zaliczyć:
- konieczność stosowania urządzeń elektrycznych (telekomunikacyjnych) budowy przeciwwybuchowej, a w kopalniach niemetanowych o stopniu ochrony obudowy min IP54,
- nietypowa struktura wyrobisk objawiająca się małymi (kilkumetrowe) wy-
miarami porzecznymi, w stosunku do ich bardzo dużych (kilometrowych)
wymiarów podłużnych,
- duże nagromadzenie (w ograniczonych przestrzeniach) sieci i urządzeń elektroenergetycznych o bardzo dużych mocach,
- ograniczona ciągłość (pewność) zasilania urządzeń telekomunikacyjnych z sieci elektroenergetycznych, powodowana między innymi nieplanowanymi włączeniami, wywołanymi najczęściej zadziałaniem zabezpieczeń elektroenergetycznych czy metanometrycznych.

Zainteresowanie tą problematyką w czasie obrad każdej Szkoły Eksploatacji Podziemnej jest ogromne, o czym świadczy ilości referatów nadsyłanych na tą sesję i ożywione dyskusje prowadzone w czasie ich prezentowania. To spowodowało, że zagadnieniom monitoringu w procesie eksploatacji złóż jest poświęcona druga już publikacja Szkoły Eksploatacji Podziemnej. W publikacji tej zebrano przede wszystkim referaty poruszające zagadnienia monitoringu technologicznego w kopalniach podziemnych.
Zebrane referaty stanowią podsumowanie jednej z najważniejszych sesji Szkoły Eksploatacji Podziemnej, pt.: Monitoring, sterowanie i wizualizacja procesów podziemnej eksploatacji złóż z lat 2011-2014, które od kilku lat z satysfakcją organizujemy.

Wierzymy, że ta sesja podobnie jak niniejsza MONOGRAFIA będzie cieszyła się tak dużym zainteresowaniem, jak dotychczas również i w przyszłości..

Polskie doświadczenia we wdrażaniu technologii strugowej w głębokim górnictwie węglowym  mogą mieć olbrzymie znaczenie dla
rozwoju techniki strugowej w górnictwie światowym.
Zachłyśnięci wielkimi zasobami węgla coraz częściej czytamy o „peak coal", a eksploatacja cienkich pokładów to przecież jedna z szans wzrostu bazy zasobowej, o czym piszą wszyscy autorzy zajmujący się problematyką eksploatacji cienkich pokładów. Potwierdzają to ostatnie wdrożenia.
W Polsce wdrażanie techniki strugowej realizują młodzi inżynierowie, dla których zautomatyzowany system eksploatacji stanowi prawdziwe wyzwanie wskazujące kierunek dalszego rozwoju - to eksploatacja z minimalnym udziałem ludzi w przodku przy nowej roli i możliwościach technologii informacyjnych. Tworzą one nowe formy i sposoby obsługi
dotychczas realizowanych procesów produkcyjnych, znakomicie i z powodzeniem wykorzystywane w nowej generacji techniki strugowej. Kolejne generacje młodej kadry wkraczającej do kopalń obdarzone nowym rodzajem umiejętności, a przede wszystkim świadomości cechującej się szczególnym rozumieniem rzeczywistości (rzeczywistością jest przede wszystkim to co jest na ekranie) są gwarantem, że ten kierunek poszukiwań nowych rozwiązań i dążenia do jak najmniejszej liczby ludzi zatrudnionych na dole kopalń będzie coraz silniej rozwijany.

Dotychczasowe doświadczenia takich kopalń jak: KWK Zofiówka, KWK Jas-Mos czy wreszcie  LW Bogdanka SA wskazują, że istnieją realne możliwości włączenia się polskich firm w dalszy rozwój kolejnych instalacji strugowych.

Niniejsza publikacja zdominowana jest przez opis działań związanych z wdrażaniem techniki strugowej w latach 2007-2010 w tych trzech kopalniach. Uzupełniają je wybrane prace Autorów (którzy wrazili zgodę
na ponowną publikację) zajmujących się tą problematyką.

Przed Czytelnikiem publikacja, która jest dokumentem obrazującym powrót techniki strugowej do polskich kopalń, ale leż prezentującym możliwości jej rozwoju.


Polish experience in the implementation of plow technology in deep coal mining may be of great importance for
development of the plow technique in the world mining.
Infatuated with great coal resources, we read more and more often about "peak coal", and the mining of thin seams is one of the chances of increasing the resource base, which is mentioned by all authors dealing with the issue of mining thin seams. This is confirmed by recent implementations.
In Poland, the implementation of the plowing technique is carried out by young engineers, for whom the automated mining system is a real challenge indicating the direction of further development - it is mining with minimal human participation in the face with the new role and possibilities of information technology. They create new forms and ways of handling
production processes implemented so far, perfectly and successfully used in the new generation of plow technology. Successive generations of young personnel entering the mines, endowed with a new type of skills and, above all, awareness characterized by a special understanding of reality (reality is primarily what is on the screen) guarantee that this direction of searching for new solutions and striving for as few people employed on the bottom of the mines will be increasingly developed.

The hitherto experience of such mines as: KWK Zofiówka, KWK Jas-Mos and finally LW Bogdanka SA indicate that there are real opportunities for Polish companies to join the further development of subsequent plowing installations.

This publication is dominated by a description of activities related to the implementation of the plow technique in the years 2007-2010 in these three mines. They are complemented by selected works by authors (who gave their consent
for republication) dealing with this issue.

Intensywny rozwój telekomunikacji, jaki aktualnie obserwujemy we współczesnym świecie stawia również nowe wyzwania dla górnictwa podziemnego. Trudno bowiem sobie wyobrazić, iż rozwiązania te nie będą także wykorzystywane w górnictwie, skoro przesłaniem działalności górniczej, w tym także Szkoły Eksploatacji Podziemnej (inicjatora tej publikacji) jest słynna wypowiedź Profesora Bolesława Krupińskiego o tym, iż „Górnik zawsze był, jest i będzie człowiekiem postępu zarówno technicznego jak i społecznego, gdyż tylko postęp, bezustanne doskonalenie technicznych i społecznych warunków pracy, pozwala górnikowi coraz głębiej poznawać tajemnice Ziemi, odkrywać jej skarby, zdobywać je ku pożytkowi powszechnemu, odwracać niebezpieczeństwa, którymi grozi przyroda i wyposażać kraj w siłę tejże przyrody".

Tematyka szeroko rozumianej telekomunikacji w górnictwie jest poruszana na sesjach Szkoły Eksploatacji Podziemnej już od dziesięciu lat. Z tym obszarem działania Szkoły początkowo związane były referaty poświęcone głównie zagadnieniom systemów metanometrycznych i alarmowo-rozgłoszeniowych w podziemnych zakładach górniczych.
Poruszano również problemy dotyczące lokalizacji zasypanych górników oraz możliwości automatycznego monitorowania ruchu załogi. Tematyka ta gościła głównie na sesjach poświęconych zagadnieniom bezpieczeństwa w kopalniach. W miarę rozwoju systemów telekomunikacyjnych i wprowadzania do kopalń coraz to nowszych technologii telekomunikacyjnych pojawiały się referaty dotyczące iskrobezpiecznych systemów łączności ogólnozakładowej, łączności stosowanej w czasie prowadzenia akcji ratowniczych, systemów łączności dyspozytorskiej i radiowej, szczególnie z wykorzystaniem kabla promieniującego. Poruszano również ważną tematykę nadzoru i kontroli zjawisk sejsmicznych z wykorzystaniem metod sejsmoakustycznych, czy mikrosejsmologicznych.

Wspomniane współczesne, dynamicznie rozwijające się technologie telekomunikacyjne stały się również inspiracją dla modernizacji systemów monitorowania procesów technologicznych w podziemnych zakładach górniczych. Wraz z rozwojem techniki światłowodowej obserwuje się dynamiczny rozwój systemów teletransmisyjnych. Niezależnie od tego, w kopalniach, w szybkim tempie rozwijają się także systemy zdalnego sterowania maszyn, urządzeń i elektroenergetycznych pól rozdzielczych. W systemach dyspozytorskich realizowane są różne scenariusze monitorowania, z których najważniejsze to:
-  technologiczny, obejmujący kontrolę wybranej grupy urządzeń powiązanych ze sobą,
- terytorialny, cechujący się tym, iż nadzorowane są różne urządzenia zlokalizowane w jednym rejonie (np. ścianie wydobywczej),
-  hierarchiczny monitoring i ocena stanu wielu różnych procesów, które decydują o ruchu, czy bezpieczeństwie kopalni.

Tego typu działania, w których możemy skorzystać z komunikacji głosowej, czy multimedialnej zmieniły w sposób niezwykły obraz dzisiejszej kopalni. Uważamy, że to istotne kroki na drodze do stworzenia zautomatyzowanej eksploatacji podziemnej złóż, w której nastąpi znaczne ograniczenie ilości załogi dołowej szczególnie zaś w rejonach zagrożonych.

Mamy świadomość trudności jakie przed nami stoją, ale też już nieraz okazywało się, iż to właśnie górnictwo i jego skrajne techniczne warunki środowiskowe podziemi kopalń, to najlepszy obszar dla różnego rodzaju innowacyjnych działań i eksperymentów.

To właśnie tej problematyce poświęcona jest niniejsza monografia. To pierwsza publikacja Szkoły Eksploatacji Podziemnej poświęcona zagadnieniom telekomunikacji, monitoringu i wizualizacji procesów produkcyjnych w kopalniach, stanowiąca podsumowanie jednej z najważniejszych sesji Dwudziestej Jubileuszowej Szkoły Eksploatacji Podziemnej. Wierzymy, że rozpoczyna ona kolejny interesujący etap w naszych działaniach.

The monograph discusses telecommunications dispatching systems operated in mines, the process of their development, the current state of safety parameter monitoring systems as well as telephone communication systems and alarm-broadcast communication systems (chapter 2). General principles of integration of telecommunication systems were presented. On the basis of the analysis of the current state, problems related to the hardware and software integration of security and alarm systems were presented. (chapter 3). On the example of gasometric and alarm broadcasting systems, the method of technical implementation of dispatcher telecommunication systems previously functioning as autonomous systems has been presented. Signal transmission methods, information exchange protocols, communication software, databases and system operation algorithms were analyzed.
The next chapter discusses the issues of reliability of selected dispatch systems. The elements of the theory of reliability as applied to the evaluation of these systems were presented. The paper presents the results of research on the metrological reliability of methane sensors as the lowest level of the system and the reliability of data transmission between the systems. The expected improvement in the reliability of the integrated system (in relation to individual systems) was estimated on the basis of the reliability assessment of the dispatcher obliged to send an alarm signal to the endangered area after receiving an alarm signal from the gasometric system.

W październiku ukazała się nowa edycja monografii "Geomatyka Górnicza - Praktyczne zastosowania". Monografia zawiera rozdziały, które zostały przygotowane na bazie dyskusji prowadzonych przez uczestników Szkoły Eksploatacji Podziemnej w 2009 i w 2011 roku.

Do monografii dołączono również teksty nie związane bezpośrednio z konferencją, jednak prezentujące bardzo ciekawe rozwiązania geoinformatyczne wdrażane obecnie w krajowym górnictwie.

Warto podkreślić, że stopniowe zwiększanie zaangażowania polskich zakładów górniczych w skanowanie laserowe spowodowało podjęcie decyzji przez organizatorów Szkoły Eksploatacji Podziemnej o zorganizowaniu panelu dyskusyjnego "Skanowanie Laserowe w Górnictwie" w ramach Sesji Geomatyki Górniczej.

Niniejsza publikacja jest kontynuacją serii wydawniczej Szkoły Eksploatacji Podziemnej. Wyselekcjonowane do monografii artykuły prezentują praktyczne zastosowanie absolutnie najnowocześniejszych geomatycznych technik pomiarowych i prezentacyjnych stosowanych w polskim górnictwie. W monografii omówiono zastosowanie nowoczesnej technologii pomiarowej – skanningu laserowego do pomiarów wyrobisk górniczych oraz pomiary deformacji terenu i obiektów przemysłowych za pomocą technologii GPS. W monografii znajdziemy również informacje o pierwszych pomiarach deformacji skarp zakładów odkrywkowych pomierzonych za pomocą technologii naziemnej interferometrii radarowej. Niewątpliwe najbardziej rozbudowaną częścią monografii są rozdziały poświęcone zastosowaniu naziemnego skaningu laserowego (Terrain Laser Scanning) do skanowania wyrobisk podziemnych zakładów górniczych. W pierwszym rozdziale monografii przedstawiono 3 podstawowe kierunki wykorzystania technologii skanowania laserowego w zakładzie górniczym: skaning maszyn i obiektów w celu realizacji projektu ich przebudowy, skanowanie nietypowych zjawisk geologicznych (zjawisko np. krasowe w kopalni podziemnej), które ułatwia skartowanie tego typu form, oraz skanowanie wyrobisk podziemnych w celu ich inwentaryzacji i wykonania pomiarów deformacji. W kilku następnych rozdziałach znajdziemy kolejne przykłady wykorzystania technologii skaningu laserowego w górnictwie. W zakresie technologii pomiarów GPS obserwujemy również intensywny postęp w uzyskiwaniu coraz większych dokładności pomiaru. Umożliwia to zastosowanie GPS – RTK do pomiarów niecek obniżeniowych czy też tworzenia systemów ciągłego monitoringu wież szybowych zakładów górniczych. W monografii nie zabrakło opisu najnowszych technologii oraz wdrożeń oprogramowania w zakładach górniczych. W jednym z rozdziałów przestawiono technologię Xaris przeznaczoną do modelowania i prowadzenia obiektowych map górniczych. PoWstęp GEOMATYKA GÓRNICZA – SZKOŁA EKSPLOATACJI PODZIEMNEJ 2013 7 zawala ona prowadzić mapy wyrobisk górniczych od razu w środowisku bazy danych przestrzennych z trójwymiarową geometrią. Zaprezentowano również doświadczenia z wdrażania technologii serwerowej do obsługi map górniczych oraz nowe oprogramowanie dla geologów. Wydanie tej edycji monografii potwierdza, że nasze działania związane z popularyzacją geomatyki górniczej znalazły już szerokie grono zainteresowanych pracowników nauki i przedstawicieli przemysłu. Sesja Geomatyki stała się jednocześnie forum ciekawych oraz twórczych dyskusji. Dyskusji w której pragnęlibyśmy aby czynny udział brali nie tylko geodeci górniczy czy szerzej pracownicy działów mierniczo-geologicznych polskich kopalń węgla kamiennego i rud metali, ale także przedstawiciele pozostałych branż przetwórstwa surowców mineralnych oraz przedstawiciele samorządów gmin górniczych.

W środowisku naukowym - ale i szerzej - w świadomości ogółu społeczeństwa olbrzymią popularność zrobiło pojęcie zrównoważonego rozwoju (sustainable development), po raz pierwszy zdefiniowane w 1987 roku w raporcie „Nasza wspólna przyszłość", opracowanym przez Światową Komisję Środowiska i Rozwoju Organizacji Narodów Zjednoczonych. W raporcie tym zrównoważony rozwój zdefiniowany został jako proces mający na celu zaspokojenie aspiracji rozwojowych obecnego pokolenia w sposób umożliwiający realizację tych samych dążeń następnym pokoleniom. Jednocześnie ze względu na wielość i różnorodność czynników, mogących wpływać na to zjawisko, wyodrębniono trzy główne obszary, na których należy skoncentrować się przy planowaniu skutecznej strategii osiągnięcia zrównoważonego rozwoju. Są to:
- ochrona środowiska i racjonalna gospodarka zasobami naturalnymi,
- wzrost gospodarczy i sprawiedliwy podział korzyści z niego wynikających,
- rozwój społeczny.
Patrząc na wyodrębnione powyżej obszary z perspektywy sektora górniczego, można powiedzieć, iż zrównoważony rozwój w branży wydobywczej polega na takim gospodarowaniu zasobami złóż kopalin, aby w efekcie końcowym prowadzona działalność była efektywna ekonomicznie, przyjazna dla środowiska oraz akceptowalna społecznie.
Badania zrealizowane przez autora w ramach podjętego tematu pracy doktorskiej są opisane w następującym układzie:
- W rozdziale drugim autor prezentuje analizę stanu zagadnienia, któremu poświęcił swoje badania. Zakres analizy, zarówno merytoryczny jak i objętościowy, wymagał ograniczenia się do wybranych metod modelowania matematycznego w ramach teorii projektowania kopalń, a w zasadniczej mierze do metod analitycznych, metod wariantów lub też metod kombinowanych z zastosowaniem komputerowej techniki obliczeniowej.
- W rozdziale trzecim autor definiuje tezę, wytycza cel oraz przyjmuje odpowiednią metodykę pracy.
- Rozdział czwarty obejmuje opis stosowanych w kraju klasyfikacji zasobów z uwagi na jakość kopaliny. Zawiera charakterystykę kryteriów przemysłowości zasobów z naciskiem na przypomnienie obowiązujących definicji strat i zubożenia kopalin, kluczowych dla procesu analizy wpływu zanieczyszczenia na efektywność prowadzonego procesu wydobywczego.
- W rozdziale piątym autor analizuje przyczyny powstawania zanieczyszczenia urobku w procesie eksploatacji węgla kamiennego, rozpoczynając swoje wywody od analizy wpływu na powstawanie zanieczyszczenia takich elementów, jak: struktura udostępnienia złoża, ilość skały płonnej, warunki geologiczno-górnicze zalegania złoża, technika i technologia eksploatacji złóż węgla.
- W rozdziale szóstym autor poddaje ocenie wpływ zanieczyszczenia urobku na efektywność ekonomiczną procesu produkcyjnego podziemnego zakładu górniczego. Bazuje ona na odpowiednich danych, które pochodziły z trzech przodków ścianowych zlokalizowanych w pokładzie cienkim kopalni LW .Bogdanka" S.A., będących w różnych fazach procesu wydobywczego. Dane empiryczne poddano analizie statystycznej ukierunkowanej na opracowanie modelu matematycznego postępu ścian w zależności od struktury jakościowej i ilości urobku pochodzącego z analizowanych przodków strugowych. Stosując symulację metodą Monte Carlo oraz analizę skupień i analizę scenariuszową, opracowano model matematyczny stanowiący podstawę do analizy efektywności ekonomicznej procesu wydobywczego w scenariuszach zakładających poprawę jakości urobku.
- W rozdziale siódmym autor opisuje własną koncepcję automatyzacji i monitoringu procesu produkcyjnego, którą wdrożył w LW Bogdanka S.A., a na którą składa się kilka wzajemnie ze sobą połączonych komponentów. Jest ona wynikiem doświadczeń zbieranych podczas realizacji dużych projektów badawczych dla KGHM Polska Miedź S.A., JSW S.A. i Tauron Wydobycie.
- W podsumowaniu (rozdział 8) autor przedstawia najważniejsze spostrzeżenia i wnioski wynikające z przeprowadzonych badań.

This book aims to present an alternative based on natural processes and an environmental approach to post-excavation site management, e.g., post-coal mining heaps. These sites are places where various minerał excavation by-products are collected. Nevertheless, some post-mineral excavation sites are oligotrophic, terrestrial, wetland, and water habitat islands, providing unique biodiversity enrichment in the landscape. These oligotrophic minerał habitats are essential in over-fertilized, eutrophic, agricultural and urban-industry surroundings. Some post-mineral excavation sites are places where the wildlife can develop and support the functional processes of novel ecosystems. Implementing the newest biogeochemical and comprehensive knowledge into urban-industry landscape management will help to establish the ecosystenYs processes and environmental functioning.
There are several post-industrial sites in Europę where the wildlife areas developed due to natural processes, are becoming wildlife hotspots in densely populated urban-industry areas. In this respect, many of the oligotrophic minerał terrestrial, wetland, and water habitats of anthropogenic origin should not be categorized as environmentally dangerous and undergo economic utility-focused reclamation.
Facing the actual environmental constraints of the Anthropocene Epoch, the book's chapters presenting the natural basics and perquisites ofthe environmental ecosystem mosaics, will be interesting for a broad rangę of environmentalists (scientists and students), miners, economists, and sociologists.

The objective of the book is to demonstrate the up-to-date Polish and intemational experience in the area of thin coal seam mining. The implementation of the plow technology in Poland is done by young engineers for whom the automated extraction system presents itself as a great challenge pinpointing the direction of future developments - a production mining face manned by a skeleton crew, fully utilizing the potential offered by the information technology. They create new ways and means of running the production processes, which are successfully used together with the new generation plows. Successive generations of young mining engineers entering their careers are equipped with a new type of ability and. most of all, awareness which is characterized by a new understanding of reality, in which “real" is what is on the screen. They are the guarantee that this direction of research and the drive towards
minimizing human involvement in the underground production chores will receive inereasing focus and will remain the area of development. The expcriences to-date of three mines (KWK Zofiówka, KWK Jas-Mos, LW Bogdanka S.A.) show that there is a real potcntial for the Polish companies to join in the research aimed at developing new plow installations. This publication is to sum-up the actions-to date taken both in Poland and all over the world in terms of implementing the plow technology in mining.

This monograph is a summary of the Author’s studies carried out on the development of a deep mine model, taking into account specific nature of natural conditions and the requirements of safe, and at the same time economically efficient mining of hard coal deposit in the Lublin Coal Basin at big depths. The conception of an IT system construction, presented in the final part of the monograph, assumes an automatic calculation of the quantity and quality of the ROM and dirt in selected time slots, and after a completion of the simulation an automatic forecast generation of all the parameters related to the implemented mining project, such as the ROM quantity, amount of dirt and coal qualitative parameters. The research work carried out by the author, as regards those issues, is described in this Monograph in the following arrangement:
− In Chapter 2 the Author presents the analysis of the state of the issue, to which he devoted his research. It starts from a description of resources classifications, used in the country, taking into account the quality of minerals and characteristics of commercial nature of resources, emphasising a recollection of the binding definitions of mineral losses and dilution, crucial for the analysis of the dilution impact on the efficiency of carried out mining operations.
− In Chapter 3 the Author analyses the reasons for the ROM dilution origination in the process of hard coal mining, starting the considerations from the analysis of such elements as the structure of deposit opening, the amount of dirt, geological-mining conditions of beds deposition, and the technique and technology of coal deposits mining impact on the origin of dilution.
¬ In Chapter 4 the Author performs an assessment of the ROM dilution impact on the economic efficiency of an underground mining plant production process. It is based on the appropriate data, which originated from three longwalls situated in a thin seam of the LW Bogdanka SA mine, being in various phases of the mining process. The empirical data were subject to the statistical analysis directed towards developing a mathematical model of longwall advance depending on the quality structure and amount of the ROM originating from the analysed plough faces. With use of the Monte Carlo simulation and also of the cluster analysis as well as the scenario analysis a mathematical model was developed, being the basis for an analysis of the economic efficiency of the mining process in the scenarios assuming an improvement in the ROM quality.
¬ In Chapter 5 the Author describes his own concept of the production process automation and monitoring, which he implemented in the LW Bogdanka SA, consisting of a few interconnected components. It results from the experience gathered during an implementation of big research projects for the KGHM Polska Miedź S.A., and Tauron Wydobycie S.A. The Integration Platform is a central element of the presented solution, being a significant tool for the information integration, allowing a standardised exchange of data among systems built in various technologies, or using various communication protocols.

The project of implementing roof bolting support in the mines of Jastrzębska Spółka Węglowa S.A. (Jastrzębska Coal Company J.S.C), presented on the pages of this Monograph, aimed at a signicant efficiency increase of driving roadway workings. In the result of it, a technology of conducting mining operations with use of bolting in the system of continuous cutting and a support installation, appropriate for the conditions of deep, gassy mines of coking coal, was elaborated and implemented.
Cutting-and-bolting machines of the Bolter Miner type are commonly used in the world hard coal mining industry. They are widely used for driving and supporting roadway workings, however in room-and-pillar systems of mining they can be also used for conducting exploitational operations.
An implementation of independent bolting support in the system of continuous cutting and supporting, realized by the JSW S.A., undoubtedly is an innovative attempt of adapting this technology to difficult conditions of the Upper Silesian Coal Basin and longwall mining systems.
The project was realized in the Budryk mine over a period of 13 months, during which 1168 meters of the Bw-1n test roadway located at the depth of about 900 m, were driven. A realization of the project showed that the technology of driving workings in independent bolting technology was safe and the driven working was stable. Besides, the operations, executed by the mining teams, directly in the working under drivage, were less arduous than in the case of traditional support.
The project confirmed a possibility of using independent bolting suport driven with use of cutting-and-bolting machine of the Bolter Miner type in the conditions of the JSW S.A. mines, which was its main objective.
The obtained measurable advantage for the project participants consisted in gaining experience in using state-of-the-art mining technologies in the Polish conditions.
A realization of the project was a source of new experience for all the consortium participants due to its unique character and type of conducted mining operations. It should be highlighted that despite many attempts of implementing independent bolting support in Polish mines in the past, the project can be treated as a pioneer solution in the Polish hard coal mining industry. An attempt of conducting a roadway working, supported with independent bolting support with use of specialistic 12CM30 Bolter Miner cutting-and-bolting machine, was undertaken for the first time.
The project was and it still is a reaction of the JSW S.A. to the challenges awaiting the whole Polish mining industry in the closest years and it should be a valuable inspiration in the scope of its further transformation.
A supplementary component of this Monograph is the Annex containing the photographic documentation of the realized project “Independent Bolting Support” at the JSW.

Monografia prezentuje zdobyte przez zespoły badawcze doświadczenia
związane z wdrożeniem powszechnie stosowanej na świecie technologii drążenia wyrobisk korytarzowych z wykorzystaniem samodzielnej obudowy kotwowej wykonanej za pomocą kombajnu urabiająco-kotwiącego typu Bolter Miner w warunkach głębokich kopalń węgla koksowego JSW S.A. Wdrożenie to było realizowane w ramach projektu „Samodzielna Obudowa Kotwowa” przez Jastrzębską Spółkę Węglową S.A. w kopalni „Budryk” przez okres 13 miesięcy, podczas których wydrążono 1 168 m metrów chodnika Bw-1n badawczego zlokalizowanego na głębokości ok. 900 m. Wykazano, że technologia wykonywania wyrobisk w samodzielnej obudowie kotwowej jest bezpieczna, a wydrążone wyrobisko jest stateczne. Ponadto prace wykonywane przez załogi górnicze, bezpośrednio w drążonym wyrobisku, były mniej uciążliwe niż w przypadku obudowy tradycyjnej.
Badawczo-rozwojowy charakter projektu pozwolił na przeprowadzenie
szeregu analiz, wypracowanie najlepszych praktyk w drążeniu wyrobiska oraz nabycie cennego doświadczenia ruchowego w takich kwestiach jak:
− dobór optymalnego układu maszyn i urządzeń wyposażenia przodkowego,
− projektowanie samodzielnej obudowy kotwowej,
− praktyczne wykonywanie obudowy kotwowej w warunkach głębokich
kopalń metanowych,
− dobór optymalnych materiałów eksploatacyjnych,
− monitoring wyrobisk korytarzowych w samodzielnej obudowie kotwowej.
Prowadzone prace potwierdziły zasadność analizy wyników badań
kierunków maksymalnych naprężeń poziomych przy projektowaniu wyrobisk w samodzielnej obudowie kotwowej, w szczególności przy projektowaniu kierunków rozcinek nowych pól eksploatacyjnych.
Realizacja drążenia chodnika odbywała się przy ciągłym monitoringu
górotworu. Monitoring górotworu, poza pomiarami konwergencji, realizowany był także za pomocą kamery introskopowej. Na określonych odcinkach wyrobiska zlokalizowano stacje kontroli okresowej, na których za pomocą kotew oprzyrządowanych, ekstensometrów, sond ekstensometrycznych oraz rozwarstwieniomierzy dwu- i trójpoziomowych, mierzono w warunkach in-situ zmiany rozwarstwień i działających sił. Odpowiednie wartości rozwarstwień  sygnalizowały konieczność podjęcia działań w celu wzmocnienia górotworu lub ewakuacji załogi.
W monografii zaprezentowano:
− genezę powstania kombajnu Bolter Miner,
− historię stosowania obudowy kotwowej w górnictwie krajowym i na świecie,
− opis samego projektu wdrożenia samodzielnej obudowy kotwowej
w wyrobiskach korytarzowych kopalń JSW S.A.,
− analizę pełnego spektrum możliwości zastosowania przedmiotowej
technologii w procesie drążenia wyrobisk udostępniających i przygotowawczych, a także w wybieraniu resztkowych partii złoża,
− opis parametrów górniczo-geologicznych i zagrożeń naturalnych
występujących w rejonie wykonywanego wyrobiska,
− opis wykonania obudowy kotwowej dla chodnika Bw-1n badawczego (wraz z kontrolą stanu i monitoringiem),
− analizę wykonywania przez kombajn Bolter Miner zakrętów podczas
drążenia chodnika,
− analizę postępów i ocenę efektywności prowadzonych robót górniczych.

On the anniversary of the disaster in the Zofiówka mine, where five miners died after a strong shock on May 5, 2018, current activities aimed at improving safety in JSW mines were presented.

The collapse in the Jastrzębie mine, caused by a strong rock mass shock, occurred on Saturday, May 5 before noon. After the earthquake, seven miners working 900 m underground were searched for. Rescuers reached two of them after a few hours, they were injured. The rest did not survive the accident - the body of the last of the searched workers was found by rescuers on the 11th day of the rescue operation conducted in extreme conditions. It ended on May 19 - within two weeks, a total of approximately 2.5 thousand people participated in the action.

The implementation of innovative solutions to improve miners' safety are the most important recommendations of two expert teams appointed by the president of JSW, Daniel Ozon, after the disaster. After analyzing the rescue operation, the teams identified solutions that would improve employee safety and facilitate possible rescue operations. Hence, among others decision to establish and appropriately equip the JSW central rescue warehouse in Zofiówka.

In addition, the team prepared recommendations to improve the operation of mine rescue stations. This concerns, for example, the work of rescuers in a four-shift system and their equipment, among others. with modern thermal imaging equipment or other equipment for scanning workings. Additionally, traffic dispatchers will have at their disposal a system enabling simulation of changes in the mine's ventilation - this will facilitate the rescue operation in its first stage. After the experience from the rescue operation in Zofiówka, a decision was made to start testing new rescue devices and select the best ones for JSW rescuers.

The second team of experts worked on developing guidelines for improving communication standards, identification and monitoring of workers staying underground. Recently, JSW has chosen a technology that will monitor miners in real time - a solution based on the radio signal measurement method (RSS), which was the best during the tests. 170 km of optical fibers and 242 km of radiating cable were purchased to build the system.

The Polish-Australian ties in the mining industry result from several very obvious facts about areas in which Australia is the undisputed world leader:
production efficiency
production quality
strategic planning and pragmatic approach for mining

In addition, Australia and Poland are mining countries, and given current perspectives, it will remain so for a quite a long time

The goals for JSW considering Polish-Australian cooperation are :
learn from the best and the greatest
both look for new challenges
find  the best solutions for polish mining conditions
creation of international partnership in the area of research and development

The DIGITAL TRANSFORMATION of Poland's key raw material consortium  on the one hand allowed for  the implementation of strategic efficiency programmes such as QUALITY and EFFICIENCY,  but what is equally important, it allowed for the elimination of the huge technological debt with  which Jastrzębska Spółka Węglowa S.A. has been dealing with it basically since its  establishment in 1993 and in the subsequent years of its operation.
This debt, growing year by  year, strangled the technological innovativeness of the JSW S.A., especially in the years  2000÷2015, paralyzing the implementation of advanced IT projects and not recognizing the OT area at all, the implementation of which could have significantly improved the production  monitoring and control processes in the JSW mines.

In 1996, during the sessions of the 5th School of Underground Mining - the largest mining conference in Poland, a book entitled "Exploitation of thin hard coal seams" was published. It was a summary of one of the sessions, which was attended by authors from several countries dealing with this issue.
After that, she came back to it several more times. At that time, there were appeals for a change in the approach to thin seams and not abandoning the search for the technique and technology of their exploitation - at that time they accounted for over 30% of the balance resources and almost 30% of the industrial resources. In the foreword of this publication, it was written: “The search for new technologies for the exploitation of thin seams remains the main task in the coming years. Extensive international cooperation will significantly increase the chances of success of this search. Let's hope it comes to that, and our meeting will be one of its tiny links."
Organized at LW "Bogdanka" S.A. the conference - the eleventh in the series of the International Mining Forum - aims to show the current Polish and global achievements in the field of mining thin hard coal seams.
In Poland, the implementation of the plow technique is carried out by young engineers, for whom the automated mining system is a real challenge indicating the direction of further development - it is mining with minimal human participation in the face with a new role and opportunities
information technology. They create new forms and ways of handling the production processes carried out so far, perfectly and successfully used in the new generation of plowing technology. Successive generations of young personnel entering the mines, endowed with a new type of skills and, above all, awareness characterized by a special understanding of reality (reality is primarily what is on the screen) guarantee that this direction of searching for new solutions and striving for the smallest number of people employed on the the bottom of the mines will be increasingly developed.
The previous experience of three mines (KWK "Zofiówka", KWK "Jas-Mos", LW "Bogdanka" S.A.) shows that there are real opportunities for Polish companies to become involved in the further development of further plow installations.
We believe that this conference will be a perfect summary of the activities undertaken so far in Poland and in the world in the field of implementing plow technology in mining.

Сегодня, характерной особенностью развития цивилизации является ускорение научно-технического прогресса и экономического развития стран. Это сопряжено с увеличением использования энергетического сырья. Соответственно, обеспечение их достаточности (особенно невозобновляемыми источниками энергии) является весьма актуальной проблемой. Этому способствует тот факт, что в XX веке, общемировой промышленный потенциал вырос в более чем десять раз. После второй мировой войны расход энергетического сырья достиг уровня соответствующего суммарного использованию этих источников за всю историю человечества [1]. Решение вопросов энергетического обеспечения сопровождает человечество на протяжении всей истории его развития. Это вытекает из роли, которую сырьё играет в развитии цивилизации [2]. Исходя из вышесказанного, необходимо развивать всякую деятельность, направленную на оптимизацию эффективности и полноты выемки месторождений. По мнению авторов, одним с таких направлений является построение информационных систем содействия разработки запасов. Создание такой системы при подготовке запасов на лучшей угольной шахте Польши «Богданка», внедряемого авторами в производство совместно с PRGW (обществом с ограниченной ответственностью по выполнению геологических и бурильных работ), стало основой для написания этой статьи.

One of the factors determining the growth in demand for coking coal is steel consumption and the volume of production in countries with low consumption rates and the highest population, with a high development potential compared to developed countries. In general, Asia is increasingly affecting the global market, being the largest producer and thus the largest consumer of raw materials for its production. It should be noted that in 2010, steel production in China represented about 44% of global production, and in 2020 this share grew to 58%. In the same period, Europe had, respectively 12% share in world steel production in 2010 and, in 2020 less than 8%. In the pandemic year 2020, world steel production fell by less than 1%, but this was mainly due to a 1.6% increase in Asia because other regions of the world saw significant declines, e.g. the European Union by nearly 12%. In Poland, steel production fell at the same rate as the European average, namely also by approx. 12%
In the coking coal market, business cycles typically last from one to several years, with varying price movements and production growth rates.  shows the volatility of the benchmark and spot coking coal price quotations from January 2016 to January 2021. In Q4 of 2021, Australian coking coal prices have significantly exceeded US$ 200/t, an increase of nearly US$ 100 per tonne since the beginning of the year.
In March 2020, the developing 2020 global SARS Covid-19 pandemic caused a very large increase in coking coal prices in key markets. The coke market, which is heavily dependent on the steel industry, suffered severely from the reduction in global production. This is particularly evident in the automotive sector in Europe. Among the steel-consuming sectors, the automotive sector was hardest hit by the Covid-19 pandemic. New car registrations in the EU fell at a record pace in 2020 – nearly 24%, and it is the largest drop in new car registrations since such statistics began. All major car markets in the EU saw double-digit declines. The other key steel-consuming sector, i.e. construction, was less affected as projects were mostly ongoing but with significant increases in material prices. Now, after a period of declining coking coal prices and production in the second half of 2021, global economies have started to accelerate, and production rates have returned to pre-pandemic levels. The complement to the current business cycle is certainly the ongoing trade war between China and Australia, in which China appears to be emerging as an insurmountable power, as evidenced by the performance of the Chinese economy. China’s crude steel production reached a record of over 1 billion tonnes in 2020, which is a result that is more than 5% higher than in 2019. China’s economy grew by 2.3% in 2020, making it the only major global economy to achieve positive growth in a year of pandemics presented in Fig. 3. Metallurgy, an industry that is the pillar of China’s economic growth, performed better than expected and steel prices rose for most of 2020; whether this trend will be permanent will be decided by China through its administrative decisions on steel production or raw material import policies and the scenario that the Covid-19 pandemic will determine in the future

The strategy of Jastrzębska Spółka Węglowa to use its own energy sources to meet the demand by 2030.
The Jastrzębska Spółka Węglowa SA is the biggest coking coal and coke producer in Poland and in the entire European Union. Mining plants are situated in southern Poland, in the Upper-Silesian Coal Basin. The basic business of the company consists in the production and sales of hard coal, mainly coking coal, and the production and sales of coke and by-products. The maintaining of coal and coke production on the quantitative and qualitative level required by the customers is a crucial issue for the company.
The production of hard coking coal and related customer requirements in terms of a high and stable product quality force the entrepreneur to forecast its specifications based on the in situ (in the deposit) tests of the raw material, prior to its mining and getting to the surface. Before 2015 JSW SA mining plants carried out forecasts independently, based on traditional methods of flat (2D) digital mining and geological maps, which were updated usually once a few months, or even in longer time periods. The instability of coal quality parameters was then treated as natural, related to the variability of quality parameters of coal deposits.

Jastrzębska Spółka Węglowa is the largest producer of high-quality type 35 (hard) coking coal and the leading producer of coke in the European Union in terms of production volume. The Group's mining area is located in the Upper Silesian Coal Basin. Approximately 44% of coking coal produced in JSW's mines is processed by the Group's coking plants. The main product is blast furnace coke, which, next to iron ore, is the basic component of the input for steel production in steel mills.
JSW is the largest producer of coking coal and the largest producer of coke in the European Union:
-  5 hard coal mines, in 2016, produced 16.8 million tonnes of coal,
-  4 coking plants, in 2016, produced 4.1 million tonnes of coke. It is the largest commercial group of coking plants in the European Union (mainly a producer of blast furnace coke).
Our mines have a total of approx. 6.228 billion tons of coal balance resources, including approx. 0.993 billion tons of recoverable coal resources.
We restructured the debt - agreement with JSW S.A. Bondholders (new bond redemption schedule - extension of the redemption period by 5 years, i.e. until 2025).
We redeem our bonds in a timely manner in accordance with the mandatory redemption schedule and fulfill other obligations under the Agreement, including information obligations, on an ongoing basis.
We improved the asset and capital structure and liquidity position, e.g. through the resignation by the Bondholders of their rights under the so-called put option, understood as the possibility of early redemption of bonds

Effective implementation of new market strategies faces the mining enterprises with new challenges, which require precise assessment instruments of the carried out business to be met at the level of mines, preparation plants, coking plants, and steelworks. These instruments include deposit, technological, and economic parameters, which together with a safety margin, determining a percentage reserve level of each parameter, shape the profitability of undertaken projects.
The paper presents the course and obtained implementation effects of a unique system for the production line management in the capital group of the Jastrzębska Spółka Węglowa (JSW) SA. The developed system allows optimizing the effectiveness of the production process in the system of one carried account within the entire mining group, which consists of mining plants together with preparation plants and coke plants. In particular, the paper raises the effectiveness issues of the system for deposit modeling and mining production scheduling in a multi-plant enterprise.
The heuristic technical architecture of the JSW S.A. production line management system, presented in the paper, allows to analyse the production process profitability in a carried account system in the area of mines, preparation plants, and coking plants of the mining group of the biggest European coal producer for metallurgical purposes.
The assumptions related to the construction of a system being in the future a basis for the realization of the Mine 4.0 idea are discussed.

The Jastrzębska Spółka Węglowa SA is the largest coking coal and coke producer in Poland and the entire European Union. The mining plants are located in southern Poland, in the Upper Silesian Coal Basin. The basic business of the company consists of the production and sales of hard coal (mainly coking coal), coke, and by-products. Maintaining coal and coke production at the quantitative and qualitative level required by customers is a crucial issue for the company.
The main issue consists of obtaining and maintaining the specified qualitative parameters of the coking coals required by the customer. Therefore, the issues of quality of coking coal can be considered both from the point of view of customers and producers. From a technological point of view, the quality parameters of coking coal determine the practical value of coal for the customers, i.e., its usability in the coking process, and for the producers - the technological regime appropriate to ensure the parameters of saleable coal required in the contracts. At the same time, the quality parameters decide about the production costs of finished products for customers, while for producers - about the obtained sale prices and incurred costs of concentrates production (Blaschke, 2009). Because of that, it is necessary to plan the mining in such a way as to be able to mine the coal with the required quality parameters, so that it does not lie in piles and wait for sale. The issue of coking coal quality is also perceived in other countries, where it is also a subject of scientific research. The Czech corporation OKD already in 2013 presented the effects of its studies on that (Danel et al., 2013). Analyzes have shown the need to integrate the measurement laboratory software into an integrated IT system that supports the sales of coal and coke. Scientists in Russia started studies on the coordination of coal coking coal mining by 8 mines (including an open-cast) to improve the quality parameters of the raw material (Berkutov, 2020). In the years 2018 and 2019 Russian mining plants improved and stabilized the quality parameters via the reorganization of raw material supplies.
In the past, the coking coal and coke market strongly affected JSW SA, and the company did not have any tools to prevent it. Therefore, actions were taken to build a modern production planning and scheduling system, driven by demand and quality (Demand and Quality Driven Management System).

The activities of the JSW Group related to corporate social responsibility are carried out in accordance with international standards. The basis for activities in the field of CSR is the "Strategy of Sustainable Development until 2020. Its assumptions combine 25 years of experience and modern challenges facing a modern enterprise.
The activities of the JSW Group make a significant contribution to the development of the Polish and European economy. It employs nearly 32,000 employees, thus directly and indirectly supporting socio-economic development.
Particular care for the local environment is a showcase of the JSW Group's approach to sustainable development. The JSW Group could not focus solely on the natural environment and ignore the social environment. The local community has been the focus of JSW's attention for years. It is also the focus of activities in the form of extensive social engagement programs. The first step in building long-term relationships with the local community is to eliminate, and where possible, to reduce, the negative impact. First of all, it is about mining damage. On the one hand, it means basing relations with communities on dialogue and the accompanying openness. It is also a commitment to take their views into account in the decision-making process, in situations where the decisions made may affect these communities. It also means mining planning in a way that will minimize the scale of mining damage and the obligation to repair or pay compensation for the resulting damage.
From a managerial point of view, compensating communities for the nuisances associated with the operation of plants, which can neither be eliminated nor reduced, is crucial. It focuses primarily on the areas where the JSW Group conducts its business activity and which it has an impact on. So far, the activities carried out were in the form of charity aid (mainly the JSW Foundation), proprietary social programs (JSW), and were also related to the support of sports (JSW). The JSW Group implements both long-term proprietary social programs (JSW KOPALNIA WIEDZY or JSW KIDS) and charity activities, and is also a patron of sport.
The Congress i san unique opportunity to gather together representatives of national and European politicians with managers of the largest companies in the Energy and mining sector as well as experts and scientists. There will be created a field for discussion on the current vision of climate and Energy policy, the importance of fuels in the context of national energy security but also as an element fueling the technological development of many other branches. At the same time the Congress will show innovative undertakings and Solutions serving the society and environment.

The Smart Mine Program is a response to the natural need to increase competitiveness and increase the degree of development of the hard coal mining sector in Poland through the successive introduction of new technical and technological solutions.
The Smart Mine, due to the export potential of combining innovative technological solutions with the experience and knowledge of industry practitioners conducting underground mining of hard coal in the most difficult conditions, was included as a project in the Strategy for Responsible Development and is included in the Program for Silesia. In the history of the Polish underground mining sector, attempts have already been made to define the scope, purpose and optimal formula for the implementation of the Smart Mine project. JSW Innowacje S.A. in this study presented a new approach, the aim of which is to increase the efficiency of the mining process, and to improve the level of safety and work comfort of mining crews.
These goals will be achieved mainly by stimulating the investment processes carried out in the mines of the JSW Group using tools limiting the investment risk.

Jastrzębska Spółka Węglowa is the largest producer of high-quality type 35 (hard) coking coal and the leading producer of coke in the European Union in terms of production volume. The Group's mining area is located in the Upper Silesian Coal Basin. Approximately 44% of the coking coal produced in JSW's mines is processed by the Group's coking plants. The main product is blast-furnace coke, which, apart from iron ore, is the basic component of charge for the production of steel in steelworks. Other types of coke produced are used in foundries, in the non-ferrous metals industry, in the chemical industry and in the production of insulating materials. In 2012-2016, as a result of the decrease in the prices of steel, coke and coal, the economic and financial situation of the JSW Group deteriorated significantly. The effects of the declines lasting for several years were visible on the market in the form of e.g. low utilization of steel production capacity, stopping mining in mines, or closing or limiting the production capacity of coking plants. In response to the difficult situation of the steel and coal sectors, there was a deep restructuring, consolidation and sale of assets in the thermal and coking coal sectors around the world and in Poland. The above also affected the JSW Capital Group. In 2016, the JSW Group Restructuring Program for 2016-2025 was developed and implemented. The main restructuring activities specified in the Program focused on the following activities:

- debt restructuring, reaching an agreement with the social side to reduce labor costs,
- transferring unprofitable assets of the JSW Group to SRK,
- reducing operating costs to the necessary minimum,
- disposal of assets to improve and restore JSW Group's financial liquidity,
- adjusting the capital structure to the level of forecasted cash flows.

In 2016-2017, as part of restructuring activities at JSW S.A., the following optimization measures were undertaken:

- Savings initiatives – during the implementation of the Programme, a number of savings initiatives were defined,
- the total assumed effect of which in 2016-2025 was estimated at PLN 1.6 billion. Increase in employee productivity – an increase in the volume of coal produced per employee (jointly JSW S.A. and JSW SIG Sp. z o.o.) was achieved, which in 2016 amounted to 710 tonnes/employee (in 2015, 631 tonnes/employee).
- As a result of savings measures in the operating area, the unit cash cost of coal extraction (MCC) ratio was reduced by approximately 18%, i.e. from 307.10 PLN/t in 2015 to 251.38 PLN/t in 2016.

Jastrzębska Spółka Węglowa jest największym producentem wysokiej jakości węgla koksowego typu 35 (hard) i wiodącym producentem koksu w Unii Europejskiej pod względem wielkości produkcji. Obszar wydobywczy Grupy ulokowany jest w Górnośląskim Zagłębiu Węglowym. Około 44% węgla koksowego produkowanego w kopalniach JSW przetwarzane jest przez koksownie wchodzące w skład Grupy. Głównym produktem jest koks wielkopiecowy, który obok rudy żelaza stanowi podstawowy składnik wsadu do produkcji stali w hutach. Pozostałe rodzaje produkowanego koksu wykorzystywane są w odlewniach, w przemyśle metali nieżelaznych, przemyśle chemicznym i przy produkcji materiałów izolacyjnych. W latach 2012-2016, w wyniku spadków cen stali, koksu i węgla, sytuacja ekonomiczno- -finansowa Grupy Kapitałowej JSW uległa znacznemu pogorszeniu. Skutki trwających od kilku lat spadków były widoczne na rynku w postaci m.in. niskiego wykorzystania mocy produkcyjnych stali, wstrzymania wydobycia w kopalniach, czy też zamknięcia lub ograniczenia mocy produkcyjnych koksowni. W odpowiedzi na trudną sytuację sektora stalowego i węglowego, nastąpiła głęboka restrukturyzacja, konsolidacja i wyprzedaż aktywów w sektorze węgla energetycznego i koksowego na całym świecie oraz w Polsce. Powyższe nie ominęło także Grupy Kapitałowej JSW.
JSW jest przekonana, że wykorzystanie najnowszych technologii to właściwy kierunek, który nie tylko zapewni GK JSW optymalny rozwój, ale również wyznaczy trend dla całego górnictwa. W Grupie JSW utworzono Jastrzębskie Centrum Innowacji i Rozwoju (JSW Innowacje S.A.) spółkę, która ma być kompleksowym zapleczem badawczo-rozwojowym całej Grupy Kapitałowej Jastrzębskiej Spółki Węglowej. Swoją działalnością JSW Innowacje obejmować ma wszystkie fazy działalności badawczo-rozwojowej Grupy Kapitałowej, od badań, przez projekty, ocenę oddziaływania na środowisko, analizę wykonalności, po nadzór nad ich realizacją. Działania innowacyjne będą dedykowane różnym obszarom - wydobyciu, przeróbce węgla, koksownictwu, obszarowi ochrony środowiska oraz nowych technologii. Jednym z podstawowych elementów nowej Strategii Grupy Kapitałowej JSW będzie digitalizacja procesów produkcyjnych oraz technologicznych w obszarze wydobycia i produkcji koksu. JSW Innowacje S.A., poza zwiększeniem efektywności w obszarach wydobycia węgla 33 i produkcji koksu, pracować będzie m.in. nad nowoczesnymi rozwiązaniami dotyczącymi zagospodarowania zasobów i odpadów oraz innowacyjnych rozwiązań w rewitalizacji terenów poprzemysłowych w obrębie Grupy JSW.

The update of JSW Capital Group’s business strategy, prepared since the beginning of 2020, whose aim is primarily to provide the safety and continuity of the Group’s production, led to the adoption of the Company’s necessary regulations preventing the mines from filling up with coal stored above the level safe for the mining plant’s operation and to secure itsstrategic storage sites so that, if necessary (for example, when rail traffic stops due to the pandemic), it will be possible to safely deposit the coal extracted by the mines at a time when the mines’ storage sites are dangerously close to 75% fill. All these activities implemented in the area of production volume optimization: ongoing analysis and monitoring of production capacity, research and forecasting of quality and sales opportunities based on the demand of the internal and external markets (exports and domestic sales), along with the establishment of the new Quality Management Office, made up the ”Product Quality Strategy for the JSW Capital Group for 2020–2030” adopted by the Management Board and the ”Quality Management Policy for Deposit and Product Testing in the JSW Capital Group” enabling assurance of the desired level of qualitative parameters of coking coal and steam coal, as well as the rules for forecasting the level of qualitative parameters of steam coal

JSW Group's Program and Project Management Methodology is the key to effective implementation of the strategy in the mining industry In modern corporate structures The business strategy is subject to constant revision and updating, depending on many exo- and endogenous factors. The presentation discussed m.in the expectations of stakeholders and their impact on the shape of the implemented strategy – scientific approach vs. the perspective of top management. The presentation is devoted to the subject of implementation and inclusion of environmental projects in business strategies of companies. It addresses the issues of how environmental projects build the strategic value of organizations and how organizations have changed their approach to the implementation of environmental projects. Methods of measuring the impact of implemented projects using dedicated tools were presented. The changing environment and the dynamic development of new technologies also force dynamic reactions in organizations. The presentation answers the question whether modern enterprises are able to keep up with these trends, for example thanks to the use and use of modern tools supporting broadly understood management in organizations.

The Jastrzębskie Centrum Innowacji i Rozwoju (JSW Innowacje S.A.) was established in the JSW Group, which is to be a comprehensive research and development base for the entire Jastrzębska Spółka Węglowa Group. JSW Innowacje is to cover all phases of the Group's research and development activity, from research, through projects, environmental impact assessment, feasibility analysis, to supervision over their implementation. Innovative activities will be dedicated to various areas - mining, coal processing, coking, environmental protection and new technologies.
One of the key elements of the JSW Group's new Strategy will be the digitization of production and technological processes in the area of coke mining and production. In addition to increasing efficiency in the areas of coal mining 33, 34 and coke production, JSW Innowacje S.A. will work m.in on modern solutions for resource and waste management as well as innovative solutions in the revitalization of post-industrial areas within the Group.

Jastrzębska Spółka Węglowa was established 25 years ago. Learning  about history means not only memorising dates, figures, and names,  but first of all understanding and accomplishing the action goals formulated by the founders.  That is how history lives in us and actually we learn about it for this  purpose.
Jubilees are always fine, when they do not finish anything, at the  same time the greatness of the past cannot close us in yesterday – we must move forward – exactly as it sounds in an old English proverb: ‘time stays, we go’. It seems that our today reality is just such; we  must be active all the time.
The 25-year history of Jastrzębska Spółka Węglowa is the evidence  of great determination in striving for a common good, being the  mines, in maintaining the jobs for nearly 24,000 persons, in seeking  organisational improvements, contributing to the improvement in  the work effectiveness and conditions. The respect for work, solidarity, the strength of character are an invaluable contribution brought  by the employees of mines in building the value of Jastrzębska Spółka Węglowa.
The period of past 25 years witnessed thorough technical, economic,  organisational, and technological restructuring as well as laying foundations for the increase in productivity and for the costs cutting. That  was a period of creating one of most modern hard coal companies  in Europe. The successes of recent years undoubtedly resulted from  many years of work of a huge mass of employees

Jastrzębska Spółka Węglowa and LW "Bogdanka" strongly focus on digitization. Both leading coal producers in Poland use the MineScape system, which is one of the parts of the Intelligent Mining Systems (IMS) package. Digital support in the field of deposit modelling, work scheduling and planning the production process brings real benefits to mines.

The system is used by 4 out of 6 largest mining companies in the world. It is used primarily to create a geometric and qualitative model of the deposit. In other words, the system suggests whether it is worth starting mining in this particular place or not. This is of great importance in planning costly investments. Both "Bogdanka" and JSW SA, which is currently implementing the world's largest system implementation, have already had their first experience with the basic ABB MineScape module.

The future of industry is digital – also of the mining industry, which for a long time has had a fairly conservative approach to new technologies. And digital deposit modeling is usually the first step towards computerizing planning and production processes.

In order to meet the ever-increasing quality requirements of contractors and the requirements in the area of environmental protection, the JSW Group implements the necessary development and modernization investments in the area of coking coal and coke production.
The above action will be implemented in the JSW Group, taking into account the following factors:
- Impact on the environment - technology: one of the most important factors for the future operation of the company. It is necessary to modernize or replace coke batteries that do not meet the standards of legal regulations related to the impact of the installation on the environment, including regulations on technique, technology, monitoring of substance and energy emissions (the so-called BAT conclusions).
- Cost position - cost effectiveness is crucial in case of fluctuations in the Company's revenues, resulting from cyclical changes in coke prices, as well as market demand for its products.
- Product quality - customers' trust in the supplier in terms of meeting the agreed contractual conditions is an important element in building proper commercial relations.
Providing a product of the required quality can be an important factor in the process of building a strategic competitive advantage.

Effective implementation of new market strategies faces the mining enterprises with new challenges, which require precise assessment instruments of the carried out business to be met at the level of mines, preparation plants, coking plants, and steelworks. These instruments include deposit, technological, and economic parameters, which together with a safety margin, determining a percentage reserve level of each parameter, shape the profitability of undertaken projects. The paper raises the issues of designing an IT architecture of the system for deposit modelling as well as the mining production scheduling, implemented in the JSW S.A. The development and application of the system was important from the point of view of the overriding objective of the Quality Programme of the JSW Capital Group, that is increasing the effectiveness of deposit and commercial product quality management. The paper presents next the developed required specification of the technical architecture, necessary to implement systems as well as the required actions necessary to integrate with other IT systems of the JSW Group. The heuristic technical architecture of the JSW S.A. production line management system, presented in the paper, allows to analyse the production process profitability in a carried account system in the area of mines, preparation plants, and coking plants of the mining group of the biggest European coal producer for metallurgical purposes.

JSW is the largest producer of high-quality coking coal and the main independent producer of coke in the European Union.
The JSW Group supplies coking coal and coke mainly to the largest European steel companies, and also to overseas markets for coke.
Most European steelworks using the blast furnace coke process operate within 500 km.
The significant potential for growth in sales of coking coal of the JSW Group is indicated by the level of coking coal imports to the EU.
Overseas markets allow for the diversification of the coke sales market
Steelworks in the EU use approximately 37 million tons of coke in the blast furnace process (blast furnaces + sinter plants), for the production of which approximately 53 million tons of coking coal are consumed annually (without PCI).
Despite ongoing research into direct reduction or use of hydrogen in the steel production process, the level of coke and coal consumption in the EU will remain stable.
The prospect of widespread use of new technologies in the European steel industry is distant and limited (technologically and economically).

JSW (Jastrzebska Spolka Węglowa) is the largest coking coal producer in the EU. The company extracts coal from four existing mines and a fifth one is presently under construction. Together these hold one billion tonnes of recoverable resources, which can guarantee a production until the year 2075. JSW employs more than 30.000 people, which makes it one of the biggest employers in Poland.

The strategy revolves around maintaining leadership in coking coal production in Europe. We find ourselves in a favorable position now that coking coal has been listed among the EU Critical Raw Materials, hence it has a vital impact on the European economy.

"The European Union has historically been and will remain in a structural shortage of coking coal, which is why it is a major importer of this raw material."

Currently, among all EU countries only Poland produces coking coal (about 11 million tons per year) together with Czech Republic (about 1.5 million tons in 2018) which is expected to shut down production soon. The demand from the steel industry exceeds mining capacity of EU countries by approx. 40 million tons.

In the Krupiński mine we can extract methane as the main mineral, we estimate that over 800 million m3 are trapped in this deposit methane. There are currently six engines operating in the mine that burn this gas and generate electricity. Our task now is to model an effective technological system that will allow us to precisely determine how long it will be possible to obtain methane and under what conditions it will be profitable economically.
Another concept is the construction of a modern logistics center. To begin with, we plan to use the infrastructure of the JSW Material Logistics Plant located in the Krupiński mine for this purpose. In the future, we want to build a large logistics center in Suszec serving the entire Polish-Czech border region.
Suszec is located in an attractive location, close to the A-1 and A-4 motorways. In my opinion, this location should be taken advantage of, JSW is ready to build such a center within two years from the moment of making the investment decision. We are currently talking to the best
logistics specialists in the country who are to prepare a preliminary feasibility study of such a project.

It was a double celebration. During the holy mass in the "Na Górce" church in Jastrzębie, the Laudato Si' Mobile Embassy was launched, and the JSW Foundation announced the official start of its operations.
The Mobile Embassy promotes pro-ecological activities in accordance with the teachings of the Catholic Church. This is an electric Mercedes Benz/Automet bus, which was lent to Caritas Polska by Spółka Węglowa from Jastrzębie. The president of the management board of JSW, Daniel Ozon, handed over a symbolic ownership deed to the electric bus in October last year. Now the vehicle has arrived in Silesia, where it will travel around parishes, promoting pro-ecological attitudes among residents under the slogan of "ecological awakening" - referring to the papal encyclical "Laudato Si"!

- After a difficult 2019, when the steel sector in Europe recorded deteriorating financial results and struggled with complex geopolitical, economic and environmental problems, in general 2020 did not bring the expected improvement - notes Dr. Eng. Artur Dyczko, acting President of JSW, Vice-President for Technical and Operational Affairs, summarizing the last year. Recall that COVID-19 lockdowns have resulted in severe reductions in steel production around the world, although unevenly and not at the same time.
- The pandemic determined the level of demand and raw materials for its production, including coking coal and coke, which are the main JSW products. Unfortunately, no one could have predicted this pandemic, says Artur Dyczko. He adds that subsequent lockdowns were announced quickly, and as a result, steel production in the world stopped or was significantly limited.
- The situation in the second quarter was particularly severe in India, where steel mills operated at less than 50 percent capacity. of its capacity, as well as in Europe, where 18 out of 80 installed blast furnaces were turned off - reminds the vice-president of JSW.

Steel without carbon? - The development of new, more ecological steel production technologies is a natural process in the pursuit of reducing emissions into the environment. We are monitoring the progress of various projects regarding new steel production technologies, including the use of hydrogen or gas - mainly in the direct iron reduction process. However, these are still pilot projects and the industrial scale is still a long way away, says Dr. Eng. Artur Dyczko, acting president of JSW, vice-president for technical and operational affairs, reminding that such technologies are currently very expensive.
- Commercialization of such processes will not be economically profitable for a long time for various reasons. In the case of technologies using hydrogen, it is primarily its price, as well as the properties of hydrogen, which pose a significant challenge from the point of view of its storage and transport, and so far this problem has not been solved. In turn, direct reduction requires the use of very high-quality iron ore, explains the vice president.
The supply of such ore is limited and for now, as the COYID-19 pandemic has shown, blast furnace technology based on coke and coking coal is the most economically and technically effective steel production technology.

– For us, it is not only about beautiful photographs of people who passionately capture breakthrough moments in the life of the company and its employees.
For me, the chronicling value is equally important, because the presented photographs are testimony to history, said Artur Dyczko, president of the JSW Foundation, which has supported the "Niezależnych" project from the beginning.

Additional brigades were assigned to work in the new mine. Thanks to this decision, approximately 900 m will be excavated this year
more excavations than planned. Previously, the excavation of approximately 320 m of sidewalks was accelerated by five months. The first wall in the mine will be approximately 200 m long and have a 700 m runway.
There will be approximately 250,000 to choose from. tons of high-quality coking coal. Its launch is scheduled for St. Barbara's Day 2021.
Another wall, with a runway of approx. 1.3 km and resources of approx. 435 thousand. tons of coal, is scheduled to launch in mid-2022.

In the years 2019–2022, JSW will allocate approximately PLN 600 million for the construction of a new mine, and by 2033 the total expenditure may reach PLN 3 billion.
Ultimately, the mine is to extract approximately 2 million tons of coal per year.
The Jastrzębie-Bzie mine will exploit coal from two mines parts of the Bzie-Dębina deposit. They contain almost 180 million tons of operational raw material resources. About 95 percent it is high-quality coking coal.

– Despite the complications caused by the pandemic, we are implementing our investment plans. In times of prosperity, we saved money in a special fund intended for difficult times. We are taking advantage of the savings and preparing the Company for the return of economic prosperity, says Vice-President Artur Dyczko.

Over the past few years, each year on average PLN 8-10 billion was transferred from Jastrzębska Spółka Węglowa to the region's economic system. This is money spent on wages, investments, services, fees and taxes. For wages only (including taxes charged employer) the company spends on average approximately PLN 3.5 billion each year.
– The vast majority of this money remains in place.
Please imagine the economy in JSW's immediate surroundings
in a situation where it suddenly loses such an injection of money, when approximately PLN 10 billion disappears from circulation every year. The Management Board of JSW focuses on development because it is aware of the Company's importance for the region, he says vice-president Dyczko.

Dyczko: November 11 - Independence Day and broadly understood freedom - is an ideal opportunity to remember the 40th anniversary of the Jastrzębie Agreement, which we celebrate in 2020. On that day, at 11 a.m., in the church dedicated to the Blessed Virgin Mary, Mother of the Church in Jastrzębie-Zdrój, there will be a Holy Mass for the Homeland, and at 4 p.m., a theater performance will take place -musical "Heroism of Witold Pilecki".
Forty years ago, miners from the Jastrzębie mines achieved the impossible. Freedom and justice were the ideas of great national uprisings, intended for heroes looking at them from history books. They came to the Jastrzębie mines from all over Poland. They came with hope for a better future and they never let that hope be taken away from them. It was she who pushed them to the first strikes in 1980. Thanks to it, the Jastrzębie Agreement guaranteed a better life for everyone, not only mining families.

In the next 10 years, the Jastrzębska Spółka Węglowa Capital Group wants to focus almost entirely on coking coal, achieve energy self-sufficiency, develop the resource base and continue the modernization of the coking plant. The Group's strategy, updated at the beginning of this year, also assumes consistent implementation of innovations and new technologies, while maintaining full financial stability and employment stabilization. To effectively implement the strategy's assumptions, JSW focused on project management. The idea is to precisely monitor and verify the level of achievement of individual goals at each stage.
– The strategy should not only talk about what is to be achieved at the end, but also indicate how we want to achieve it. The key are the goals indicated therein. Currently, we have 10 of them, and each goal should be "smart", i.e. fully measurable and verifiable - he explains.
Vice-president of JSW for technical and operational affairs, Artur Dyczko, who three years ago inspired the implementation of a new program and project management methodology in the company, based on the so-called project management. Its introduction in the JSW Group radically changed the way of verifying the implementation of the strategy and, at the same time, improved its management. The essence of the innovative approach is to focus on specific projects that are the key to achieving the goals, and thus the entire strategy. – If, for example, we have a goal related to energy self-sufficiency, then thanks to the fact that we implement four key projects within this goal, we know how close or far we are from achieving it. Similarly, with respect to the remaining goals - each of them is defined in individual projects, the implementation of which we monitor at every stage. Project management is what allows us to verify the effectiveness of our actions, explains the vice president.

Deputy Minister of State Assets Artur Soboń, government plenipotentiary for the transformation of energy companies and coal mining, met on October 8, 2020 with the management board of Jastrzębska Spółka Węglowa and representative trade union organizations. The problems of the Polish mining industry and the importance of JSW for the economy were the main topic of the meeting.
Dyczko: Jastrzębska Spółka Węglowa captures over one third of the methane that escapes from underground mines. Much of it is used to produce energy. However, the possibilities and needs are much greater. The company announces investments in methane drainage from mines and gas development.
– Our fuel is a side effect of our core business, i.e. mining of coking coal. Just support
JSW's investments to capture this gas at all stages of mining activity and we have a huge ecological and, at the same time, economic effect.
If methane were introduced into the European emissions trading system, it would cost us approximately PLN 637.5 million, because the greenhouse potential of methane, which accompanies coking coal deposits, is as much as 28 times greater than the greenhouse potential of carbon dioxide - explains Artur Dyczko, deputy president of the management board of JSW for technical and operational.

October 14 at the Primary School. Mikołaja Rej, a modern computer laboratory with a terminal type was opened in Gorzyczki. The IT equipment is a gift from the JSW Foundation. It consists of a server, 15 terminal workstations, 10 laptops and a large-format monitor instead of a whiteboard. The facility also received ergonomic chairs and desks from the foundation. The value of the donation is almost PLN 50,000. zlotys.
– Supporting education is one of the most important statutory goals
JSW Foundation. For us, it is not only an investment in the youngest generation, but also an investment in our common future.
So far, we have supported the creation of 15 specialized school laboratories in institutions throughout the region. Today, we are opening a workshop in Gorzyczki where students will acquire knowledge of computer science and foreign languages, competences that will determine not only their education, but also probably their entire professional future - said Artur Dyczko, president of the JSW Foundation.

C0VID-19. Almost 40.5 thousand smear tests. About 3.9 thousand confirmed cases of coronavirus infection. There is one piece of information missing from the statistics that attract journalists' attention: 23,000. saved jobs at Jastrzębska Spółka Węglowa. However, they are excited about a possible prosecutor's investigation against those who did not decide to close the mines and wait for the epidemic to end. A pandemic has engulfed the Earth and it is not known whether and when we will fight the plague.
There was enormous hate against the miners. "Close the mines", "Surround the source of the plague with a cordon sanitaire". Enemies of mining particularly liked the idea of restructuring the industry through plague. - This is a good excuse to close the mines - entries with such a message, sometimes laced with profanity, began to appear on the Internet, and we have done everything possible to protect miners against infection - says Vice President Dyczko.

Jastrzębska Spółka Węglowa and the JSW Foundation launched a campaign under the slogan "STOP HATE! Don't slander a miner!" against discrimination against people associated with mining and residents of Silesia. The ambassador of the campaign is a well-known footballer, a native of Jastrzębie - Kamil Glik.
Out of concern for its employees, their families and the local community, Jastrzębska Spółka Węglowa, through the JSW Foundation, has decided to launch the "STOP HEJTO! Don't slander the miner", whose main task will be to change the attitudes of the society towards the inhabitants of Upper Silesia, and miners in particular. The campaign was joined by people from the world of sport, film, television and music, who are associated with the region and the mining community, including Justyna Święty-Ersetic, European champion in the 400 m run, members of the cabarets Kabaret Młodych Panów and Łowcy. B, the band Feel with its leader Piotr Kupicha, the music trio Frele.
The main problem in stopping the wave of hatred lies in society's lack of understanding of the nature of miners' work. - We stood up for our employees and their families. They constitute the value of the company, so our task is to provide them with a safe and stable place of work and life - says Artur Dyczko, president of the JSW Foundation and vice-president for technical and operational matters, at the same time head of the Crisis Staff of JSW SA

The coronavirus pandemic is hitting all industries and from many sides. Lock down and closure of production plants is one source of the decline in production, but the other is a decline in demand including energy and steel. Some analysts, however, indicate that the need to reduce costs while rebuilding the economy after the pandemic may again increase the attractiveness of coal.
ARTUR DYCZKO: - At JSW we do not fight the virus because we are not doctors. We defend ourselves against it, we learn to live and work in dangerous conditions. I appeal: do not share the virus. Share knowledge about preventing infection.

In 2019, Jastrzębska Spółka Węglowa will invest well over PLN 2 billion. These are record expenses in the history of the Company. In order to spend such a large amount rationally, preparations have been going on for three years. They started when the last crisis in the mining industry was still going on. - Our line of defense against a cooling economic situation are efficiency, work safety and increased productivity - says Artur Dyczko, vice-president for strategy and development of JSW SA.

Jastrzębska Spółka Węglowa. It is known what cutting-edge solutions are used in deep-sea mining by the best global companies. It was no secret to anyone in the management at JSW that they would one day have to be used in the Company. However, too often there was a lack of faith that the time was right and decisions were postponed.

Oases of modernity are not enough. Outstanding professionals working alone are a thing of the past. Thinking in terms of a month, a quarter or a year will not allow you to create stable foundations for development. The world is rushing and JSW has a choice - stand still or join the mainstream.

IT at JSW is to perform the same function as the Central Information Processing Center at KGHM. The famous KGHM COPI is the only organizational unit for the copper giant dealing with IT and IT security.
KGHM COPI has a similar status in the production line as a mine, processing plant, smelter or copper rolling mill. It is an important element of the ore-concentrate-metal production process.
– This is the essence of the change we are introducing at JSW. IT and automation are also to be an important element of our process
technological coal-coke. I would like IT to be at a high level during this period, but for it to be in the background, even unnoticeable. For example, we have become accustomed to applications on smartphones. They are already a kind of natural environment. IT is expected to be equally natural at JSW. It is supposed to help at every step and work on the "you need - you have" principle. It's not about the miner walked around wearing gadgets, but it was important that he had immediate access to the necessary information - explains Vice President Dyczko.

In 2017, the JSW Capital Group achieved a net profit of PLN 2,543.3 million compared to PLN 4.4 million in 2016. - Such good financial results are the result of favorable coking coal prices, optimization activities and consistent implementation of the restructuring program - the Company announced in its official statement. message.
At JSW, we are preparing to model the deposit in 3D. Thanks to it, we will know exactly what quality of coal can be expected in the deposit. This is not a solution that will be operational within a quarter or two. It's probably a matter of a few years. We are moving in this direction in small steps. Then, well in advance, before the next part of the deposit begins to be exploited, we will be able to precisely determine the coal parameters

The goal for JSW is precisely defined: to focus on coking coal mining, take advantage of the good situation on global markets, strengthen its position and ensure conditions for stable development in changing economic conditions.
The JSW Capital Group will spend approximately PLN 19 billion on investments by 2030. PLN 16 billion of this will go to mines. Without these investments, it will not be possible to achieve the planned goals. From 2020, the share of coking coal in total production will be 85%.

The strategy adopted by JSW is the result of the work of a large team of employees of the JSW Capital Group. It is endorsed by the management board. Vice-president Artur Dyczko is directly responsible for it.
- This is not the result of my genius or infallibility. My success is that I managed to convince wonderful employees and specialists to believe in the meaning of their work and be willing to share their knowledge.

Jastrzębska Spotka Węglowa has been working intensively for several months on transforming the JSW Capital Group into a project organization. This is a great success for the JSW management board and employees, because thanks to their determination and great commitment, the work was not wasted.
- We focused on development and innovation because this is the only way to ensure that we will be competitive in the difficult global coking coal market in the future. From the very beginning, we also knew that the strategy implementation process must be monitored and fully scalable, which is why, in parallel with building the strategy, we developed our own project management, strategic management and standardization methodology, an approach that, in my opinion, ensures full integration of the stages of planning, implementation and monitoring of the strategy - explains Artur Dyczko, deputy president of the JSW management board for strategy and development.

In West Alpine, the meetings began with an analysis of the epidemic situation in Jastrzębska Spółka Węglowa. The Pniówek and Zofiówka mines were the main points of interest of our contractors. We answered numerous questions after each piece of information from JSW that might have worried our recipients. They calmed down when we assured that the supplies were not at risk, says Artur Dyczko, vice-president of JSW SA. Fulfilling contracts and maintaining over 30,000 jobs is the success of the Company's staff, who responsibly and in a disciplined manner followed the recommendations of the JSW Crisis Staff.
W West Alpine narady zaczynały się od analizy sytuacji epidemicznej w Jastrzębskiej Spółce Węglowej. Kopalnie Pniówek i Zofiówka były głównymi punktami zainteresowania naszych kontrahentów. Odpowiadaliśmy na liczne pytania po każdej informacji płynącej z JSW, która mogła zaniepokoić naszych odbiorców. Uspokajali się, kiedy zapewnialiśmy, że dostawy nie są zagrożone - mówi Artur Dyczko, wiceprezes JSW SA. Wywiązywanie się z umów i zachowanie ponad 30 tys. miejsc pracy to sukces załogi Spółki, która odpowiedzialnie i w sposób zdyscyplinowany stosowała się do zaleceń Sztabu Kryzysowego JSW.

Dyczko: Even the bravest miner will not be able to survive at a level of, for example, 1 300 meters without the support of air conditioning, work automation and computerization of mining processes. JSW will not be able to maintain the coking plant if it does not limit its negative impact on the environment. No way out. We need to go into green technologies. - The concepts being prepared for implementation do not serve to satisfy the ambitions of any of the management board members.
I have heard opinions that we will not be able to sustain our company on hydrogen, that buses powered by hydrogen cells will not save the company, and that computerization of technological processes will not replace miners. Yes, it's all true. However, without green technologies, we will fail economically. We will pay fines, which are now called emission permits or emission fees. The so-called greens will mark our image as a polluter, says Artur Dyczko, vice president for strategy and development of JSW SA.
Jastrzębska Spółka Węglowa. Nawet najdzielniejszy górnik nie wytrzyma na poziomie na przykład 1 300 metrów bez wsparcia klimatyzacji, automatyzacji pracy i informatyzacji procesów wydobywczych. JSW nie da rady utrzymać koksowni, jeżeli nie ograniczy ich negatywnego wpływu na środowisko. Nie ma wyjścia. Trzeba iść w zielone technologie. - Przygotowywane do realizacji koncepcje nie służą zaspokojeniu ambicji któregokolwiek z członków zarządu.
Spotykałem się z opiniami, że z wodoru nie utrzymamy firmy, że autobusy napędzane przez ogniwa wodorowe nie uratują Spółki, a informatyzacja procesów technologicznych nie zastąpi górników. Tak, to wszystko prawda. Jednak bez zielonych technologii padniemy ekonomicznie. Będziemy płacić kary, które teraz nazywa się pozwoleniami na emisję albo opłatami za emisję. Tak zwani zieloni wypalą na naszym wizerunku piętno truciciela - mówi Artur Dyczko, wiceprezes ds. strategii i rozwoju JSW SA.

JSW STRATEGY. Effective coal mining, modernization of coking plants and energy self-sufficiency - these are the most important goals for the entire JSW Capital Group. These goals cannot be achieved without implementing innovative solutions. - If we do not come up with new solutions and implement them, in 10 years we may have problems with keeping the company on the market, because we will not have solved the basic problem: how to effectively and safely extract coal lying deeper than 1,000 meters underground? - says Artur Dyczko, vice president of JSW SA for strategy and development.
STRATEGIA JSW. Efektywne wydobycie węgla, modernizacja koksowni i samowystarczalność energetyczna - to najważniejsze cele dla całej Grupy Kapitałowej JSW. Nie można osiągnąć tych celów bez wdrożenia innowacyjnych rozwiązań. - Jeżeli nie wymyślimy nowych rozwiązań i ich nie wdrożymy, to za 10 lat możemy mieć problem z utrzymaniem firmy na rynku, bo nie rozwiążemy podstawowego problemu: jak efektywnie i bezpiecznie wydobywać węgiel zalegający głębiej niż kilometr pod ziemią? - mówi Artur Dyczko, wiceprezes JSW SA do spraw strategii i rozwoju.

The coal sector has been front and centre in the climate change debate since the last COP meeting in Paris, in 2015, with several high-profile mining company investors exiting registers – or pledging to do so – unless firms take drastic carbon emission reduction measures.
This has seen Rio Tinto gradually sell off its entire coal portfolio and other miners, such as Anglo American and Glencore, agree to curb thermal coal output. BHP is also weighing a thermal coal exit, according to the latest reports from Bloomberg.
It is ironic that the sector bearing the brunt of climate change activism is also one of the leaders when it comes to technological innovation.

JSW’s Artur Dyczko says the company’s recent research visit to Australia “was aimed at seeing a practical demonstration of the application of modern longwall production systems together with their remote monitoring, in the Australian mining environment, as systems significantly improving efficiency which may be potentially used in JSW’s conditions”

Zlokalizować górnika, uratować życie  - zapadła decyzja Zarządu Jastrzębskiej Spółki Węglowej SA o rozpoczęciu prac nad wyborem i wdrożeniem systemu służącego identyfikacji i lokalizacji załogi w strefach szczególnie zagrożonych.

Przypomnijmy: 5 maja o godzinie 10.58 na poziomie 900 (rejon  H, pokład 409) nastąpił silny  wstrząs górotworu. Kiedy po  11-dniowej, niezwykle trudnej akcji  ratowniczej, na powierzchnię wydobyto ostatnią, piątą ofiarę, Zarząd JSW uznał, że nie można dłużej zwlekać i podjął szereg działań  zmierzających do poprawy bezpieczeństwa pracy.

Decyzja Zarządu Jastrzębskiej Spółki Węglowej SA (JSW) o rozpoczęciu prac nad wyborem i wdrożeniem systemu służącego identyfikacji i lokalizacji załogi w strefach szczególnie zagrożonych jest to konsekwencją ubiegłorocznej katastrofie w KWK „Borynia-Zofiówka-Jastrzębie” Ruch „Zofiówka” (maj 2018).

Jednym z największych wyzwań dla prowadzących akcję ratowniczą było wtedy właśnie zlokalizowanie górników.

3D measurements are a reality in Jastrzębie's mines - the JSW Management Board has set itself the goal of modernizing management and design processes in mines. The Company is carrying out several projects, including 3D deposit modeling and production scheduling. All projects require a huge commitment of mine surveying and geological departments and, of course, the purchase of modern equipment. After earlier purchases of modern total stations, now the surveyors from JSW received handheld scanners.
- The process of digitization and computerization of the production line conducted by JSW is directly related to equipping the surveying and geological departments with new equipment. We must remember that in the conditions of the mine and the management of the mining process, the production preparation phase is crucial for its rationality and relevance. It means collecting the necessary information about the nature of the selected deposit, especially factors limiting exploitation. The process of digitization and computerization is included in the strategy until 2030 in the Quality and Efficiency programs - said Artur Dyczko, Vice-President of the JSW Management Board for Strategy and Development.

Dyczko: - Prowadzony przez JSW proces cyfryzacji i informatyzacji ciągu produkcyjnego wiąże się wprost z doposażeniem działów mierniczo-geologicznych w nowy sprzęt - musimy pamiętać, że zebranie niezbędnych informacji o charakterze wybieranego złoża, zwłaszcza czynnikach ograniczających prowadzenie eksploatacji jest kluczowe dla opłacalności naszego biznesu.
POMIARY 3D TO RZECZYWISTOŚĆ W JASTRZĘBSKICH KOPALNIACH - Zarząd JSW postawił sobie za cel unowocześnianie procesów zarządzania oraz projektowania w kopalniach. W Spółce prowadzonych jest kilka projektów, między innymi modelowanie złoża 3D i harmonogramowanie produkcji. Wszystkie projekty wymagają ogromnego zaangażowania kopalnianych działów mierniczo-geologicznych i co oczywiste, zakupu nowoczesnego sprzętu. Po wcześniejszych zakupach nowoczesnych tachimetrów teraz mierniczy z JSW otrzymali skanery ręczne.
- Prowadzony przez JSW proces cyfryzacji i informatyzacji ciągu produkcyjnego wiąże się wprost z doposażeniem działów mierniczo-geologicznych w nowy sprzęt. Musimy pamiętać, że w warunkach kopalni i zarządzania procesem wydobycia faza przygotowania produkcji ma kluczowe znaczenie dla jej racjonalności i trafności. Oznacza ona zebranie niezbędnych informacji o charakterze wybieranego złoża, zwłaszcza czynnikach ograniczających prowadzenie eksploatacji. Proces cyfryzacji i informatyzacji jest zapisany w strategii do roku 2030 w programach Jakość i Efektywność - powiedział Artur Dyczko, zastępca prezesa zarządu JSW ds. strategii i rozwoju.

JSW IT SYSTEMS. The IT company Advicom solemnly celebrated its twentieth anniversary. The name change process is in progress. Now it is JSW IT Systems. The name is changing, the number of tasks is increasing, but the strategic importance of the IT company for JSW has not changed. IT in mining plants is primarily monitoring, control and control of the main production systems. It is also the ability to control combine harvesters, switchgears, ventilation, haulage, supervision over the safety of people's work. A modern mine needs perfect connectivity, location, automation and finally IT. - IT as a background is to be at the service of our highly qualified miners, geologists, surveyors, electricians, mechanics, processors and coke makers. The word "service" is the key to opening the door to the digital revolution at JSW – emphasizes Artur Dyczko, Vice-President of JSW SA, in an interview with Nowy Górnik.

Dyczko: Górnictwo ma innowacje w kodzie genetycznym - Informatyka jako tło ma być na usługach naszych wysoko wykwalifikowanych górników, geologów, geodetów, elektryków, mechaników i koksowników. Słowo „usługa" jest kluczem do otwarcia drzwi dla rewolucji cyfrowej w JSW.

JSW IT SYSTEMS. Spółka informatyczna Advicom uroczyście obchodziła dwudziestolecie istnienia. Trwa proces zmiany nazwy. Teraz to już JSW IT Systems. Zmienia się nazwa, przybywa zadań, ale niezmienne jest strategiczne znaczenie spółki informatycznej dla JSW. Informatyka w zakładach górniczych to przede wszystkim monitoring, sterowanie i kontrola głównych systemów produkcyjnych. To także możliwość sterowania kombajnami, rozdzielniami, wentylacją, odstawą, nadzór nad bezpieczeństwem pracy ludzi. Nowoczesna kopalnia potrzebuje perfekcyjnej łączności, lokalizacji, automatyzacji i na końcu informatyki. - Informatyka jako tło ma być na usługach naszych wysoko wykwalifikowanych górników, geologów, geodetów, elektryków, mechaników  i koksowników. Słowo „usługa” jest kluczem do otwarcia drzwi dla rewolucji cyfrowej w JSW - podkreśla w rozmowie z Nowym Górnikiem Artur Dyczko, wiceprezes JSW SA.

Methane is a deadly threat to miners. It is possible that soon it will also become dangerous for European mining. In the European Union, we hear more and more often about plans to include emissions of this gas in the European Emissions Trading System (ETS).
The Management Board of Jastrzębska Spółka Węglowa is analyzing the possible impact of the penalty charges on its condition. We conduct constant, active monitoring of legislative processes in Brussels. JSW implements economically justified projects aimed at increasing the economic use of methane. Taming this dangerous gas is profitable for both the Company and the environment.

Metan jest śmiertelnym zagrożeniem dla górników. Możliwe, że już wkrótce stanie się również niebezpieczny dla europejskiego górnictwa. W Unii Europejskiej coraz częściej słyszy się o planach włączenia emisji tego gazu do europejskiego systemu handlu emisjami (ETS).
Zarząd Jastrzębskiej Spółki Węglowej analizuje możliwy wpływ karnych opłat na jej kondycję. Prowadzimy stały, aktywny monitoring procesów legislacyjnych w Brukseli. JSW realizuje ekonomicznie uzasadnione projekty mające na celu zwiększenie gospodarczego wykorzystania metanu. Ujarzmianie tego niebezpiecznego gazu jest opłacalne zarówno dla Spółki, jak i środowiska naturalnego.

Employees of the mining industry are people living in the world of technology, a world clearly marked in liters, kilograms or kilometers. When they start running projects, they have to negotiate, assess the likelihood of what will happen, manage risk. They are usually not prepared for this. For a year, classes at the Academy of Project Management in Industry also teach them these competences.
On January 27, over 100 managers from PGG, JSW and KGHM summed up the year-long cooperation as part of the Academy of Project Management in Industry, organized by IPMA Polska (International Project Management Association). The Academy is a joint initiative of Jastrzębska Spółka Węglowa, Polska Grupa Górnicza and KGHM Polska Miedź.
Why is it so important to improve project management skills? Because while expensive investments are the driving force behind the development of companies, the key to managing them are high-class specialists and a unique management method that allows for maximum creativity and efficiency.

Pracownicy branży górniczej to ludzie żyjący światem techniki, światem wyraźnie oznaczonym litrami, kilogramami czy kilometrami. Kiedy zaczynają prowadzić projekty, muszą negocjować, oszacować prawdopodobieństwo tego, co się wydarzy, zarządzać ryzykiem. Zwykle nie są do tego przygotowani. Od roku zajęcia Akademii Zarządzania Projektami w Przemyśle uczą ich także tych kompetencji.
27 stycznia ponad 100 menedżerów z PGG, JSW i KGHM podsumowało roczną współpracę w ramach Akademii Zarządzania Projektami w Przemyśle, zorganizowanej przez IPMA Polska (International Project Management Association). Akademia jest wspólną inicjatywą Jastrzębskiej Spółki Węglowej, Polskiej Grupy Górniczej i KGHM Polska Miedź.
Dlaczego tak ważne jest doskonalenie umiejętności zarządzania projektami? Ponieważ o ile kosztowne inwestycje są kołem zamachowym rozwoju firm, o tyle kluczem do zarządzania nimi są z kolei wysokiej klasy specjaliści i unikalny sposób zarządzania, który pozwala na maksymalną kreatywność i efektywność.

Ten biznes ma sens. O specyfice „Strategii 2018-2030” dla Grupy Kapitałowej JSW Solidarność Górnicza rozmawia z zastępcą prezesa Zarządu Jastrzębskiej Spółki  Węglowej SA (JSW) do spraw strategii i rozwoju Arturem Dyczko.
Solidarność Górnicza:-Panie prezesie, 9 lutego w siedzibie warszawskiej Giełdy Papierów Wartościowych Zarząd JSW przedstawił założenia "Strategii 2018-2030 z uwzględnieniem Spółek Zależnych Grupy kapitałowej JSW". Czym ten dokument różni się od innych strategii spółek węglowych, z jakimi do tej pory mieliśmy do czynienia? Aartur Dyczko, zastępca prezesa Zarządu JSW ds. strategii i rozwoju:-"Strategia" ma być elementem realnej zmiany w funkcjonowaniu JSW, bo nie da się cały czas robić tego samego i oczekiwać przy tym lepszych rezultatów. Tworzyliśmy ją w sposób nieco zmodyfikowany. Nie mogliśmy się opierać tylko i wyłącznie na planach techniczno-ekonomicznych, bo wiemy z praktyki, że "po drodze" najprawdopodobniej wystąpi szereg zdarzeń, których dzisiaj nie jesteśmy w stanie przewidzieć. To mogą być problemy na rynku, to mogą być problemy z jakością węgla. Wtedy nie będzie już czasu na każdorazową aktualizację "Strategii". W konsekwencji jej założenia szybko przestałyby być użyteczne w procesie zarządzania firmą. "Strategia dla JSW na lata 2018-2030" jest bardzo precyzyjna. Najważniejszym celem strategicznym Grupy Kapitałowej JSW jest umocnienie pozycji wiodącego producenta i dostawcy węgla

ROZMOWA Z ARTUREM DYCZKO P.O. PREZESA ZARZĄDU JSW, ZASTĘPCĄ PREZESA ZARZĄDU DS. TECHNICZNYCH I OPERACYJNYCH.

Styczeń to czas prognoz na 2021 oraz podsumowań ubiegłego roku. Zacznijmy od podsumowania minionego roku:

No cóż, na pewno był to rok niezwykły. Tak dla naszej Spółki, jak i dla wszystkich, którzy walczyli o jej przetrwanie. Nie bójmy się tego powiedzieć, walczyliśmy ramię w ramię o zachowanie miejsc pracy i naszą przyszłość, i w mojej ocenie wyszliśmy obronną ręką z pierwszej fali pandemii, o czym świadczą aktualne wyniki. Dla mnie osobiście był to również rok przełomowy, ponieważ w żaden sposób nie było mnie

The crisis on the coal market combined with the pandemic ruined the mining industry. The Lord speaks of successes:
We closed last year with the extraction of 14.4 million tonnes of net coal, i.e. more than 100,000 tonnes more than in 2010. t more than we planned in September when we updated the technical and economic plan for 2020 after the first wave of the pandemic passed. What pleases the most - nearly 80 percent. of the coal extracted was coal for coking purposes. The most important thing, however, is that in the second quarter of 2020, which was the most difficult for us, when we carried out coronavirus tests among the staff, our mines carried out all commercial contracts unthreatened. The shipment of coal from JSW to Western Europe was in full swing. The same applies to corridor works. In 2020, we completed nearly 73 km of roadway excavations, of which our employees made nearly 62 km, and third-party companies - 11 km. Throughout the year, the intensity of corridor works in the Jastrzębie mines amounted to 5.04, which is a satisfactory level, as it provides our mines with the necessary operational fronts. All that remains is to wait for the price rebound in the coming months.

Budowa nowych kopalń w JSW to konieczność o stanowiącym jeden z filarów strategii rozwoju Jastrzębskiej Spółki Węglowej SA (JSW) projekcie budowy dwóch nowych kopalń, argumentach przemawiających za zakupem Przedsiębiorstwa Budowy Szybów (PBSz) przez JSW oraz planach inwestycyjnych firmy rozmawiamy z zastępcą prezesa zarządu JSW do spraw strategii i rozwoju Arturem Dyczko.
Jako podkreślono w wywiadzie wszystkie działania JSW,  tak jak cała strategia,  są dokładnie przemyślane,  przeliczone i postanowione.
Spółka nie zejdziemy z drogi inwestycji w udostępnienie nowych złóż, gdyż groziłoby to w dłuższej perspektywie utratą fundamentu jej bezpieczeństwa, którym niezmiennie jest i będzie  efektywne wydobycie węgla koksującego oraz produkcja koksu.
The construction of new mines in JSW is a necessity. About the project of building two new mines, which is one of the pillars of the development strategy of Jastrzębska Spółka Węglowa SA (JSW), arguments for the purchase of Przedsiębiorstwo Budowy Szybów (PBSz) by JSW and the company's investment plans, we talk to Artur Dyczko, Deputy President of the JSW Management Board for Strategy and Development.
As emphasized in the interview, all JSW's actions, like the entire strategy, are carefully thought out, calculated and decided.
We will not deviate from investing in the access to new deposits, as this would threaten, in the long term, the loss of the foundation of its security, which is and will always be the effective extraction of coking coal and coke production.
We must know. What is going as planned, what needs to be improved and what we can give up for the time being. In order not to destroy the road leading to the achievement of strategic goals. After experiencing the greatest troubles related... more
We must know. What is going as planned, what needs to be improved and what we can give up for the time being. In order not to destroy the road leading to the achievement of strategic goals. After experiencing the greatest troubles related to the pandemic, it turns out that this knowledge is invaluable, our existence depends on it - says the vice-president of Jastrzębska Spółka Węglowa for technical and operational matters. Acting President of JSW.
The years 2019 and 2020 were difficult for Jastrzębska Spółka Węglowa SA (JSW). Some compared them to the Great Depression of 2015. The downturn, and then the pandemic combined with the downturn, affected the company's income. – We maintained jobs, did not stop key investments, and even in the most difficult times we did not let our contractors down. For the time of the pandemic, in my opinion, we have risen to the occasion. You can always say we didn't do something. However, please remember that in May, June and even July our basic problem was to keep the mines affected by the pandemic. We were dealing with a completely new threat. Factories were being built and JSW mines were working. This is the measure of our success - says Artur Dyczko, head of the JSW Crisis Staff, vice president for technical and operational matters and acting President of JSW S.A.
- Musimy wiedzieć. Co idzie zgodnie z założeniami, co trzeba poprawić i z czego możemy chwilowo zrezygnować. Aby nie zniszczyć drogi prowadzącej do osiągnięcia celów strategicznych. Po doświadczeniach z czasu największych kłopotów związanych z pandemią okazuje się, że ta wiedza jest bezcenna, od niej zależy nasz byt - mówi wiceprezes Jastrzębskiej Spółki Węglowej ds. Technicznych i operacyjnych. Pełniący obowiązki Prezesa JSW.
Lata 2019 i 2020 były dla Jastrzębskiej Spółki Węglowej SA (JSW) ciężkie. Niektórzy porównywali je do czasu wielkiego kryzysu z 2015 roku. Dekoniunktura, a potem pandemia połączona z dekoniunkturą odbiły się na dochodach firmy. – Utrzymaliśmy miejsca pracy, nie wstrzymaliśmy kluczowych inwestycji, nawet w najtrudniejszym czasie nie zawiedliśmy naszych kontrahentów. Jak na czas pandemii to moim zdaniem stanęliśmy na wysokości zadania. Zawsze można powiedzieć, że czegoś nie zrobiliśmy. Jednak proszę pamiętać, że w maju, czerwcu, a nawet w lipcu naszym podstawowym problemem było utrzymanie ruchu w kopalniach, które zostały dotknięte przez pandemię. Mieliśmy do czynienia z zupełnie nowym zagrożeniem. Stawały fabryki, a kopalnie JSW pracowały. To jest miarą naszego sukcesu - mówi Artur Dyczko, szef Sztabu Kryzysowego JSW, wiceprezes ds. technicznych i operacyjnych oraz p.o. prezesa JSW SA.

Jastrzębska Spółka Węglowa - despite the huge difficulties in 2020 caused by the coronavirus and low prices of coking coal - does not lay down its arms. In an extremely difficult period, the crew did not disappoint. She passed the most difficult exam with great success. Motivated by a real threat, focused on defending jobs, her families and loved ones, she did not lose her will to fight. - The JSW crew ended the past year tired but undefeated - says Artur Dyczko, acting as President of JSW SA and Vice-President for technical and operational matters. JSW employees have proven that they can cope with deadly threats and act under pressure. In the first weeks of the year, there was no sign of a pandemic that would change the world. Underground shearers worked at full power, both coking coal production and sales increased. – What came in May, June and July, no one could have expected, because COVID-19 fundamentally changed our plans. We faced a huge number of tasks and problems that our company's plants had never faced before in their history. We only knew that we would not give up and we had to fight for ours - says Artur Dyczko, acting as President of the Management Board of Jastrzębska Spółka Węglowa.
Jastrzębska Spółka Węglowa – mimo ogromnych trudności w 2020 roku spowodowanych coronawirusem i niskimi cenami węgla koksowego – nie składa broni. W wyjątkowo trudnym okresie nie zawiodła załoga. Świetnie zdała najtrudniejszy egzamin. Zmotywowana realnym zagrożeniem, nastawiona na obronę miejsc pracy, swoich rodzin i bliskich nie straciła woli walki. – Miniony rok załoga JSW zakończyła strudzona ale niepokonana – mówi Artur Dyczko, p.o. prezesa JSW SA i wiceprezes do spraw technicznych i operacyjnych. Pracownicy JSW udowodnili, że potrafią sobie radzić ze śmiertelnym zagrożeniem i działać pod presją. W pierwszych tygodniach roku nic jeszcze nie wskazywało na zbliżającą się wielkimi krokami pandemię, która zmieniła świat. Pod ziemią kombajny pracowały z pełną mocą, rosło zarówno wydobycie węgla koksowego, jak i sprzedaż. – Tego, co przyszło w maju, czerwcu i lipcu nikt nie mógł się spodziewać, bo COVID-19 zmienił zasadniczo nasze plany. Stanęliśmy przed olbrzymią liczbą zadań i problemów, z którymi nigdy dotąd w swojej historii zakłady naszej spółki nie miały do czynienia. Wiedzieliśmy tylko, że nie poddamy się i musimy walczyć o swoje – mówi Artur Dyczko, p.o. prezesa zarządu Jastrzębskiej Spółki Węglowej

In 2019, JSW will invest around PLN 2 billion, and by 2030 almost PLN 19 billion. Efficient coal mining, modernization of the coking plant, management of coal derivatives and energy self-sufficiency – these are the most important goals for the entire JSW Capital Group. We strive to achieve them with iron consistency. The main challenges include: improving the efficiency of driving roadway excavations, a modern mining production planning system combined with 3D geological modeling, monitoring the operation of mining machines, autonomous mining complexes and a project to implement an independent rock bolt support at JSW.
Bolter Miner will arrive at the Budryk Mine this summer. In this mine, preparations are underway to start work on the bolt support system. Work is underway to modernize the processing plants in such a way that they prepare not only very good mixtures for coking plants, but also maintain their constant parameters. Not ambitious enough? I am very happy to start work in the area that is the foundation of our change and at the same time the basis of the Industry 4.0 technological revolution, i.e. computerization of the entire production line.

W 2019 roku JSW zainwestuje około 2 mld złotych, a do 2030 roku prawie 19 mld złotych. Efektywne wydobycie węgla, modernizacja koksowni, zagospodarowanie węglopochodnych i samowystarczalność energetyczna – to najważniejsze cele dla całej Grupy Kapitałowej JSW. Z żelazną konsekwencją dążymy do ich osiągnięcia. Główne wyzwania to: poprawa efektywności drążenia wyrobisk korytarzowych, nowoczesny system planowania produkcji górniczej połączony z modelowaniem geologicznym 3D, monitoring pracy maszyn górniczych, autonomiczne kompleksy wydobywcze i projekt wdrożenia samodzielnej obudowy kotwowej w JSW.
Już w wakacje do kopalni Budryk dotrze Bolter Miner. W kopalni tej prowadzone są przygotowania do rozpoczęcia prac w systemie obudowy kotwowej. Trwają prace zmierzające do takiej modernizacji za kładów przeróbczych, aby przygotowywały one nie tylko bardzo dobre mieszanki dla koksowni, ale także utrzymywały ich stałe parametry. Mało ambitnie? Bardzo cieszy mnie rozpoczęcie prac w obszarze będącym fundamentem naszej zmiany i jednocześnie podstawą rewolucji technologicznej Przemysłu 4.0, czyli informatyzacja całego ciągu produkcyjnego.

JASTRZĘBSKA SPÓŁKA WĘGLOWA (JSW) is a world-class power in the industrial use of methane from coal beds and in the construction of modern cogeneration systems. The Department of Methane Drainage and Energy Media Management has been operating within JSW's structures for a year. Methanation departments were established in all mines. Operation and maintenance of methane drainage stations as well as control over the main methane pipeline network were taken over from external companies. These activities serve one purpose - to use methane as a fuel to protect the climate. - Methane is a gas whose greenhouse potential is 28 times greater than that of carbon dioxide. We really need specific financial assistance from EU funds to use climate-damaging gas as a fuel of high ecological value, says Artur Dyczko, Vice-President of JSW SA
for technical and operational matters, in an interview with Nowy Górnik.
Jastrzębska Met Coal is a producer of coking coal, which is on the list of strategic raw materials for the EU. The producer of such an important raw material for the EU economy should not be afraid of anything.
- During the exploitation of coking coal, a large amount of methane is released. We take many actions to reduce its emission to the atmosphere, because we want to protect the climate and use the gas escaping from our mines to generate energy. Our mines have concessions for extracting methane as an accompanying mineral.
The JSW Group mines coking coal, produces coke necessary for steel production and generates energy from methane. This is a reason for glory, not fear for the future - What we do does not always reach the bodies that decide on the directions of the EU climate policy. We must show and promote our activities. So that the policy at both EU and national level does not focus on imposing penalties, but on aid with environmental and energy benefits. The Management Board of JSW sends a clear message: Coal mining is accompanied by methane emissions and we know how to use this harmful gas as blue fuel.
JASTRZĘBSKA SPÓŁKA WĘGLOWA (JSW) jest potęgą na skalę światową w przemysłowym wykorzystaniu metanu z pokładów węgla i w budowie nowoczesnych układów kogeneracyjnych. Od roku w strukturach JSW działa Biuro Odmetanowania i Zarządzania Mediami Energetycznymi. We wszystkich kopalniach powstały oddziały odmetanowania. Przejęto od firm zewnętrznych obsługę i serwis stacji odmetanowania, jak również kontrolę nad siecią głównych rurociągów metanowych. Te działania służą jednemu celowi - wykorzystaniu metanu jako paliwa, aby w ten sposób chronić klimat. - Metan to gaz, którego potencjał cieplarniany jest 28-krotnie większy od dwutlenku węgla. Konkretna pomoc finansowa ze środków unijnych jest nam bardzo potrzebna, aby gaz szkodliwy dla klimatu wykorzystywać jako paliwo o dużych walorach ekologicznych - mówi Artur Dyczko, wiceprezes JSW SA
ds. technicznych i operacyjnych, w rozmowie z Nowym Górnikiem.
Jastrzębska Spotka Węglowa jest producentem węgla koksowego, który jest na liście surowców strategicznych dla UE. Producent tak ważnego surowca dla gospodarki unijnej nie powinien się niczego obawiać.
- Przy eksploatacji węgla koksowego wydziela się duża ilość metanu. Podejmujemy wiele działań, aby zredukować jego emisję do atmosfery, ponieważ chcemy chronić klimat i wykorzystywać gaz ulatniający się z naszych kopalń do wytwarzania energii. Nasze kopalnie mają koncesje na wydobywanie metanu jako kopaliny towarzyszącej.
Grupa JSW wydobywa węgiel koksowy, produkuje koks niezbędny do produkcji stali i wytwarza energię z metanu. To powód do chwały, a nie do obaw o przyszłość - To, co robimy, nie zawsze dociera do gremiów decydujących o kierunkach unijnej polityki klimatycznej. Musimy pokazywać i promować nasze działania. Tak, aby polityka zarówno na poziomie UE, jak i krajowym nie skupiała się na nakładaniu kar, tylko na pomocy dającej korzyści ekologiczne i energetyczne. Zarząd JSW wysyła jasny komunikat: Wydobyciu węgla towarzyszy emisja metanu i my wiemy, jak ten szkodliwy gaz wykorzystywać jako błękitne paliwo.

The IPMA Polska (International Project Management Association) conference was held in Warsaw, during which Jastrzębska Spółka Węglowa received the Polish Project Excellence Award 2018 in the Organizational Projects category. The award was received by JSW Management Board Member Artur Dyczko and the design team. Jastrzębska Spółka Węglowa is consistently transforming the JSW Group into a project organization. Changes are necessary due to the technological revolution taking place in the industry. Innovative techniques, automation of technological processes and diversification of operations within the JSW Group require equally revolutionary changes within the organization. Based on global project management standards, JSW has developed its own program and project management methodology (MZPP), which is tailored to the specifics of the Group and its needs.
The award jury appreciated the project management team at the JSW Group for the project "Implementation of a program and project management system in the Jastrzębska Spółka Węglowa Group". The project was made in accordance with the developed concept, which ensured its place at the forefront of Polish project management.

Dyczko: jesteśmy nowoczesną firmą, na naszych oczach dokonuje się rewolucja w zarządzaniu Jastrzębską Spółką Węglową - Chcemy wyznaczać kierunki rozwoju i być przykładem tego, że przemysł wydobywczy podąża za technologicznymi i organizacyjnymi trendami.

W Warszawie odbyła się konferencja IPMA Polska (International Project Management Association), podczas której Jastrzębska Spółka Węglowa otrzymała nagrodę Polish Project Excellence Award 2018 w kategorii Projekty Organizacyjne. Nagrodę odebrał członek zarządu JSW Artur Dyczko wraz z zespołem projektowym.
Jastrzębska Spółka Węglowa konsekwentnie przekształca Grupę Kapitałową JSW w organizację projektową. Zmiany są niezbędne ze względu na dokonującą się w przemyśle rewolucję technologiczną. Innowacyjne techniki, automatyzacja procesów technologicznych oraz dywersyfikacja działalności w ramach Grupy Kapitałowej JSW wymagają równie rewolucyjnych zmian wewnątrz organizacji. Bazując na rozwiązaniach światowych standardów' zarządzania projektami, JSW wypracowała własną metodykę zarządzania programami i projektami (MZPP), która jest dopasowana do specyfiki Grupy Kapitałowej i jej potrzeb.
Kapituła nagrody doceniła zespół kierowania projektami w Grupie Kapitałowej JSW za projekt „Wdrożenie systemu zarządzania programami i projektami w Grupie Kapitałowej Jastrzębskiej Spółki Węglowej”. Projekt został wykonany zgodnie z opracowaną koncepcją, co zapewniło mu miejsce w czołówce polskiego project managementu.

On May 23, 2019, we received a license to extract hard coal and methane as an accompanying mineral from the Bzie-Dębina 1 Zachód deposit located in the city of Jastrzębie-Zdrój and the communes of Pawłowice and Zebrzydowice in the Pszczyna and Cieszyn counties in the Śląskie Voivodeship. I was relieved because I have been piloting this topic for a long time. Our strategic goal is to extract 2.5 million tonnes of very good quality coking coal annually in the Bzie-Dębina mine in 2030.
This goal cannot be achieved by only exploiting the Bzie-Dębina 2-West field. We have had a concession for part 2-West, in the Jastrzębie-Zdrój commune, for many years. The concession for the remaining south-eastern part of the deposit, located in the Pawłowice, Zebrzydowice and Jastrzębie communes, ended a nearly fifteen-year marathon with formal obstacles. This is great news, because building a mine on half of the deposit would be a bad solution. We would face a basic problem: How to sensibly cut half of the deposit?
At this point, I would like to thank the local government authorities very much. I am glad that we met with the favor of the local community and local government officials.
The construction of the Bzie-Dębina mine is a constant battle against myths. First there was a myth that there is no good coal there. Well, the coal is there, and it's good coal! Then there was the myth that even if there is good coal, it is impossible to reach it. Well, you can reach him. Now, those who wish JSW badly, say: "mining will be expensive." I answer - it will not be cheap, but it will be profitable, because there is coal of good and very good quality in the deposit. I know, because we have just completed the stage of drilling five exploratory wells and we have confirmation of our assumptions from specialists. Specialists also confirmed the tectonics of the orogen. There are probably faults, but in my opinion not such as to make mining unprofitable. The results of the drilling data base did not confirm the existence of some of the fault zones that we expected from the old analysis. The challenge now is to safely overcome the Dębowiec strata. It is, to put it simply, a mixture of water, sand and gas (methane). They separate us from the decks where there are no such threats. Either we will drain these layers, or we will leave the safety shelf and extract coal from unthreatened seams. The decision will be made after detailed research and analysis.
We can act like robbers. Dig up what's best and, after extracting the last ton of coking coal, go where your eyes will take you. Leave the city and region behind. Let it decay. Do we want to behave like gold diggers in the pioneering... more
We can act like robbers. Dig up what's best and, after extracting the last ton of coking coal, go where your eyes will take you. Leave the city and region behind. Let it decay. Do we want to behave like gold diggers in the pioneering times of the United States of America? We can also create foundations for a modern company that will provide decent living for us and the next generations. The Management Board of Jastrzębska Spółka Węglowa is in favor of the second option. That is why we implement the assumptions of CSR (Corporate Social Responsibility).
This means that we are guided by corporate social responsibility for the crew and their families, for the local community, and living conditions in our surroundings. Corporate social responsibility is also a commitment to innovation, without which we will not have a job in a few years.
The Jastrzębie region has been developing for decades thanks to the mines that are part of the Jastrzębie Coal Company. Very good wages, social activities of the mining industry and stable jobs at some point became a barrier to development. High wages deterred investors from other industries because they could not compete with such a generous employer as mining. We can become the curse of the region or start acting as a prudent patron of development.
Możemy zachowywać się jak rabusie. Wykopać to co najlepsze i po wydobyciu ostatniej tony węgla koksowego pójść, dokąd oczy poniosą. Zostawić miasto i region. Niech niszczeje. Czy chcemy zachować się tak jak poszukiwacze złota w pionierskich czasach Stanów Zjednoczonych Ameryki? Możemy także tworzyć fundamenty pod nowoczesną firmę, która będzie dawać godne utrzymanie nam i następnym pokoleniom. Zarząd Jastrzębskiej Spółki Węglowej jest zwolennikiem drugiej możliwości. Dlatego realizujemy założenia CSR (Corporate Social Responsibility).
To oznacza, że kierujemy się społeczną odpowiedzialnością biznesu za załogę i jej rodziny, za społeczność lokalną, warunki życia w naszym otoczeniu. Społeczna odpowiedzialność biznesu to także zobowiązanie do innowacyjności, bez której za kilka lat nie będziemy mieli pracy.
Region jastrzębski od dziesięcioleci rozwija się dzięki kopalniom, które wchodzą w skład jastrzębskiej Spółki Węglowej. Bardzo dobre płace, działalność socjalna górnictwa i stabilne miejsca pracy w pewnym momencie stały się barierą dla rozwoju. Wysokie zarobki odstraszały inwestorów z innych branż, ponieważ nie mogli konkurować z tak hojnym pracodawcą jak górnictwo. Możemy stać się przekleństwem regionu albo zacząć działać jak roztropny mecenas rozwoju.

Representatives of the Australian research agency CSIRO paid a three-day visit to Jastrzębska Spółka Węglowa. The visit of Australians to the Company is the result of an agreement signed two months ago during a government economic mission. The Australian government agency CSIRO (Commonwealth Scientific and Industrial Research Organisation) has existed for over 100 years and is a renowned research and scientific organisation. Using the latest technologies, it creates innovative products and tools to meet the challenges of the mining industry. Among other things, CSIRO has developed detailed systems for modeling the deposit in terms of performance.

Jastrzębska Spółka Węglowa musi być konkurencyjna, dlatego czerpie wiedzę i doświadczenie od najlepszych - Australijczycy są dla nas niezwykle ważnym partnerem. Cieszę się, że współpracujemy z tak prestiżową i liczącą się na świecie instytucją - mówi Artur Dyczko zastępca prezesa zarządu JSW ds. strategii i rozwoju.

W Jastrzębskiej Spółce Węglowej przebywali z trzydniową wizytą przedstawiciele australijskiej agencji badawczej CSIRO. Wizyta Australijczyków w Spółce to efekt porozumienia podpisanego dwa miesiące temu podczas rządowej misji gospodarczej. Australijska agencja rządowa CSIRO (Commonwealth Scientific and Industrial Research Organisation) istnieje od ponad 100 lat i jest renomowaną organizacją badawczo-naukową. Korzystając z najnowszych technologii, tworzy innowacyjne produkty i narzędzia, aby sprostać wyzwaniom związanym z branżą wydobywczą. CSIRO stworzył między innymi szczegółowe systemy modelowania złoża pod kątem wydajności.

JSW modernizes the Group's CENTRAL MEASUREMENT AND RESEARCH LABORATORY. After the modernization, the Jastrzębie laboratory will be the most modern unit of this type in Europe. - This is the heart of the program, which I tentatively called QUALITY FROM DEPOSIT TO SEA - says vice president Artur Dyczko. - The idea is simple - we must at every stage, up to loading on the ship, examine the quality of our production - he emphasizes. Coal production is a technological line that begins in the deposit and ends in the processing plant. What to do to make the product leave the processing plant for which the Company will get the best price? At each stage, quality parameters must be checked. But it's too much. It is necessary to know what lies underground. Therefore, the information coming from the results of geological profiling and deposit modelling is very important. Thanks to this information, a team of analysts will explain the genesis of the disturbances occurring in the deposit. This knowledge, in turn, is necessary to optimally plan and settle mining production. Therefore, it is impossible to implement the Quality program by introducing innovative solutions in only one piece of the technological puzzle. It is best to immediately examine the entire technological line using the latest methods.
Geologists on the first FRONT LINE - Jastrzębska Spółka Węglowa hired 17 geologists, university graduates. "They are very well-prepared specialists who now gain practical knowledge under the supervision of experienced JSW employees. The reception of geologists is like a fragment of a film about the career of young scientists. "We have basically employed an entire scientific club at the Department of Deposit and Mining Geology at the AGH University of Science and Technology modeling parameters describing the quality of hard coal," says Daniel Ozon, President of JSW SA.

Dyczko: Chcąc w JSW być w grupie najlepszych firm wydobywczych na świecie, musimy mieć służby geologiczne na światowym poziomie - proces planowania produkcji trzeba rozpocząć od bezbłędnego rozpoznania złoża, stąd nasze motto: JAKOŚĆ OD ZŁOŻA DO MORZA

Po modernizacji jastrzębskie laboratorium będzie najnowocześniejszą tego typu jednostką w Europie. - To serce programu, który roboczo nazwałem JAKOŚĆ OD ZŁOŻA DO MORZA - mówi wiceprezes Artur Dyczko. - Idea jest prosta - musimy na każdym etapie, aż do załadunku na statek, badać jakość naszej produkcji - podkreśla. Produkcja węgla to ciąg technologiczny, który zaczyna się w złożu, a kończy się w zakładzie przeróbczym. Co zrobić, żeby z zakładu przeróbczego wyjechał produkt, za który Spółka dostanie najlepszą cenę? Na każdym etapie trzeba prowadzić kontrolę parametrów jakościowych. Ale to za mato. Trzeba wiedzieć, co leży pod ziemią. Dlatego bardzo ważne są informacje płynące z wyników profilowań geologicznych i modelowania złoża. Dzięki tym informacjom zespól analityków wyjaśni genezę występujących w złożu zaburzeń. Ta wiedza z kolei jest niezbędna, aby optymalnie zaplanować i rozliczyć produkcję górniczą. Dlatego nie da się zrealizować programu Jakość, wprowadzając innowacyjne rozwiązania tylko w jednym elemencie technologicznej układanki. Najlepiej od razu badać cały ciąg technologiczny za pomocą najnowszych metod.
Geolodzy na pierwszej LINII FRONTU - Jastrzębska Spółka Węglowa przyjęła do pracy 17 geologów, absolwentów wyższej uczelni. - To bardzo dobrze przygotowani specjaliści, którzy teraz zdobywają wiedzę praktyczną pod okiem doświadczonych pracowników JSW. Przyjęcie geologów to niczym fragment filmu o karierze młodych naukowców. - Zatrudniliśmy w zasadzie cale koło naukowe zajmujące się w Katedrze Geologii Złożowej i Górniczej AGH modelowaniem parametrów opisujących jakość węgla kamiennego - - mówi Daniel Ozon, prezes JSW SA.

Prace na strategią zrównoważonego rozwoju prowadzone były  w oparciu o podeście prezentowane w normie PN-ISO 26000. W pierwszym kroku, podczas warsztatu wewnętrznego, w którym wzięli  udział kierownicy i koordynatorzy  reprezentujący różne obszary  i funkcje biznesowe, związane  ze zrównoważonym rozwojem  i odpowiedzialnym zarządzaniem,  zdefiniowali:
• kluczowe obszary odpowiedzialności,
• kluczowe grupy interesariuszy.
W kolejnym kroku z osobami  odpowiedzialnymi za poszczególne obszary przeprowadzone zostały  pogłębione wywiady. W efekcie wypracowano konkretne już mierniki dla zdefiniowanych wcześniej  celów oraz przyjęto ich wartości na  najbliższe lata.
