The paper deals with simulation of in-situ uranium leaching technological process, collecting data for forecasting and leaching process control. It provides numerical simulation of uranium in-situ leaching (ISL) using Comsol Multiphysics software package application. Previous studies evaluated main hydrodynamic characteristics of wells and reservoirs, such as the coefficient of resistance and the saturation recovery; while this paper is concerned with determining the changes in process variables in the wells during operation.

Constant and efficient operation of technological processes without incidents is of a paramount importance for any enterprise. Nevertheless, if any incident happens, the operation staff should be properly trained in order to avoid serious consequences and such training should be as close to the reality as possible. Virtual training application (VTA) that we introduce by this paper can perfectly meet this target and can be widely used for effective staff training by modern companies and enterprises. This paper proposes VTA plans and specifications considering technical requirements and rules applied for production processes and training simulators. It elaborately presents how the simulation technology can be used based on the example of uranium in-situ leaching process analysis. Introduced VTA plans and specifications can help the training operator staff learn and simulate the mentioned above process and this knowledge can be obtained without interruption of the working process of an enterprise. Virtual simulator is based on a simulation model of the technological equipment, and the difficulty level of training and further development of the dynamics of the training developed with the help of artificial intelligence. Streszczenie. Ciągły i efektywny przebieg procesów technologicznych, bez występowania sytuacji nietypowych ma kluczowe znaczenie w działaniu każdego przedsiębiorstwa. Niemniej jednak, w takich przypadkach obsługa powinna być właściwie przeszkolona, co powinno zostać przeprowadzone w warunkach możliwie jak najbardziej zbliżonych do rzeczywistych. Niniejszy artykuł prezentuję aplikację wirtualnego trenażera (VTA – virtual training application), który może zostać szeroko wykorzystany w praktycznym szkoleniu personelu. W artykule zaprezentowano ponadto obejmowane przez VTA scenariusze działania, które biorą pod uwagę reguły i wymagania techniczne związane z danym procesem wytwórczym. Działanie VTA zostało pokazane na przykładzie technologii procesu ługowania uranu in situ. Zaimplementowane plany i specyfikacje pozwalają szkolonemu personelowi zrozumieć specyfikę wspomnianego procesu, co odbywa się bez jakiejkolwiek ingerencji w działanie przedsiębiorstwa. W trenażerze wykorzystano modele symulacyjne rzeczywistych urządzeń, a funkcjonowanie całości, dla różnych poziomów trudności trenażera, zostało zamodelowane dzięki zastosowaniu metod sztucznej inteligencji.

The article is devoted to numerical modeling of uranium in-situ leaching process, which enables to assess the dynamics of the technological process. Efficient simulation of in-situuin-situ leaching is an urgent task, demanded by many enterprises of the mining industry worldwide. Mathematical modeling, given in the article, describes the dynamics of in-situ leaching. It should be borne in mind that in-situ leaching has characteristics, in connection with which its use becomes specific, it requires some knowledge and tools for analysis and management process. Designed to be a conceptual model allows to take into account all the information about the geological environment, the geometrical properties of hydraulic parameters of solid state properties, including homogeneous and isotropic, fluid properties, boundary conditions.
