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.
