Abstract: Future development of mining operations along with creation of new mines, will be supported by modernization and reconstruction of existing enterprises. Creation of mechanized coal face systems that ensure complete extraction of coal reserves with the supply of occupational safety is prospective. One of the most effective technologies for the development of high coals is their mining from wall to wall with drawing coal from the roof layer into the under-cutting layer. Research of a new design of mechanized support was carried out using the developed simulation model based on the discrete elements method in the Rocky DEM environment. The amount of coal losses remaining in the mined-out space is determined. The opportunity of using the developed model is demonstrated for analyzing the flows of the coal-bearing mass in the implementation of the technology of coal mining from high flat-lying coal seams to identify new patterns and ways to improve the efficiency of the technology before its implementation in coal mines.
Keywords: simulation modeling, technology of mining high coal beds, under-roof coal output, mechanized powered roof support, trajectory of particle motion, the method of discrete elements, model parameters
