Poljakov of National Academy of Sciences of Ukraine popup.description2   As a result of the work, the technical documentation on the mine workings and the clean-up work under the conditions of Public Joint-stock Company "ÐokrovskoeMineGroup" was analyzed. With the use of numerical modeling, the study of the occurrence of coupled geo-and gas-dynamic processes during the formation of discharge gaps as a way to prevent gas-dynamic phenomena in the mine working face was carried out. Developed Recommendations for the safe conduct of mine workings and the safe conduct of cleaning work. Developed measures to prevent sudden emissions of coal, rock and gas in the preparatory and clearing faces with the use of hydraulic erosion of the coal seam, the formation of the discharge cavity and the execution of drilling and blasting operations in the shaking blast. Works on the establishment of zones not hazardous by gas-dynamic phenomena were developed, a Conclusion was developed on the outburst hazard degree of the coal seam d4, prone to gas-dynamic phenomena, in block No. 10. Participation in the Commission on the definition of the category of outburst hazard and the procedure for mining of mined plastics prone to gas-dynamic phenomena at Public Joint-stock Company "ÐokrovskoeMineGroup". The results of the implementation of the development - safety is ensured during mine workings and the conduct of cleaning work on outburst coal seams in the conditions of Public Joint-stock Company "ÐokrovskoeMineGroup", which is of great socio-economic and environmental importance.
