Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of the research is the safety of mining operations on gas-dynamic phenomena in the conditions of DTEK Dobropolyeugol LLC. The purpose of the work is to develop technical solutions for the safe mining of coal seams prone to gas-dynamic phenomena in the mining and geological conditions of the Dobropolskaya and Almaznaya mines of DTEK Dobropolyeugol. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the technical documentation for mining the excavation sites and the mine workings of DTEK Dobropolyeugol LLC was analyzed. The calculation of the boundaries of the protective action of the overworking of the l3 reservoir in the area of ​​the human and cargo walkings of the l2 reservoir and the bypass crosshead of the 5 horizon of the southern slope of the Dobropolskaya mine was carried out. A "Complex of measures to combat gas-dynamic phenomena during preparatory workings on the l21 stratum of the Dobropolskaya mine for 2018" has been developed. Developed measures to prevent gas-dynamic phenomena and ensure the safety of working during the mine workings and mining of coal seams, Passport opening of coal seams of the Dobropolskaya and Almaznaya mines. Recommendations for the safe conduct of mine workings on outburst sandstones and coal seams prone to gas-dynamic phenomena, and Recommendations for the safe mining of coal strata prone to gas-dynamic phenomena, Dobropolskaya and Almaznaya mines were developed. As a result of the application of the developed recommendations, the safety of mining operations is ensured, which is of great socio-economic and environmental importance.
