Registration Date 30-05-2022 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of research - the safety of mining operations in the excavation areas of coal mines. The purpose of the work is to develop recommendations to ensure safe development of coal seam d4, dangerous for sudden emissions of coal and gas, 1 southern lava of unit 1 of PJSC «Management of the mine "POKROVSKE". Research methods - generalization and analysis of results, methods mat. statistics, calculations according to standard methods. As a result of the work, the mining-geological and mining-technical characteristics of the excavation section 1 of the southern lava of block 1 of PJSC «Management of the mine "POKROVSKE" were analyzed. "Recommendations for ensuring safe development of coal seam d4, dangerous for sudden emissions of coal and gas, 1 southern lava of Unit 1 of PJSC «Management of the mine "POKROVSKE" when supplying fresh air to one or more workings without illumination of the output ventilation air jet. It has been agreed to test 1 the southern lava of Unit 1 with the supply of fresh air to the clean-up face of one workout without illuminating the outlet air flow, provided that the developed recommendations for gas safety are met. 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.  Product Description popup.authors popup.nrat_date 2022-05-30 Close
