Information × Registration Number 0221U105100, 0120U105203 , R & D reports Title Carry out a study of methane sources and agree on the operation of the 3 southern lava of unit 7 without illumination of the output air stream and the operation of the combine according to the shuttle scheme, in 2020. popup.stage_title Head Minieiev Serhii Р., Registration Date 04-06-2021 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of research is the safety of mining operations at excavation sites of coal mines. The purpose of the work is to develop recommendations for safe development of coal seam d4, threatened by sudden emissions of coal and gas, 3 southern lava of unit 7 of PJSC «Mine Management «Pokrovske» when supplying fresh air to the treatment face one production without illumination of the output ventilation air stream. Research methods – generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the mining-geological and mining-technical characteristics of the excavation section 2 of the southern lava of the block 7 of the d4 formation of PJSC «Mine Management «Pokrovske» were analyzed. "Recommendations for ensuring safe development of coal seam d4, threatened by sudden emissions of coal and gas, 3 southern lava of block 7 of PJSC «Mine Management «Pokrovske» when supplying fresh air to the treatment face one by one without illuminating the outlet ventilation air stream. 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 2021-06-04 Close
