Registration Date 08-01-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the study is the safety of mining operations in the mining areas of coal mines. The purpose of the work is to develop recommendations for ensuring the safe exploitation of the d4 coal seam, which is threatened by sudden coal and gas emissions, 9 of the northern bench of unit 10 of PJSC «Management of the mine «POKROVSKE» by supplying fresh air to the cleaning face one at a time without refreshing the outlet ventilation air stream. Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the mining-geological and mining-technical characteristics of the quarry section 9 of the northern bench of block 10 of PJSC «Management of the mine «POKROVSKE» were analyzed. "Recommendations for ensuring the safe exploitation of coal seam d4, threatened by sudden releases of coal and gas, 9 of the northern bench of unit 10 of PJSC «Management of the mine «POKROVSKE» for supplying fresh air to the cleaning face of one production without refreshing the exit ventilation jet of air" have been developed. It has been agreed to work out 9 of the northern bench of block 10 with the supply of fresh air to the cleaning face of one production without refreshing the outgoing air stream, provided that the developed recommendations for ensuring 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 ecological importance.  Product Description popup.authors popup.nrat_date 2024-01-08 Close
