Information × Registration Number 0223U002452, 0122U201244 , R & D reports Title To conduct a study of the sources of methane emission and agree on the operation of the 9 southern "bis" lava of unit 10 without refreshing the output air jet and the operation of the combine according to the shuttle scheme, in 2022 popup.stage_title Head Minieiev Serhii Р., д.т.н. Registration Date 21-02-2023 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 development of coal seam d4, which is threatened by sudden coal and gas emissions, 9 southern "bis" lava of unit 10 of PJSC «Management of the mine «POKROVSKE» for supplying fresh air to the cleaning face of one production without refreshing the outlet ventilation jet air. 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 southern "bis" lava 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 southern "bis" lava of unit 10 of PJSC «Management of the mine «POKROVSKE» for supplying fresh air to the cleaning face of one production without refreshing the outlet ventilation air stream". It was agreed to work out 9 of the southern "bis" bench of block 10 with the supply of fresh air to the cleaning face one piece at a time without refreshing the outgoing air jet, 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 2023-02-21 Close
