Information × Registration Number 0222U003775, 0121U113240 , R & D reports Title Agree on a reverse, type 1-M, ventilation scheme and calculation of air flow required for ventilation of the treatment plant and excavation site, as well as the allowable gas load on the treatment face 4 of the southern lava of block 7 of PJSC «Management of the mine "POKROVSKE", in 2021. popup.stage_title Head Minieiev Serhii Р., д.т.н. 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 is the safety of mining operations in the excavation sections of coal mines. The purpose of the work is to develop recommendations for ensuring gas safety of the excavation section 4 of the southern lava of Unit 7 of PJSC «Management of the mine "POKROVSKE" when using a reverse ventilation scheme, type 1-M. 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 4 of the southern lava of block 7 of PJSC «Management of the mine "POKROVSKE" were analyzed. "Recommendations for ensuring gas safety of the excavation section 4 of the southern lava of Unit 7 of PJSC «Management of the mine "POKROVSKE" using a reverse ventilation scheme, type 1-M" were developed. The application of a reverse-precision, type 1-M, ventilation scheme of the excavation section 4 of the southern lava of Unit 7, calculation of the air flow required for its ventilation, and the maximum allowable load on the clean-up face by gas factor are agreed. 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
