Head Minieiev Serhii P., Доктор технічних наук Registration Date 13-12-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description1 To agree on a reverse-precision, type 1-M, ventilation scheme and calculation of the air consumption required for ventilation of the treatment workings and the excavation area, as well as the permissible gas factor load on the treatment outcrop 11 of the northern bench of block 10 of PJSC «Management of the mine «POKROVSKE» in 2024. 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 gas safety of the excavation site 11 of the northern bench of block 10 PJSC «Management of the mine «POKROVSKE» when using a reverse flow ventilation scheme, type 1-M. 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, schemes and parameters of ventilation of the workings of the mining area 11 of the northern bench of block 10 of PJSC «Management of the mine «POKROVSKE» were analyzed. "Recommendations for ensuring gas safety of excavation site 11 of the northern bench of block 10 of layer d4 when using a reverse flow ventilation scheme of type 1-M" were developed. The application of the reverse flow type 1-M, the ventilation scheme of the excavation area 11 of the northern bench of block 10 of the d4 layer, the calculation of the air flow required for its ventilation, and the maximum permissible load on the cleaning outcrop according to the gas factor were agreed upon, subject to the implementation of the developed recommendations for ensuring gas safety. As a result of the application of the developed recommendations, the safety of mining operations will be increased, which is of great socio-economic and ecological importance.
