Information × Registration Number 0220U102533, 0119U101660 , R & D reports Title To approve the return-type, type 1-M, the air flow diagram and the calculation of the air flow required for ventilation of the treatment work and the drainage area, as well as the allowable by gas factor load on the purification of the hollow lava block 3 Private Joint-stock Company "РokrovskoeMineGroup", in 2019 popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 17-03-2020 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of the study is the ventilation of the mining sites of coal mines. The purpose of the work is to agree on a precision, type 1-M, scheme of ventilation and calculation of the air flow required for ventilation of the treatment plant and the excavation site, as well as the permissible gas load of the entire lava block 3 of PJSC «Management of the mine «POKROVSKE». Research methods – generalization and analysis of results, methods of mat. statistics, calculations by standard methods. As a result of the work, the mining technical characteristics of the excavation section of the entire lava block of block 3 of d4 of PJSC «Management of the mine «POKROVSKE» were analyzed. Developed "Recommendations for ensuring gas safety of the excavation section of the whole lava block of block 3 of d4 of PJSC «Management of the mine «POKROVSKE» when applying a back-flow ventilation scheme, type 1-M". The use of a 1-M reverse-precision scheme of ventilation of the excavation section of the entire lava unit of block 3 was agreed, the air flow required for its ventilation was calculated and the maximum permissible loading on the gas-discharge face at the first and second stages of working out. Results of the implementation of the development – application of the developed recommendations made it possible to ensure gas safety during mining operations, which is of great socio-economic and environmental importance.
