Information × Registration Number 0220U101799, 0119U102635 , R & D reports Title Agree on a star-flow type 1-M ventilation pattern and calculation of air flow required for ventilation of the clearing generation and the excavation section, as well as the load allowed by the gas factor on the clearing face of the 9 southern lava of Block 10 of Private Joint-stock Company «РokrovskoeMineGroup» in 2019 year popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 24-02-2020 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 1-M ventilation scheme and the calculation of the air flow required for ventilation of the treatment plant and the excavation site, as well as the load permissible by the gas factor on the treatment hole of the 9th south lava of block 10 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 9th south lava of block 10 of d4 layer of PJSC «Management of the mine «POKROVSKE» were analyzed. Developed "Recommendations for ensuring gas safety of the recessing section of the 9th south lava block 10 of d4 layer of PJSC «Management of the mine «POKROVSKE» when applying a precision ventilation scheme, type 1-M". Approval of a reciprocating, type 1-M, ventilation scheme of the excavation section 9 of the southern lava of block 10, the calculation of the flow rate of air required for its ventilation, and the maximum allowable load on the clearing hole by the gas factor at the first and second stages of the lava exploration, subject to the implementation of developed recommendations to ensure gas safety. 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.
