Information × Registration Number 0220U100362, 0119U103317 , R & D reports Title To agree on a precision, type 1-M, scheme of ventilation and calculation of air flow, necessary for ventilation of the treatment plant and excavation site, as well as the permissible gas load on the clearing of the entire lava of Unit 5 of Private Joint-Stock Company «POKROVSKE» Mine Management», 2019. popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 16-01-2020 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 the coal mines. The purpose of the work is to agree on a precision, type 1-M, ventilation scheme and calculation of the air flow required for ventilation of the treatment plant and the excavation site, as well as, permissible by the gas factor of the load for the clearing of the whole lava of the block 5 of PJSC «POKROVSKE» Mine Management». Research methods – generalization and analysis of results, methods of mat. statistics, calculations by standard methods. As a result of the work, the mining-geological and mining characteristics of the excavation section of the entire lava block of block 5 of d4 PJSC «POKROVSKE» Mine Management» were analyzed. Developed "Recommendations for ensuring gas safety of the recessing section of the entire lava block 5 of d4 layer of PJSC «POKROVSKE» Mine Management» when applying a 1-M feedback ventilation scheme. Agreed the use of a 1-M reciprocating ventilation section of the excavating unit , the calculation of the air flow required to ventilate it, and the maximum permissible load on the gas-discharge clearing, subject to the implementation of the developed recommendations. 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.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
