Information × Registration Number 0219U101162, 0118U007658 , R & D reports Title Conduct a study of methane emissions sources and coordinate the work of the 14 south lava block 10 without refluxing the outflow of air and the work of the harvester according to the bidirectional scheme, in 2018 popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 13-05-2019 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 gas safety of excavated areas of coal mines. The purpose of the work is to review the submitted documents and agree on the development of 14 southern lava unit 10 of Public Joint-stock Company "РokrovskoeMineGroup" without refreshing the outgoing air stream. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the mining characteristics of the excavation section 14 of the southern lava of block 10 of Public Joint-stock Company "РokrovskoeMineGroup" were analyzed. The analysis of gas safety in the workings of the excavation site at the planned loads on the working face and the means of degassing and ventilation. Developed "Recommendations for the safe mining of coal seam d4, prone to gas-dynamic phenomena, 14 southern lava unit 10 of Public Joint-stock Company "РokrovskoeMineGroup" without refreshment of the outgoing air ventilation stream. " It was agreed to work out 14 southern lava units of block 10 without refreshing the outgoing air stream, subject to the implementation of the developed recommendations for ensuring gas safety. The results of the implementation of the development - the application of the developed recommendations helped to ensure gas safety in mining, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
