Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of the study is the safety of mining operations at the mining sites of the coal mines. The purpose of the work is to agree on a 1-M type feedback, ventilation scheme 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 18 southern lava of the reservoir l1 of slope № 1 of LLC "Mine 1-3 Novogrodivskа", to agree the acts of establishing technically achievable residual air dust levels for 2020 and to conclude on the feasibility of using pre-wet coal in the array. 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 site of 18 southern lava of the coal seam l1 of the slope № 1 of LLC "Mine 1-3 Novogrodivskа" were analyzed. Developed "Recommendations for ensuring gas safety of the excavation section 18 of the southern lava of the reservoir l1 of the slope № 1 when applying a 1-M back-flow ventilation scheme", the calculation of the air flow rate required for its ventilation and the maximum permissible load on the clearing hole by the gas factor, subject to the implementation of the developed recommendations for ensuring gas safety. The act of establishing technically achievable levels of residual dust content in the LLC "Mine 1-3 Novogrodivskа" was agreed. Developed "The conclusion of inappropriate use of coal seam prior wetting l1 at the site of extraction works in 18 southern slope bench № 1 of LLC "Mine 1-3 Novogrodivskа". As a result of the implementation of the developed recommendations, the safety of mining operations is ensured, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2020-07-03 Close
