The purpose of the work is to develop a set of technical solutions for the safe development of coal seams prone to gas-dynamic phenomena in the mining and geological conditions of the mine «Dobropilska» PSD "MINE MANAGEMENT DOBROPILSKE" LLC "DFEK Dobropillyavugilyal". Research methods - generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the system of air and gas control during the operation of excavation sites and dead-end workings of the mine "Dobropilska" was analyzed. After correcting the remarks, the project of the system of automatic centralized telecontrol of methane content in the workings of the mine «Dobropilska» was approved. Developed "Recommendations for safe operation of coal seam l21, prone to gas-dynamic phenomena, 2 southern lava southern slope of the horizon 450 m, without illumination of the output air stream", "Recommendations for prevention of sudden emissions of sandstone and gas during ventilation lath51 horizon 450 m "," Recommendations for dust and gas and fire safety in the operation of the main transport workings, equipped with conveyor belts of the mine "Dobropilska". As a result of the application 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 2021-03-25 Close
