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 PJSC "Management of the mine Pokrovske". Research methods - generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, he took part in the commission to determine the category of emission hazard and the procedure for testing mines prone to gas-dynamic phenomena at PJSC "Management of the mine Pokrovske". A set of measures has been developed to combat gas-dynamic phenomena during preparatory workings and cleaning works. Developed "Recommendations for the prevention of sudden emissions of coal, rock and gas during the 8 northern conveyor lane block №10 and installation walker 8 northern" devil "lava block №10", "Recommendations for safe opening of coal seam d4, prone to gas-dynamic phenomena 8, conveyor drift of unit №10", "Recommendations for safe opening of coal seam d4, prone to gas-dynamic phenomena, 9 northern "bis" conveyor drift of unit №10". Zones safe for coal and gas emissions or extrusion have been installed on the formations. Checking and calibration of ПГ-2MA devices on the stand of СИПГ type and check of springs of strength meter П-1 on installation of УІЖ type are executed. Forecasts of coal seam emission hazard at the opening site have been fulfilled. 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 2021-06-22 Close
