 The object of research is to ensure the safety of mining operations in the conditions of the mine "Almazna" PSD «Mine Management "Dobropilske" LLC "DFEK Dobropillyavugillya". 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 «Almazna» mine. 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 hazards and the procedure for testing mines prone to gas-dynamic phenomena at the mines of the PSD «Mine Management "Dobropilske" LLC "DFEK Dobropillyavugillya" for 2021. A set of measures to combat gas-dynamic phenomena in the conduct of mining operations at the «Almazna» mine for 2021 has been developed. Developed "Recommendations for safe mining - ventilation lane 3 northern lava formation l1", "Recommendations for safe operation of coal seam l1, prone to gas-dynamic phenomena, 3 southern lava РPU, without illumination of the output ventilation air flow", "Recommendations for safe conveyor lane 3 of the northern lava of the l1 formation of the РPU on the coal seam, prone to gas-dynamic phenomena". Zones that are safe for coal and gas emissions or extrusion have been established (exploration or control observations from the current emission hazard forecast). Checking and calibration of PG-2MA devices on the stand of the СИПГ type and check of the springs of the P-1 strength meter on the УІЖ type installation were performed. Calculations of protected zones and zones of high mountain pressure were performed. 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.
