The purpose of the work is to adjust the parameters of the GDA method through one underground well to coal seams prone to GDA, before their opening in the conditions of the SE "Central Mine" SS "Toretskvugillya". Research methods are analytical, mine experimental research. An industrial test of the method of HDA for coal seams was carried out m2-"Thin" and m3-"Thick", which are prone to GD, before their opening through one technological well in the conditions of the SE "Central Mine" SS "Toretskvugilya". It was established that during the execution of the drilling operation through one well with a diameter of 100 mm, drilled through a rock plug of the soil or a roof with a capacity of more than 5 m from the normal with a cut-out cutting with a cross-section in the penetration of up to 12.3 m2 per coal seam, in the amount of 12-45 cycles and extraction from the processing zone, at least 2% of coal brings the coal seam into an emission-safe state in an area with a radius of more than 7 m. The dissection of coal seams m3-"Thick" with intermediate crosscuts No. 30 and m2-"Thin" with deep crosscuts No. 31 in section No. 41-1146 m was performed without signs of gas-dynamic phenomena. The conducted research allows to adjust the parameters of the coal seam gas station, which will reduce the costs of processing the seam, improve the working conditions and safety of the miners.
