The purpose of the work is to correct the parameters of the GDV method through a single underground well to coal seams that are prone to GDYA, before opening them in the conditions of the OP "Tsentralnaya Mine" of the "Toretskugol" SE. The subject of the study - the parameters of the method GDV on a stressed gas-saturated coal seam before it is opened. Research methods - analytical, mining experimental research. An industrial test of the gas-dynamic effect on the m2- "Thin" and m3- "Thick" coal seams, prone to gas-dynamic phenomena, was performed before they were opened through one process well under the conditions of the "Tsentralnaya" mine "GP" Toretskugol ". It was established that when performing a gas-dynamic effect through a single well with a diameter of 100 mm, drilled through the rock plug of the soil or roof with a capacity of more than 5 m along the normal of the bottomhole revealing output with a cross section in the penetration of up to 12.3 m2 to a coal seam, and in the amount of 14-38 from a treatment zone of at least 2% of coal, leads the coal seam to a non-hazardous state on a site with a radius of 8.9-16.9 m. The opening of coal seams m3- "Thick" with intermediate cross-sections No. 24 and No. 25 and m2- "Thin" with industrial number 25 and No. 26 at section 41-1146 m, as well as industrial cover No. 12 at section No. 42-1146 m without signs manifestations of gas-dynamic phenomena. Performed studies allow to adjust the parameters of GDV on coal seam, which will reduce the cost of performing formation treatment, improve the conditions and safety of miners.
