Purpose - adjustment of the process parameters of the hydrodynamic effects through one borehole on underground coal seams prone to gas dynamic phenomenon before opening them in the mine name is F.E. Dzerzhinsky. Subject of research - the process parameters of the hydrodynamic effects on a busy gas-saturated coal seam prior to its opening. Research methods - analytical, experimental studies for mines. Industry conducted verification method of hydrodynamic impact on the coal seams m3-"Tolstyj - Vostok", m3-"Tolstyj - Zapad", m2-"Tonkij - Zapad" and m2-"Tonkij - Zapad" prone to gas-dynamic phenomena, before opening through one process borehole under SE "Mine name is FE Dzerzhinsky "SE" Dzerzhinskugol." Found that the hydrodynamic impact via one well of 100 mm diameter, drilled through the soil seams breed cork capacity of more than 5 m from the bottom of the normal revealing the excavation section in sinking to 12.3 m2 on the coal seam at the top or at the power cork breed less than 5.0 m, in an amount of 15-30 cycles and of extracting from the processing zone for at least 2% of the coal in the coal seam results in a state on a ground outburst 6,8-10,2 m radius. As a result, industrial test method adjusted parameters of hydrodynamic impuct on coal seam prior to its opening: Number of technological borehole piece .1; The impact of process pressure, 4-5 MPa; The number of cycles, 15-30 cycle; Cycle time, 3-10 min. Opening of coalbed m3-"Tolstuj" m2-"Tonkij" № 42-1146 m sections and № 41-1146 m crosscuts intermediate number 8, № 9, № 17 and № 18 conducted without signs of the gas-dynamic phenomena. Hydrodynamic impact, of technological boreholes, average daily concentrations.
