Purpose - the adjustment parameters of the process of hydrodynamic impact through a underground borehole in coal seams prone to GDP, before opening them in a OE "Mine the FE Dzerzhinsky "SE" Dzerzhinskugol ". Subject of research - the process parameters of the hydrodynamic impact on the strained gas-saturated coal seam before its opening. Research methods - analytical, experimental studies of mine. Spend industrial testing method of hydrodynamic impact on coal seams m2- "Tonkiy" and m3- "Tolstuj", prone to gas-dynamic phenomena, before their opening through a process well under OE "Mine the. FE Dzerzhinsky "SE" Dzerzhinskugol ". It was found that the hydrodynamic impact through one borehole of 100 mm diameter, drilled through soil breed cork seams 5 m along the normal from the bottom reveals the development of cross-section in the sinking to 12.3 m2 for coal seam at the top or at the power plug rock less than 5.0 m, in an amount of 12-46 cycles of the extraction and treatment zone of not less than 2% of the coal in the coal seam results no outburst condition 6,4-10,2 m radius portion. As a result of industrial tests way to adjust the parameters of HDI on the coal seam before its opening:- The number of technological wells, pieces ................................ ....1; - The impact of process pressure, MPa ..........................................4-6; - The number of cycles, cycle ............................... ........................ 12-46. Opening coalbed m3- " Tolstuj " and m2- " Tonkiy " area №41-1146 m intermediate crosscuts №19 and №20, as borehole as the formation m2- " Tonkiy " №42-1146 m area №10 on the panel made no signs of symptoms gas-dynamic phenomena. Hydrodynamic impact, technological borehole, crosscut, daily average concentrations.
