Purpose - to develop schemes of laying of technological holes and testholes, as well as setting the parameters of the hydrodynamic impact providing contiguous unloading coal seams k3l-"Derezovka" k3u, "Derezovka-upper" and k3l, "Derezovka-bottom" hydrodynamic impact before opening slaughter crosscut ІVPSH-133 in the level 1,146 m Subdivision "Mine named. Dzerzhinsky. The subject of research - the parameters of the method of hydrodynamic impact on stressful gas-saturated coal seam prior to its opening. Research methods - analytical, experimental studies of mine. On the basis of experimental investigations of the mine of the hydrodynamic impact on coal seams k3-"Derezovka" k3u, "Derezovka-upper" andk3n, "Derezovka-bottom" level 1146 m from the equipment through hole determineddynamics of the daily average concentration of methane in the gas mixture, the coefficients of the intensification of degassing and degassing treated solid. By quantity coal extracted from the hole defined radius of disintegrated coal around the borehole and set the parameters of the hydrodynamic impact on coal seams before opening: - the number of technology holes, units ..... 1 - process pressure effects, MPa ...... 5-6 - quantity extracted coal from a zone...... 2% - coefficient of degassing treated zone .... ...> 0.45. Autopsies coalbed k3-"Derezovka" k3u, "Derezovka-upper" and k3l, "Derezovka-bottom" crosscut ІVPSH-133 carried out without signs of the gas-dynamic phenomena.
