It has been substantiated the technological parameters of the method of vibratory processing of coal-face of steep outburst-prone layer of lava sheet. The character of the change in the stress-strain state of coal massif before and after the influence of wave has been found out. The efficiency of influence has been estimated by the complex method that includes initial speed of gas, resistance of a seam to cutting and electrometric sounding of a massif.
