Abstract. The results of theoretical and experimental methods of calculation of dynamic parameters of hydroimpulsive influence on outburst coal layer are resulted in the article. Based on the studies was substantiated the dynamic parameters and operating ranges of pulsed liquid injection modes, enhanced mathematical model of an engineering method for calculating the frequency and amplitude of self-oscillation cavitations. It is set that conformity to the law of change of maximums of scope of self-oscillation from back water pressure of liquid in a mining hole, characterizes the change of coal layer hydro resistance in the process of him hydro breaking and is described by parabolic dependence of the second degree. It was determined that parameters of the dynamic loading of coal layers in the impulsive injection mode of hydro breaking in outburst layers conditions are satisfy
Keywords: Keywords: hydroimpulsive influence, coal layer, injection mode, frequency and scope of selfoscillation, working range
