The article presents the results of hydrodynamic impact (HDI) on outburst-hazardous coal seams during work to prevent sudden outbursts of coal and gas in the mines of the Central District of Donbass. We are considering these results as scientific and industrial studies of the parameters of influence on the "coal-gas" system. Studies of the criteria for control and evaluating the effectiveness of HDI. Their analysis from the standpoint of initiating self-destruction and active degassing of a coal-rock array are given. The effect of self-destruction of the "coal-gas" system is considered as the result of the destruction process of the supramolecular assembly of the coal matter macromolecule, the detachment of the carbon molecule with formation of methane molecules. The influence of geomechanical factors on the efficiency of HDI has been established and studied in a practical way when provoking and maintaining the process of self-destruction of the "coal-gas" system through the borehole.
