Abstract. Described the physical nature of the hydrodynamic method impact on stressful mas-sif of gas-saturated coal through underground wells. Method assumes the violation of steady state in the "well-coal mass" through the implementation of the cyclic alternating loadings changes com-bined with natural factors: pressure of surrounding rocks, structure seam and fraction of gas of the coal. On the basis of the method is provided a process the degassing and reducing gas-dynamic ac-tivity of the upper part of the coal strip to work off shield unit. On the basis of the method is pro-vided a process reducing the degassing and gas-dynamic activity of the upper part of the coal strip to work off shield unit. For different mining and geological and mining conditions of working off of gassy steep coal seams. Developed by technological schemes of bringing coal seams in the top of the lava in the application of state emissions safe hydrodynamic influence on a seam through tech-nology underground wells. To assess the effectiveness of the method of hydrodynamic impact on coal massif proposed two criteria: the amount of coal extracted from the well and the coefficient of degassing. The region of application of the method of degassing and gas-dynamic activity to reduce the steep outburst coal seams.

Keywords: degassing, pressure, technological well, the hydrodynamic impact, the efficiency criterion.
