Purpose of work is working off the parameters of hydrodynamic influence for intensification degassings and declines of danger of the troop landings of coal layer of l12-" Kyrpychevka- east". The methods of researches are mine experimental researches. On the basis of mine experimental researches of process of hydrodynamic influence on a coal layer l12-"Kyrpychevka- east" through two technological mining holes, bored in the distance 20 м from each other the dynamics of change of average daily concentration of methane in a mixture was certain, and also processes and terms of deformation of array in the affected zone of both mining holes. On results measuring of average daily concentration of gas in making taking into account a background one the coefficient of degassing of array after his treatment through technological mining holes, which is equal 30,2%, is certain. Efficiency of hydrodynamic influence as method of degassing and decline of danger of the troop landings in the affected zone of technological mining holes is set. HYDRODYNAMIC INFLUENCE, TECHNOLOGICAL MINING HOLES, AVERAGE DAILY CONCENTRATION, DEFORMATION OF ARRAY, COEFFICIENT OF DEGASSING.
