The object of researches is processes flowing in the tense array saturated by gas at hydrodynamic influence. The purpose of work is working off the parameters of hydrodynamic influence for intensification of degassing and decline of danger of the sudden troop landings of the coal layer l7u-"Pugachivka-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 l7u-"Pugachivka-east" through two technological mining holes bored from one setting of machine-tool the dynamics of change of average daily concentration of methane in the mixture of gas and air 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 the mixture of gas and air in making taking into account a background one the coefficient of degassing of array is certain after his treatment through the technological mining holes, which is equal 31%, is certain. Efficiency of hydrodynamic influence as method of degassing and decline of dangers of the sudden troop landings in the affected zone of technological mining holes is set. HYDRODYNAMIC INFLUENCE, TECHNOLOGICAL MINING HOLES, AVER-AGE DAILY CONCENTRATION, DEFORMATION OF ARRAY, COEFFICIENT OF DEGASSING.
