The object of researches - the processes descending in at borehole zone bubble-point coal pedigree block at pneumohydrodynamic impact. Subject of researches - parameters of process of pneumohydrodynamic impact on a mining massive through surface methane drainage boreholes. The labour purpose consists in optimisation of parameters of pneumohydrodynamic impact on a mining massive through surface methane drainage boreholes that will allow to increase production of methane from surface boreholes. Researches methods - analytical, idealised, experimental in industrial conditions. The control algorithm by pneumohydrodynamic impact process with allowance for flows of fluid in boreholes is developed at a pressure release. It is established, that fluctuation of a permeability coefficient of a block and rate of return filtering from quantity of the executed cycles is presented by exponential functions, and a delta time of return filtering in the course of effect - logarithmic. The effectiveness criterion of effect defined by fluctuation of a growth form of a borehole pressure at a puffing on linear and decrease of as much as possible created value of pressure less 1 MPa is established. The experimental jobs on boreholles ZD-5, D-5, ZD-2, the MT - 340 have been conducted. As a result of the conducted jobs had a practical importance confirmation of an effectiveness criterion. Effect leading particulars is established: excess of fluid level over perforation level, a time and delivery pressure, a time of a pressure release and a cycling. The procedure of commercial tests of a method of intensification of degassing of a block is developed by pneumohydrodynamic impact.
