The work purpose - are parameters improvement arguments of pneumohydrodynamic influence (PHDI) for influx intensification of gas in surface methane drainage borehole and development standard of organization of Ukraine "Rules of support of hydrodynamic influence for decrease of gasdynamic activity of flat at realisation of development workings". Methods of researches - analytical, mining experiment, a statistical analysis. Specifications on development of a method of support of hydrodynamic influence for decrease of gasdynamic activity of flat at realisation of development workings. Mathematical model PHDI allowing for a nonstationary flow pattern of fluid is developed. This model considers PHDI process on massive with allowance for numerical parameters pneumoeffect. Algorithm PHDI is developed, conditions of usage of method PHDI, and also critical parameters PHDI are established. The experimental work in industrial conditions on through surface methane drainage borehole on a seam m3 Rented enterprise "Mine of A.F.Zasjadko" through the wells earned additionally by longwall are conducted. It is established, that is time-invariant PHDI there is a methane emission from surface methane drainage borehole at approach of working faces for spacing interval to 30 m and after a distance of working faces apart more than 50 m. Outcome PHDI is: goaf degassing, a load increase on a working face, rise job safety of miners, decrease of outbursts of methane in an aerosphere.
