The operation purpose - creation of elements of a recovery process of methane of carbonic fields with application PHDA. Methods of research - analytical, idealised, eksperimental. By means of mathematical modelling the algorithm of affecting on SMDBH with application PHDA and pneumodynamic affectings that has allowed to erect key parametres of process of affecting is erected. The applied device for pneumohydrodynamic affecting has allowed to vary in arguments of affecting and to institute the most effective. Experimental operations in conditions Public joint-stock company "Mine of A.F.Zasjadko" on PHDA through SMDBH MS-598, 1185-D and 1186-D where PHDA it was spent accordingly for 2 years, for 3 months and 2 months prior to an underworking of wells by coal-face works. Thus the production rate of wells has accordingly compounded 24,5, 17,15 and 32,4 thousand m3/days has been accordingly mined 30,23, 12,2 and 2,01 million м3 methanes. The total amount of mining of methane from six SMDBH has compounded 127, 63 million м3 methanes. Following regularity is erected: - at cyclic pneumohydrodynamic affecting on the snubed hills the gas emission from wells is observed right after affectings, and at affecting on not snubed massif - after approach to them of stopes of longwalls for spacing interval to 30 m and after a massif underworking for spacing interval from wells to 50 m (irrespective of a time of its conducting); - effective joint place near drainage bore-holles filtration bulk with filtration bulk of a snubed massif and an offset clogging materials in SMDBH originates at reversal loads to a stress differential P = 0,4-0,6MPa on clogging filtration bulk and at a pressure release time t = 10-18 minutes; - at conducting of pneumohydrodynamic affecting with magnification of quantity of cycles of affecting the permeability coefficient of a massif and velocity of return filtering of fluid are augmented, and the time of return filtering of fluid is diminished on quadric dependence. Сonditions of application of a way PHDA, arguments of process of affecting, yardsticks of performance and production engineering members are instituted. The erected elements of production engineering have allowed to elaborate the profile of the organisation of operations on PHDA and overall economics. Actual economic benefit of application PHDA has compounded 1 million 215 thousand grivnas in a year on one SMDBH, and communal economic benefit of 23 million 364 thousand grivnas BUBBLE-POINT BENCH COALS, THE SURFACE METHANE DRAINAGE BOREHOLES, SNUBED, THE PNEUMOHYDRODYNAMIC AFFECTING, NOT SNUBED MASSIF, THE DEBIT GAZA, VELOCITY OF THE GAS EMISSION, PRODUCTION ENGINEERING MEMBERS.
