The job purpose - perfecting of arguments of a method of hydrodynamic affecting on an intense bubble-point coal seams before its dissection. Methods of researches - analytical, mining experimental researches On the basis of mining experimental researches of processes of hydrodynamic affecting on coals seam m3 - "Tolstuj" m2 - "Tonkij" districts №42-1146 m and №41-1146 m before their dissection and gas-makings from treated zones after its realisation in a heel of the carbonic bands completed by the shield aggregate, it is defined a time history of mean diurnal concentration of methane in steam-and-gas mixture on return air of longwall and coefficients of intensification of degassing of a treated block. By results of fluctuation of mean diurnal concentration of methane in air return air with allowance for its background value and diurnal quantity of air to longwall return air radiuses of treated zones of the carbonic block, varying within the limits from 6 m to 14,4 m, and quantity of coal extracted from well indispensable for coercion of treated zone in not outburst-prone state are defined. Hydrodynamic affecting arguments on a bench coal before its dissection are established fixed: Quantity of technological wells, pieces.- 1; Pressure of process of effect, MPa.-.4-5; Quantity of the extracted coal from zone, %.- 2; Coefficient of degassing of treated zone.> 0,45; Dissection of coals seams m3 - "Tolstuj" m2 - "Tonkij" districts №42-1146 m and №41-1146 m intermediate crosscuts №7, №15 and №16 are conducted without tags of a development of gasdynamic effectses.
