The reduction method for natural methane carriage of coal layers includes sinking from earth surface of producing wells and initiating well, creation of the coal methane production by initiating wells with cavitation forming and created fracture for pressurized fluid pumping-in to basement rocks and are covered coal layers. The blasting chargers, ballistic rocket fuels, gun powder are located after blocked entry of coal methane to producing wells in result of vibratory action of fluctuating hydrodynamic sources to a corresponding hydrodynamic system connected to them in producing well areas being in the coal layer or pumped down to the inflammable-oxidation mixtures initiating location initiators in them - electric detonators, explosive cartridges or electric igniters. Initiation can be simultaneous or millisecond-delay. Then vibratory action of fluctuating hydrodynamic sources connected to them a corresponding hydrodynamic system up to further blocked entry coal methane to producing wells. |
