FIELD: mining.
SUBSTANCE: method includes drilling from day surface of vertical degassing wells until crossing with coal bed. Inclined degassing wells are drilled by rising and falling of coal bed. After that horizontal degassing wells are drilled in run of coal bed. Then in all degassing wells a hydraulic rupture is carried out via distance, which is identified experimentally for each coal bed. Mouths of degassing wells are connected to gas suction plants. Produced methane-air mixture is cleaned from water and other admixtures liquefied and pumped into reservoirs for storage.
EFFECT: improved gas recovery of degassing wells, improves safety of mining works performance.
