摘要

Usage: development of gas-bearing formations. SUMMARY OF THE INVENTION: Field prepare for mining excavation paired drifts. Vent next generation executed by the column is carried out at a distance of 10-20 m to produce an unsupported conveying waste column, which is isolated from the excavation by operating a jumper. After jumper pipeline connected to gazootsa- ik- installation and is performed removing a portion of the methane-air mixture gob executed by Post via goaf waste column and unsupported production conveyor in the direction of movement of the stope. 2 yl.
