FIELD: mining industry. SUBSTANCE: this can be used for relieving from rock pressure, protection and degassing of outburst-risky and gas-bearing seams. Degassing method implies driving of drainage working in roof and foot of gas-bearing seam prior to start of driving development workings in seam being protected, and installation of temporary support in working. Drainage working is driven at distance from seam being protected not exceeding 8.5-fold width of drainage working. Placed on its foot is perforated gas pipeline, then working is caved. Driving of development workings in protected seam is initiated after reduction of gas-bearing capacity of section being degassed to safety level. EFFECT: high efficiency. 2 cl, 2 dwg
