Abstract
The results are analyzed for industrial tests of timely degassing of seam d6 which indicate that, in the recovery of methane of high concentration (95–98%), the gas content of the seam and the hazard of methane outburst are reduced. The technical-economic performance of this method is evaluated, and means of reducing its cost are proposed.
