Abstract. A new method is proposed for improving energy efficiency and safety of the degassing system. A special technology is described for methane recovery from the exhaust rock mass, and new technical solutions are presented for reconstruction of surface degassing, which exclude emissions of the recovered methane into the atmosphere and underground tunnels. The mine degasification systems, intensification of methane recovery from the coal deposits, methods for the methane accident-free transportation by underground and surface pipelines, as well as methane utilization were analyzed. It is concluded that ensured safety of methane-recovery operations can be provided by a single technological process, which includes methane recovery, transportation and utilization. The most effective technology is chosen for recovering methane from the undermined rock mass, which applies method of pneumohydrodynamic action on the non-disturbed massif. Special technical solutions are developed for reconstruction of existing surface gas transportation system, which improve its energy efficiency and safety of operation, and which assume connection of the wells through the gas control points of gas preparation and their introduction into the gas transmission system of the turbo-expander station.
Keywords: methane, methane recovery, degassing well, gas transportation.
