摘要

A method for degassing at coal extraction with underground method includes installation of degassing station with gas duct that provides removal of methane-air mixture from worked out space through branches, and from rock massif through wells, those are connected to the gas line. In the face additional gas line is laid, its suction section moves with following the executive device of the extraction combine with provision of removal of methane-air mixture and coal dust in the zone of destruction of coal seam at that, with supply of those to the main gas duct.
