FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used for mining. The method of methane capture during mining of coal layers by a power mining complex comprises the mining of a coal layer using the sections of a powered roof support with box-shaped top covers of a face conveyor and combine. Simultaneously with coal extraction, transportation through a face and preparatory developments, through the holes in the box-shaped top covers and telescopic branch pipes methane is pumped out. From a production face all box-shaped top covers of sections are joined among themselves with corrugated branch pipes of a certain length equal to an advance increment of the powered roof support.
EFFECT: invention allows to implement the comprehensive and rational coal use in subsoil due to efficient by-product extraction of methane, reduce net cost of coal, provide safe mineral development.
