FIELD: mining industry, possible use during underground extraction of coal beds with rock layers.
SUBSTANCE: in accordance to invention, a complex of panel or level mines is driven. Ventilation and transportation drifts are driven, in advance in space and time before cleaning operations, and also a divided furnace is driven with installation of cleaning equipment complex in it. From ventilation and transportation drifts, a rock layer is drilled out, produced rock in ventilation 8 and transportation 9 drifts is loaded into the pack. Coal is extracted.
EFFECT: increased intensiveness of cleaning operations, decreased impoverishment of coal by rock layers.
