FIELD: mining.
SUBSTANCE: method involves formation of lower slashing of formation by means of a plough unit with movement into it of a hauling conveyor, cutting in bottom-hole massif of a rear vertical slot and a slot that is upper along the boundary with the roof, which are longitudinal throughout the face length, lowering of the massif onto the conveyor, splitting of a mineral into slabs, output of the mineral from the face in slabs, their lowing into trolleys and locomotive haulage to a bulk material crushing chamber. In the massif settled down on the conveyor there cutout are inclined transverse slots splitting the massif into inclined layers that are then transferred to horizontal position for splitting of the mineral into slabs. Cutout of vertical transverse slots is performed using a motor-driven multi-jib machine.
EFFECT: high efficiency of a mining face, maximum extraction of mineral deposits from the formation being developed, extraction of methane from the produced mineral, safety of second working as per gas factor and sanitary-hygienic conditions of underground production as to dust.
