FIELD: mining.
SUBSTANCE: mechanised longwall set of equipment for mining comprises sections of a powered support, a hydraulic cutting cleanout machine with actuators and hydraulic cutting heads, joined via metal tubes with a water-supply manifold, a hydraulic booster, a plane with two drives and a plate conveyor with load-carrying plates on rollers, and also comprises a transshipment platform with a mechanised sliding bottom. At the same time the set of equipment additionally comprises a scraper conveyor and a hydraulic support "Sputnik" structurally connected to each other by advancing rams. At both sides of the plate conveyor there are channel guides installed to move coalcutters along them with cable handlers. Besides, the coalcutter installed at the face side of the plate conveyor has a vertical upward direction of a cutting jib in parallel to the face line, and the coalcutter installed at the goaf side of the plate conveyor has a direction of a cutting jib in the bed plane along its border with the roof. The hydraulic machine of the set of equipment is fixed in the end part of the longwall face at the side of the transport mine, and hydraulic abrasive jets work in the transverse plane perpendicular to the direction of cut coal body displacement.
EFFECT: higher efficiency of a mining face due to reduction of duration of a process mining cycle.
