FIELD: mining.
SUBSTANCE: invention relates to a powered support section with a coal discharge device. Said section comprises base, ceiling, hydraulic racks and lifting jacks. Overlap is made as composite, including base overlapping, rotary covering and shield, rotary covering is hingedly connected by one side with base covering, and the other – with shield. Base covering is connected to the base by means of hydraulic posts normally oriented to the base, rotary covering is connected to the base by means of hydraulic posts, pivotally fixed on the base with the possibility of rotation in the vertical plane to the bottomhole – from the bottomhole, the shield is connected to the base by the hydraulic ram, fixed on the base by means of the rotary hydraulic motor. At that, the outlet opening is formed by lowering the shield to the working soil, the chute functions as a rotary shutter, and the feeder – raising paws and a scraper reloader.
EFFECT: increased efficiency of the support section operation for coal output from the overlying massif into the working space and its loading into the vehicle due to transformation of the part of the composite elements into the receiving-loading zone.
