The invention provides a fully-mechanized mining
gangue-throwing filling hydraulic support and a filling method thereof. The hydraulic support comprises a
gangue filling hydraulic support body withouta tamping mechanism, and a
gangue-throwing belt mechanism on the rear portion of the gangue filling hydraulic support body without the tamping mechanism. The gangue filling hydraulic support body without the tamping mechanism is composed of a front top beam, a rear
tail beam, a base, four stand columns, four connecting rods and a porous bottom-
discharge scraper conveyor, wherein the four stand columns and the four connecting rods are used for connecting the front top beam, the rear
tail beam and the base; and the porous bottom-
discharge scraper conveyor is hung on the rear
tail beam. The gangue-throwing belt mechanism consists of a rear seat, a vertical lifting oil cylinder, a
belt conveyor, a horizontal pulling and moving oil cylinder and a rear baffle plate, wherein the inclination angle of the
belt conveyor is 10-45 degrees. The filling method comprises the following steps that when
coal is
cut, a rear scraper gangue leakage hole of the filling hydraulic support is opened, the beltconveyor which is arranged behind the rear scraper gangue leakage hole is started, gangue falls onto the
belt conveyor from the gangue leakage hole, and a conveying belt rotates at a high speed to throw the gangue into a goaf for filling. According to the fully-mechanized mining gangue-throwing filling hydraulic support and the filling method thereof, tamping is replaced by throwing, the throwingdistance is long, the throwing height is high, the filling efficiency is high, and the fully-mechanized mining gangue-throwing filling hydraulic support and the filling method thereof are widely applied to the fields of
coal mine filling mining, gob-side entry retaining and the like.
