The invention discloses a self compaction type rock filling hydraulic support comprises a base and a top beam, between the top beam and the base connected by a post, the top beam is arranged at the front end of the front beam and the top beam is provided with a scraper conveyor, the rear end of the top beam through the telescopic jack is connected with an inner telescopic extrusion shovel plate jack, the telescopic level settings of the base; the rear of the first and second compression jacks connected with the squeezing plate, the first level of extrusion Jack set. The invention solves the problem of the existing filling mining hydraulic support existing equipment can not guarantee the filling to the top and reinforce the poor strength, the realization of the gob roof of the high strength support the use of filling gangue, effectively eliminating the problem of ground subsidence, the destruction in the factory, the village relocation conditions under the safe mining of the part of the permanent coal pillar and the corners of coal and coal under buildings, improve the recovery rate of coal resources. The invention is also applicable to various solid fillings such as fly ash, river sand and loess.
