The invention relates to a hexastyle supporting type coal mining and filling hydraulic bracket which comprises a telescopic girder, a front top girder, a rear top girder, a front upright post, a middle upright post, a rear upright post, a four bar mechanism, a middle upper part compaction mechanism, a height-regulating jack, a lower box type compaction mechanism, a slide way, a pulling jack, a rear-inserting type top protection device, a filling and mining conveyer and a base, wherein the front top girder is supported through the front upright post and the middle upright post and maintains the balance through the four bar mechanism; the rear top girder is mutually hinged with the front top girder and supported through the rear upright post, bears the pressure of a top plate, controls the deflection of the top plate before filling and can overhang the filling and mining conveyer to realize filling solid fillers in a goaf; and the rear top girder is provided with the slide way and can maintain a working space for normal mining of a working surface, realize the full filling of the goaf and meanwhile compact the fillers by clean mining within a high range. The hexastyle supporting type coal mining and filling hydraulic bracket has compact structure, strong supporting force, convenient operation and good filling effect on the goaf and can adapt to the filling and the mining under a complicated geological condition.
