The invention discloses a large-mining-height front and rear top beam coaxial articulated fill coal mining hydraulic bracket, which comprises a front canopy, a front top beam, a rear top beam, a front stand column, a rear stand column, a three-mechanism coaxial articulated shaft, a four-link mechanism, a compactor mounting platform, a compactor, a rotary jack, a slide way, a pulling jack, a solid fill mining conveyer and a base, wherein the front top beam is supported by the front stand column; the rear top beam is supported by the rear stand column; the front top beam, the four-link mechanism and the rear top beam are articulated at the three-mechanism coaxial articulated shaft; the pressure of a top plate on the rear part of the bracket is borne by the rear top beam; the solid fill mining conveyer can be suspended by the rear top beam; the rear top beam is provided with the slide way and the pulling jack; and a filling material can be compacted by the compactor consisting of a telescopic oil cylinder and a compacting plate on the compactor mounting platform on the rear part of the base. According to the bracket, a coal mining space can be provided for a large-mining-height working face with mining height of 4.5-6.0 m and a fill goaf can also be compacted. The large-mining-height front and rear top beam coaxial articulated fill coal mining hydraulic bracket has the advantages of rational structure, high strength and high adaptability.
