| description | The invention relates to the technical field of coal mining and discloses a hydraulic support for high-water cut and fill mining. The hydraulic support comprises a front top beam, a rear top beam, a length-changeable extension structure, a connection structure, a telescopic stand column, a base and a height-adjustable baffle structure. According to the hydraulic support, the front top beam and the rear top beam are integrated at the same base at the same time, the front top beam and the rear top beam are supported through the telescopic stand column, the front top beam can support a coal mining region and a coal wall, and smooth operation of the coal mining work is guaranteed; the rear top beam conducts supporting and cut and fill supporting on the top face of a goaf in the next process while conducting coal mining, and the baffle structure can isolate the goaf, so that high-water packing materials can achieve cut and fill forming in the goaf so as to form the thickness having the supporting function quickly, and the cut and fill effect is guaranteed; by means of the hydraulic support, the coal mining work and the cut and fill work are conducted at the same time, and the coal mining efficiency and the cut and fill efficiency are improved greatly. |
