Abstract

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.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a hydraulic support for high water filling mining. Background technique [0002] In the field of coal mining, from the long-term consideration of environmental protection and benefit improvement, the cement pipeline is filled under the mine after mining. Land and farmland are very conducive to environmental protection and provide technical equipment guarantee for the safe production of coal mines. [0003] Both mining and filling require roadway support, which is the key equipment for comprehensive mechanized coal mining, and the new coal mining technology of using roadway support for filling is only in the initial stage in our country. At present, the commonly used roadway support structures and functions are relatively single, and they cannot be filled at the same time during coal mining, and coal cannot be mined during filling, which seriously restricts the mining progres...
