Abstract

The invention belongs to the field of coal exploitation filling, is applicable to filling of high-water materials and in particular relates to a moveable type mechanical seal filling exploitation bracket. The moveable type mechanical seal filling exploitation bracket comprises a hydraulic bracket, wherein the rear red of the hydraulic bracket is connected with a vertical retaining wall of a hard plate through a transverse beam; an upper flexible sealing block and a lower flexible sealing block are arranged between the vertical retaining wall and the hydraulic bracket; two sides of each flexible sealing block are contacted with the vertical retaining wall and the hydraulic bracket; a double-head hydraulic oil cylinder is arranged between the two flexible sealing blocks; and two piston rods of the double-head hydraulic oil cylinder are connected with the two flexible sealing blocks. In the device, the vertical retaining wall at the rear end of the hydraulic bracket is used as a filling retaining wall, so the labor force (for building the retaining wall or a hanging bag) in the traditional filling process is saved, cost is low and filling efficiency is high. Displacement of the upper flexible sealing block and the lower flexible sealing block is adjusted by the hydraulic oil cylinder, so the flexible sealing blocks are tightly contacted with a top plate and a bottom plate, and filling sealability is guaranteed. Surrounding rock breakage and surface subsidence are controlled well in the mode of exploiting and filling at the same time.

Description

technical field [0001] The invention relates to a mobile mechanical seal filling mining support, which belongs to the field of coal mining filling and is suitable for filling high-water materials. Background technique [0002] At present, coal mining methods in the field of coal mining can be divided into three types according to the way of goaf processing: caving method, coal pillar method and filling method. Among them, the filling coal mining method refers to a coal mining method in which relatively cheap filling materials are used to fill the goaf densely during or after the mining of the working face. Its purpose is mainly to use the filling body to control the surrounding rock, so as to reduce ecological and geological disasters such as surface subsidence and floor water inrush. At the same time, create safer operating conditions for the mining face. In the process of filling and mining with high-water materials, due to the strong fluidity of high-water materials, it...
