Abstract

The invention relates to the field of coal mine timbering and particularly relates to a filling bag body, a timbering and filling column and a construction method. The filling bag body comprises a first flexible bag body, a second flexible bag body and a diaphragm, wherein the diaphragm is located between the first flexible bag body and the second flexible bag body, a steel hoop is sewed to the periphery or an interlayer of the second flexible bag body, grouting holes are respectively formed in the upper parts of the outer side walls of the first flexible bag body and the second flexible bag body, and an exhausting holes are formed in the top end surface of the first flexible bag body; through holes are formed in the diaphragm; and a plurality of hanging lugs are arranged in the peripheraldirection of the second flexible bag body. The timbering and filling column comprises a first strut section, a second strut section and the filling bag body, wherein the first strut section is constructed by a first rapid setting material, and the second strut section is constructed by a second rapid setting material. The working procedure for constructing the filling column by virtue of the filling bag is simple, the filling column is rapidly formed, and meanwhile, the heights of the first strut section and the second strut section can be precisely controlled.

Description

technical field [0001] The invention relates to the field of coal mine support, in particular to a filling bag body, a support filling column and a construction method. Background technique [0002] In the process of coal mining, empty roadways are often encountered in the coal seam of the working face. The problem of supporting the coal seam roadway in the working face has always been a difficult problem in China. Seriously, accidents such as side slabs and roof fall of the mining face will occur, and serious cases will lead to accidents such as roof leaking, crushing or falling of the working face roof, which will cause a very large passive situation for underground safety production. [0003] At present, the solutions at home and abroad mainly include: (1) use dense monomers or wooden piles to strengthen the roof support of the tunnel; Full filling with high-water materials; (4) Rearrange the working face with the empty roadway as the cut eye. Dense monomers or wooden s...
