Abstract

The invention discloses underground filling equipment, an underground filling system and an underground filling method. The underground filling equipment comprises a filling mold frame and an inflatable bag supply device used for supplying inflatable bags into the filling mold frame; the rear portion of the filling mold frame is provided with a mold frame rear opening, and the front portion of thefilling mold frame is provided with at least one mold frame front opening used for clamping the inflatable bags; the inflatable bag supply device is located on the front side of the filling mold frame; and the inflatable bag supply device can process non-inflated and continuous bag barrels into the inflatable bags and push the inflatable bags into the mold frame front opening, and the inflatablebags can seal the mold frame front opening. According to the underground filling equipment, the underground filling system and the underground filling method, the inflatable bags can be added into a filling body, so that a hole is formed in the filling body, the filling material is saved, and the filling cost is reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine goaf filling, in particular to an underground filling equipment, an underground filling system and an underground filling method. Background technique [0002] In the process of coal mining, a goaf will be formed behind the hydraulic support of the working face. In order to avoid the collapse of the goaf and affect the surface, the goaf is generally backfilled, and the filling material is used to form a filling body to support the ground. The gap between the bottom plate and the roof of the goaf can effectively avoid the collapse of the goaf and protect the ecological environment on the surface. [0003] In the prior art, when backfilling the goaf, the filling body is a solid structure, which requires a large amount of filling material, which is not conducive to reducing the filling cost. Contents of the invention [0004] The object of the present invention is to provide an underground filli...
