Hydraulic support for filling waste rock

Abstract

A gangue filling hydraulic support for fully mechanized mining face in coal mines, comprising a top beam (1), a column (2), a base (10), a tail beam (3), a tail beam jack (7) and a tail beam (3) The bottom hanging scraper conveyor chute (6) etc. constitutes. The groove plate of hanging chute (6) has gangue leakage hole (12). The filling bracket is arranged on the fully mechanized mining face, and the suspension chute (6) is sequentially connected, and is connected with the fully mechanized mining face, the tail and the head of the lower end to form a whole scraper conveyor (26). In addition to being used as support equipment for fully mechanized mining, the filling support is also the main component of the gangue filling system. In addition to the common filling methods, the filling system has the advantages of disposing of gangue underground, reducing transportation and lifting, reducing ground subsidence, reducing land occupation and pollution of gangue hills, and has the advantages of simple system, less equipment, uncomplicated technology, and low investment. less, unaffected by frame shifting, and can be bent and transported uninterruptedly to fill gangue.

Description

technical field [0001] The invention relates to a hydraulic support for fully mechanized mining support equipment in coal mines, in particular to a gangue filling hydraulic support for directly filling gangue from a driving face into a goaf of a fully mechanized mining face underground. Background technique [0002] Gangue is the associated waste in coal production and processing. A large amount of gangue has been piled up for a long time, occupying land, causing spontaneous combustion, and polluting the air and groundwater. The mined-out area of ​​the mining face is the largest underground space that can accommodate gangue, and it is the most economical and reasonable solution to dispose of gangue in the goaf. Backfilling the mined-out area can not only prevent gangue from going into the well, occupy no land, reduce environmental pollution, but also reduce surface subsidence and greatly liberate coal reserves. At present, there are two filling methods: hydraulic and wind, ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing gangue filling hydraulic support that needs to be equipped with special filling equipment, large investment, complicated technology, and high cost, the present invention provides a new gangue filling hydraulic support. In addition to a series of advantages of not going into the well for backfilling of excavation gangue, it also has the characteristics of less configuration equipment, simple system, uncomplicated technology, less investment, not affected by frame shifting, and can be bent to transport gangue
