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

Embodiment Construction

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] in Figure 1~3 The gangue-filled hydraulic support of the present invention shown in is mainly composed of top beam (1), column (2), base (10), tail beam (3), tail beam jack (7), chute (6), front beam , Side guard beam and other components. The chute (6) of the scraper conveyor is suspended under the tail beam (3) by four suspension circular chains (4) connected to the suspension coupling seats (11) on both sides of the chute (6) and the trough plate (15) There is a gangue hole (14) for gangue discharge and filling.

[0026] After the gangue-filled hydraulic supports are arranged on the fully mechanized mining face, the chutes (6) suspended under the tail beam (3) of the gangue-filled hydraulic supports are sequentially connected in sequence, and are connected to the chutes (6) respectively arranged on the fully mechanized face and the low...

Abstract

A hydraulic frame for filling waste rock is composed of top beam, vertical column, base, tail beam, jack of tail beam and scraper conveyor chute suspended under tail beam. It is featured as opening waste rock leaking hole on frid of suspension chute, connecting suspension chutes to each other in sequence then connecting them with chute head and chute end at working face to form a complete set of scraper conveyor.

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 the gangue of a driving face into the goaf of a fully mechanized mining face underground. Background technique [0002] Gangue is an associated waste in coal production and processing. A large amount of gangue is piled up for a long time, occupying land, causing spontaneous combustion, and polluting the atmosphere and groundwater. The mined-out area of ​​the working face is the largest space that can accommodate gangue underground, and the disposal of gangue in the mined-out area is the most economical and reasonable plan. Backfilling the mined-out area can not only realize that the gangue does not go into the well and occupy no land, reduce environmental pollution, but also reduce surface subsidence and greatly liberate coal reserves. At present, there are two filling methods: hyd...
