Mining, filling and remaining integrated fully-mechanized coal mining gangue filling working face system

Abstract

The invention discloses a mining, filling and retaining integrated fully-mechanized coal mining gangue filling working face system which comprises a moving platform, a gangue blocking template, a snatching mechanism and a grouting unit, the snatching mechanism is arranged on the moving platform in a sliding mode, and the snatching mechanism comprises a base and at least two active telescopic rods with one ends hinged to the base; the other end of each driving telescopic rod is detachably connected with the waste rock blocking template, each driving telescopic rod can rotate relative to the waste rock blocking template, and the waste rock blocking template can stretch out and draw back; the grouting unit comprises a grout storage barrel, a grouting pump and a self-propelled hollow grouting anchor rod which are sequentially connected through a pipeline, grouting holes corresponding to the self-propelled hollow grouting anchor rod are formed in the gangue blocking formwork, and the self-propelled hollow grouting anchor rod can penetrate through the corresponding grouting holes. According to the invention, the advancing efficiency of the working face is improved, and efficient coal mining-filling-entry retaining is realized.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a system for filling and filling working face of fully mechanized gangue mining with mining and filling integration. Background technique [0002] The gangue-based solid waste produced by coal mining is mainly discharged directly from the ground for a long time, causing serious pollution to the air, water and soil in a large range of mining areas. At present, saving resources and protecting the environment has become a global consensus. The environmental standards and related requirements for the development of mining areas are becoming more and more stringent. The treatment of gangue and solid waste has become imperative. Eliminating the harm of gangue and the green utilization of gangue have become an arduous task for enterprises to solve. It is also an important technical research direction for green coal mining. The rapid development of gangue backfill mining technology in re...

AI Technical Summary

Problems solved by technology

[0004] Waste rock solid filling mining was originally developed by pressing coal under construction. With the country's in-depth promotion of ecological civilization construction in mining areas, more and more large-scale production and large-scale new mines are facing the problem of a large amount of gangue solid waste disposal. Filling The working face has a large amount of gangue filling and fast advancing speed. The existing gangue solid filling working face retaining process is complex, labor-intensive and low in efficiency, which cannot meet the requirements of fast advancing gangue filling working face
