Equipment arranging system for three-soft coal bed stope face

Abstract

The invention discloses an equipment arranging system for a three-soft coal bed stope face. According to the equipment arranging system, on the basis of a traditional stope face, a machine roadway anda track roadway are exchanged, the machine roadway serves as upper crossheading of a coal mining system, the track roadway serves as lower crossheading of the coal mining system, so that in the production process, accumulated water of a goaf can be smoothly discharged without influence of large equipment such as a transfer machine, a crusher and a belt machine, and meanwhile, the transfer machine, the crusher and the belt machine cannot be influenced by the water in the equipment pulling and moving processes, and the situation that the equipment cannot be pulled and moved is avoided accordingly to ensure normal operating of the equipment.

Description

Technical field [0001] The present invention relates to the technical field of coal mining equipment, and in particular to an equipment arrangement system used in a three-soft coal seam mining face. Background technique [0002] The three-soft coal seam is a kind of western Jurassic coal seam, which is characterized by deep burial, late diagenesis, loose rock structure, mainly mud cement, rich in clay minerals such as kaolinite and montmorillonite, and low strength After encountering water, it is easy to swell and disintegrate, and the sludge phenomenon is serious. When subjected to mining pressure, the rheological phenomenon will be aggravated, resulting in poor stability of the roadway, large deformation, high rate of disrepair, and difficult maintenance. With the continuous development of coal resources, more and more mines have entered the deep three-soft coal seam for mining, and the characteristics of the three-soft coal seam are quite different from traditional mining coal...

AI Technical Summary

Problems solved by technology

[0002] The third soft coal seam is a western Jurassic coal seam, which is characterized by deep burial, late diagenetic age, loose rock structure, mainly argillaceous cementation, rich in clay minerals such as kaolinite and montmorillonite, and low strength It is easy to expand and disintegrate when exposed to water, and the phenomenon of muddying is serious. When it is subjected to mining pressure, it will intensify the rheological phenomenon, resulting in poor self-stabilization ability, large deformation, high rate of disrepair and difficult maintenance of the roadway.
