Coal raking machine and coal mining method utilizing coal raking machine

Abstract

The invention relates to a coal raking machine and a coal mining method utilizing the coal raking machine. The coal raking machine comprises a driving part, a driven part and a transmission link part,wherein the transmission link part comprises an annular transmission chain which is detachably mounted at a raking head, and the two ends of the annular transmission chain are separately engaged withchain wheels of the driving and driven parts so as to achieve circulating reciprocating movement. During coal mining, interior of upper and lower gate roads is subjected to loosening-borehole-drilledexplosive-loaded blasting towards a coal bed of a working surface, thus, coal mass can fall into slotted holes, then, the driving part is started up, coal self-slides into or is driven to slide intothe lower gate road through the raking head and enters a scraper reloader for being conveyed away, then, the coal raking machine and the reloader are closed down, and the coal raking machine moves forwards under the drive of a hydraulic support for carrying out next circulating mining. The coal raking machine and the coal mining method utilizing the coal raking machine have the aims that the structure is simple, the operation is convenient, large-scale equipment is not required to be arranged in the working surface, and the unmanned mining of a working surface of a pitching coal bed can be achieved.

Description

technical field [0001] The invention relates to equipment for cutting or crushing ore-dropping devices during mining or quarrying, in particular to a coal-screwing machine used for mining inclined coal seams and a coal mining method using the same. Background technique [0002] In the underground mining of coal mines, due to the complex existence conditions of coal seams, the mining techniques are different. Steeply inclined coal seams have large reserves in my country. The southern and western regions have a large amount of steeply inclined coal seams. Some mining areas are mainly mining coal seams. Due to the depletion of resources, some old mining areas in the east are also facing the problem of steeply inclined coal seam mining. The traditional mining techniques of inclined coal seams mainly include blast mining, ordinary mechanized coal mining, comprehensive mechanized working face mining, and top-coal caving mining. However, in inclined or steeply inclined coal seams,...

AI Technical Summary

Problems solved by technology

However, in inclined or steeply inclined coal seams, the above-mentioned traditional mining methods have problems such as easy lodging of support equipment such as inclined supports for coal seams, difficulty in roof support, poor working conditions in the working face, narrow working space, and many safety hazards, making construction difficult. , which brings great difficulties to the mining of steeply inclined coal seams
