煤矿大倾角综采工作面仰斜回采技术

Upward Inclined Mining Technology for Fully Mechanized Mining Face in the Coal Seam with Large Inclined Angle

实践表明,要想完成煤矿大倾角综采工作面回采工作,就需要对具体回采工作认真分析,同时,还应结合井下设备特点选择最适合的开采工艺,并做好工作面搬家准备、煤层变薄区的回采等,进行超前分析,从而能系统性完成开采工作。本文重点针对煤矿大倾角综采工作面仰斜回采技术进行分析、研究,以期能满足相关工作面的开采要求,解决开采难题,提高矿井开采质量。

The practice shows that in order to complete the mining work of the fully mechanized coal mining face with large inclined angle,it is necessary to analyze the concrete mining work carefully.At the same time,the most suitable mining technology should be selected according to the characteristics of the underground equipment.In addition,advanced analysis shall be made on the moving preparation of the working face and the mining of the coal seam thinning area,so as to systematically complete the mining work.This paper focuses on the analysis and research of the mining technology of the large inclined angle fully mechanized face,in order to meet the mining requirements of the related face,solve the mining problems and improve the mining quality.
