综采工作面两巷及端头的支护与管理方法研究

针对煤矿综采工作面两巷及端头的支护与管理问题,以余吾矿为例,首先介绍了综采工作面概况,其次分别对运输顺槽和回风顺槽的掘进支护措施、超前支护措施及顶板开裂情况下的特殊支护措施等进行了研究,再次分析了工作面上下端头的支护方式和注意事项等,最后提出了综采工作面两巷及端头的矿压和变形监测方法。

Research on Support and Management Methods of Two Lanes and Ends in Fully Mechanized Mining Face

Aiming at the problems of support and management of the two lanes and ends of the fully mechanized mining face,this paper took Yuwu Coal Mine as an example,firstly introduced the general situation of the fully mechanized mining face,then studied the driving and supporting measures of the transport and return air chute,the advanced supporting measures and the special supporting measures under the condition of the roof cracking,and then analyzed the supporting methods and precautions of the upper and lower ends of the working face,and finally put forward the monitoring methods of the mine pressure and deformation of the two lanes and the ends of the fully mechanized mining face.
