摘要
新桥煤矿采煤工作面通过对遇到大倾角时提高煤炭资源回收率的研究,缩短了过断层时间,很大程度上避免了因工作面搬家而导致的安全隐患,丰富了综采工作面过大断层施工及技术管理经验,具有显著的经济及社会效益。
The technical scheme of working face with large inclined angle mining through the fault was studied to improve the recovery rate of coal resources in Xinqiao Coal Mine, and shorten the time of fault, to a large extent which avoid the hidden dangers caused by moving, enrich the fully mechanized working face fault construction and technical management experience, has the remarkable economic and social benefits.
