摘要
依据采矿设计理论与工程实践,针对综采放顶煤的端头放煤难题与区段煤柱问题,首次提出采用错层位巷道布置系统提高放顶煤回收率。
According to mining design theory and practice this paper aims at raising the recovery ratio by multiple ways,improving the things of coal quality and pointing out the difficulties of caving coal at the end and the problems of coal pillars in sublevels.This paper first puts forward a production system with arrangement of stagger position along roof and floor individually in coal face.
