摘要
忻州窑矿11-2#层西二盘区8939工作面为一孤岛综采放顶煤工作面。8939工作面回采过程中需要过空巷。在空巷支设五排(排间距为0.8m×1.0m)单体柱补强原支护措施,顺利完成了回采。利用KJ216A监测系统和YHY-60B矿山压力连续记录仪,对顶板进行监测和管理。
The 8939 working face in the west 2nd panning area of No. 11-2 layer of Xinzhouyao Coal Mine is an island fully mechanized top coal mining and caving working face. 8939 working face needs to cross the goaf in the process of mining.
