摘要
叙述了1015综采工作面当机巷掘进期间遇DF12(290°∠55°H=11 m)断层时,两巷调向31°平行布置,工作面回采过程中成功进行了调向旋转开采,提高了资源回收率,并保证单产水平基本不降低,具有较好的借鉴作用。
No.1015 mining face of Qinan Coal Mine meets the fault DF12(290°55°,H=11m).In this case,the direction of machine tunnel and ventilation tunnel is changed by 31°;the tunnels are arranged parallel;and the rotary mining method is adopted.In this way,the unit output of coal is not decreased while the coal resource is not wasted.This measure is referential to similar cases of other coal mines.
