基于古书院矿3号煤一直采用掘巷的方法回收,该方法资源回收率低、安全系数低、回收速度慢,影响到下组煤9号煤的回采、回收成本高的情况,根据矿井生产情况,尝试采用闲置的3号煤普通综采设备进行简单改造来回收该段煤柱,实现了此煤柱的安全快速回收.“,”Based on the No. 3 coal of Gushuyuan Mine had been extracted by roadway driving, the resource recovery rate was low, and with low safety coefficient, slow recovery. The mining method affected the No. 9 coal mining recovery, its recovery cost was high, according to the mine production situation, spare ordinary coal seam fully mechanized equipment for simple modifications to the recovery of the segment was tried out, which realized the safety of the coal pillar quick recovery.
