摘要
为了保证掘进巷道安全快速过断层,提高巷道过断层期间煤柱回采量,大同煤矿集团大斗沟煤业有限公司对三盘区5201巷传统过断层施工工艺存在的问题进行分析,提出了反掘法过F1断层,通过实际应用,取得了显著成效。
In order to ensure the safe and rapid crossing of faults in driving roadways and increase the recovery of coal pillars during the passing of faults,Dadougou Coal Industry Co.,Ltd.of Datong Coal Mine Group analyzed the problems existing in the traditional crossing faults construction technology of 5201 roadway in No.3 panel,and put forward the reverse excavation method for crossing F1 fault.The practical application show that remarkable results have been achieved.
