摘要
松峪煤业XV1302工作面回采期间通过大小断层共计6条,其中较为复杂的断层为FJ2正断层,断层落差达12 m,通过分析探讨,如采用“施工绕道甩构造”的方法,施工难度较高,耗费成本预计较大,而采取“浅截深、快拉架、速打护帮板”以及“对三角区采取挑木料支护的方式控制顶帮”的方式快速通过,缩短了施工时间,节约了成本,为类似工作面过断层积累了经验。
In view of the complexity and large drop of six faults in mining proces at XV1302 working face of Songyu Coal Industry Co.,Ltd.,the author propose the method of crossing the faults rapidly with shallow cutting depth,rapid shelf and side guard board setting,and top slope control by wood support in triangle zone,which can shorten the construction period,save the cost,providing the experience for crossing fault at similar working face.
