摘　　要：针对深井高地应力半煤岩巷出现的煤岩交界处折帮、底鼓强烈、围岩稳定性差、需多次支护的问题,以申南凹煤矿运输大巷为研究对象,采用理论分析和数值模拟的方法,对深井半煤岩巷破坏机理进行分析,提出高预紧力穿层锚杆+反底拱支护技术,并运用FLAC^(3D)对比分析新方案的支护效果。Aiming at the junction of half coal rock roadway with high earth stree in the deep well,side break, strong floor heave, the stability of the surrounding rock is poor and needs to be supported many times, taking Sherman＇ ao coal mine roadway as the research object, the theoretical analysis and the method of numerical simulation are used to analyze the failure mechanism of the half coal rock roadway in the deep well, and the support technology of the new pre - tightening force and the reverse arch support technology is put forward, and the support effect of the new scheme is analyzed by using FLAC3D.
