摘　　要：为了加快综采工作面过断层速度,提高断层破碎带处顶板稳定性,保证工作面液压支架支护效果,降低机械设备故障率,大同煤矿集团燕子山矿通过技术研究,对8210工作面采取导硐法过F2断层,并采取了"注浆+恒阻锚索+迈步式锚索吊棚"等联合支护措施对导硐顶板进行支护,通过实际应用,取得了显著成效。In order to build up the cross-fault speed of fully mechanized mining face, improve the roof stability at the fault fracture zone, ensure the effect of hydraulic support and reduce the failure rate of mechanical equipment, Yanzishan Coal Mine of Datong Coal Mine Group used a pilot tunnel method to cross the F2 fault in the 8210 working face through technical research, and adopted "grouting + constant resistance anchor cable + step-by-step anchor cable hanging shed" and other combined supporting measures to support the roof of the pilot tunnel. Practical application shows that the results are remarkable.
