摘　　要：针对岳城煤矿暗斜井在施工过程中,支护结构复杂、严重影响暗斜井掘进效率的现状,提出了采用锚、网、喷组合系统补强支护方案,解决了支护效率和支护强度的冲突。自该方案应用以来,支护效率提升37.2%,支护强度提升2.6%,在确保支护稳定的情况下提升了暗斜井的掘进效率。Aiming at the complex supporting structure and the serious influence on the tunneling efficiency of the dark inclined well in Yuecheng Coal Mine,the reinforcement support scheme of bolting,netting and shotcrete combined system is put forward to solve the difference between the support efficiency and the support strength conflict.Since the application of this scheme,the support efficiency has been increased by 37.2%and the support strength by 2.6%.The tunneling efficiency of dark inclined wells has been improved under the condition of ensuring the stability of the support.
