摘要: 本文以唐口煤矿深部软岩巷道为研究对象,在总结了巷道现场破坏特征的基础上,分析了软岩巷道的特点和变形破坏的原因,以南部轨道大巷为试验段进行数值模拟,提出了以普通锚网喷+注浆加固围岩为主体的支护方案,现场应用的效果良好,为深部软岩大变形巷道支护提供了有效的方法。Abstract: JPThis paper,based on Tangkou deep mine soft rock roadway,analyzes the reasons of roadway deformation and failure phenomena based on roadway failure characteristics;puts forward a program based on numerical simulation results of south roadway of the track that use bolt mesh and shotcrete + grouting to reinforce surrounding rock.The field application,which provides an effective method for the support of deep soft rock roadway,achieves good results.
