通过对彭庄矿某交叉点加固方案的探讨,分析在裂隙发育、地下水丰富且含有膨胀性矿物的砂岩巷道中采用锚注技术作为支护方案时的可行性及其支护机理。应用FLAC~(3D)软件分析对比注浆加固前后巷道的变形状况,肯定了注浆加固方案的支护效果。
Through the discussion of a reinforcement project at a crossroad in Pengzhuang Mine, the feasibility and the supporting mechanism of the application of bolting and grouting technology in sandstone tunnels with fissures, abundant groundwater and expansive minerals are analyzed. FLAC 3D software was used to analyze the deformation of the roadway before and after the grouting reinforcement and affirmed the supporting effect of the grouting reinforcement scheme.
