摘要
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。
By discussing the reinforcement program of a junction at Pengzhuang mine,analyzed the supporting mechanism and the feasibility of using the bolt grouting supporting method in a groundwater rich and fracture development banded sandstone roadway containing hygro-expansivity mineral. To use the FLAC^3D software compared the strain of roadway before and after the grouting,affirmed the supporting effect.
