摘要
为了提高软岩巷道围岩控制效果,以小峪矿南翼回风大巷为研究对象,采用现场实测、理论分析方法对围岩变形进行分析,提出矩形钢管混凝土拱架+锚网索+注浆方案对围岩变形进行控制,现场应用后,顶、底板变形量为151 mm,巷帮收敛量为85 mm,取得较好效果。
In order to improve the surrounding rock control effect of soft rock roadway,taking the south return air roadway of Xiaoyu Mine as the research object,the field measurement and theoretical analysis methods are used to analyze the surrounding rock deformation,and the scheme of rectangular steel tube concrete arch+anchor mesh cable+grouting is proposed to control the surrounding rock deformation.After field application,the deformation of roof and floor is 151 mm,and the convergence of roadway side is 85 mm,which has achieved good results.
