摘要
结合陕西明业煤矿实际状况,对巷道围岩支护等问题进行探究,在认知与分析支护原理及锚锚注浆机理的基础上,提出锚锚注联合支护技术,通过有效支护技术形成稳定结构,切实控制巷道围岩变形及应力问题,确保巷道运行的安全性。
Combined with the actual status of Mingye Colliery ,the author probes into the surrounding rock sup‐port and presents the combined support technology with bolt -mesh -anchor and grouting by analysis of the support principle and bolt -mesh -anchor and grouting mechanism ,which would control the surrounding rock deformation and stress ,and guarantee the roadway operation safety .
