摘要
针对3210运输巷碎裂顶板大断面巷道顶板容易出现碎裂变形,不能有效控制巷道围岩的变形,影响煤矿生产与安全问题,对原有锚网与锚索联合支护方案进行优化,优化后的支护方案可以控制围岩变形。
Aiming at the problem that the roof of the large section roadway of the broken roof of the 3210 transport roadway is prone to fracture deformation,which can not effectively control the deformation of the surrounding rock of the roadway and affect the production and safety of the coal mine,the original combined support scheme of anchor net and anchor cable is optimized.The optimized support scheme can control the deformation of surrounding rock.
