摘要
以上社煤矿西翼运输大巷全煤巷道为工程实例,巷道原锚杆锚索支护系统无法有效控制围岩变形,对巷道顶板及两帮进行锚网索再加固;试验表明,采用该支护方案可有效控制巷道围岩变形,效果良好。
Taking full seam gateway of West wing in Shangshe Colliery as engineering example, original bolt anchor and cable support system of roadway can＇t effectively control surrounding rock deformation so that cable anchor re-strengthening have been conducted in roadway roof and two gangs. Tests show that this support scheme can effectively control the deformation of the surrounding rock in the roadway, and achieves good effect.
