Research and Practice on Repair Scheme of High Pressure Roadway in Deep Shaft

郑庄煤矿西翼揭煤措施巷,受矿压影响巷道拱部浆皮开裂,局部形成大面积的网包。根据巷道拱顶开裂的原因和严重程度,分别采用锚网、注浆锚杆+锚杆、注浆锚杆+锚索支护方案进行补强支护,西翼揭煤措施巷得到了快速修复,做到了顶板安全可控,工时材料节约高效。

In the measure roadway of uncovering coal in the west wing of Zhengzhuang Coal Mine, the slurry skin of the arch of the roadway is cracked under the influence of mine pressure, and a large area of net package is formed locally. According to the cause and severity of the cracking of the arch roof of the roadway, the supporting schemes of anchor net, grouting bolt + bolt and grouting bolt + anchor cable are adopted respectively to strengthen and support,and the measure roadway of uncovering coal in the west wing has been repaired quickly, so that the roof is safe and controllable, man-hour materials are economical and efficient.
