摘要
以古书院矿西三盘区水仓超高软岩巷道为研究对象,应用高强度、高刚度、高可靠性与低支护密度的"三高一低"的现代锚杆支护设计理念,对巷道支护材料、支护参数进行合理选择。通过采用高预应力锚杆锚索、注浆、喷浆联合支护方式,达到了有效控制巷道围岩变形、提高围岩完整性和稳定性的目的。
Taking super-high soft rock roadway of western 3 area in Gushuyuan Mine as an example,the new bolt supporting design concept of ＂ three high and one low＂ which has the virtue of including high strength,high rigidity,high reliability and low density has been applied to make a reasonable choice on supporting material and supporting parameters. Through the application of comprehensive supporting methods combined with high pressure bolt and anchor, grouting and guniting, the purpose of controlling roadway surrounding rock deformation, improving the integrity and stability of surrounding rock have been achieved.
