摘要
锚杆网在井巷工程中应用广泛,而锚杆网要达到有效持久的防护作用,关键是施工之前,要对目标作业区域巷道顶板构造岩性进行全面勘察和分析论证,证明其可行性,这样才能使锚杆金属网的安全防护效果达到最佳。
The anchor-net is widely used in tunnel support.To ensure the long-term stable performance of such support,the practicability of the support must be well known through comprehensive investigation and analysis of lithologic characters of tunnel upper plate.
