摘要
运用岩体声波探测技术测定了淮北芦岭煤矿巷道围岩松动圈 ,进行了围岩稳定性分类 ,为芦岭煤矿今后的巷道支护设计提供了依据 ,认为岩体声波测试是煤矿井巷工程地质研究定量化的重要手段 ,值得应用推广。
By means o Acoustic techmique measuring the tummel surrounding rock loose circle and stability classify in LuLing coalmine of HuaiBai.The data is supplied to desigming its tummel support from now on.Acoustic measurement is thought to be an important method for quantitarive stady of tunnel engineering,and deserving to be applied and spread.
