为获取深部围岩状况和地应力数据,以制定合理的支护方案,采用钻孔全景数字化探测分析技术对围岩结构进行了探测分析,采用流变应力恢复法对围岩应力进行了长期测试,获取了地应力数据,采用跨孔声波法对围岩松动圈情况进行了测试,获取了围岩及应力分布特征,探索了围岩破坏机理。并在现场采取锚网索、注浆锚索等多种支护方式,确定了适合一矿地质条件的支护方案和支护参数,保证了深部巷道支护效果,一定程度降低了支护和巷修成本。
In order to obtain the data of deep surrounding rock and ground stress, a reasonable support scheme was set up, and the surrounding rock mass was probed and analyzed by using the digital drilling sounding analysis technology. The stress of the surrounding rock was tested by using the method of rheological stress recovery , Obtained the data of the earth stress and tested the situation of the surrounding rock loose ring by using the transonic sound wave method. The surrounding rock and stress distribution characteristics were obtained, and the failure mechanism of the surrounding rock was explored. And in the scene to take anchor net, grouting anchor cable and other support methods to determine the geological conditions for a mine supporting programs and support parameters to ensure the effect of deep roadway support, to a certain extent, reduce the support and Lane repair costs.
