针对新集三矿极软岩巷道具体条件 ,分析了巷道破坏原因和锚注加固机理 ,通过FLAC数值模拟和实验室试验进行了锚注参数设计 ,工程应用实践表明 ,锚注参数设计正确 ,锚注加固效果明显 ,取得了显著技术经济效益
According to the specific conditions of soft rock roadway in Xinji No.3 Mine, the cause of roadway destruction and the mechanism of bolting and grouting are analyzed, and the parameters of bolting and grouting are simulated by FLAC numerical simulation and laboratory tests. The engineering practice indicates that the design of bolting parameters is correct, Note reinforcement effect is obvious, has made significant technical and economic benefits
