对淮北芦岭矿软岩巷道进行了全面的测试 ,分析了巷道变形及底鼓的原因 ,确定了巷道围岩塑性区的参数 ,在此基础上计算和测试了巷道表面位移和地压
The soft rock roadway in Luling Mine in Huaibei has been fully tested. The causes of tunnel deformation and bottom drum are analyzed. The parameters of the plastic zone in the surrounding rock of the roadway have been determined. Based on this, the surface displacement and ground pressure of the roadway have been calculated and tested.
