摘要
为解决复合顶板下巷道围岩控制难题,以慈林山煤矿9107运输巷为工程背景,采用理论计算、数值模拟、现场试验的方法,计算并确定了锚杆索长度,设计了支护方案。支护参数和方案应用后,监测了巷道围岩变形情况,证明了支护参数的合理性。
In order to solve the problem of surrounding rock control of roadway under composite roof,taking the 9107 transportation roadway of Cilinshan Coal Mine as the engineering background,the length of anchor cable is calculated and determined by theoretical calculation,numerical simulation and field test,and the supporting scheme is designed.After the application of support parameters and scheme,the deformation of surrounding rock of roadway is monitored,and the rationality of support parameters is proved.
