Study on the Technology Coefficient of Supporting for Deep Coal Mine Tunnels
To keep the stability of tunnel’s surrounding rock, and control the deformation of surrounding rocks and reduce the maintenance cost of tunnel in maximum, this article did the following aspects. Aiming at large pressure , large deformation , bad maintenance state in deep coal mine tunnel , joint cable anchor support technology is adopted , and the coordination deformation of tunnel is accomplished through anchor net-surrounding rock and its coupling with the anchor cable .Through the theoretical calculation and numerical simulation of cable anchor coupling support ,we determine reasonable technology coefficient of bolt supporting and verify the correctness of support coefficient by field observation.
