| Abstract: | The enclosing rock stability of shallow coal bed three soft coal roadways under different supporting condition was carried out numerical calculation with the numerical calculation method.Through numerical modeling,compared with the deformation and stress fore and after excavation,the influences of anchor arm addition,array pitch of anchor arm and anchor wire addition to the tunnel stress and deformation were discussed,which provide guiding function to the field supporting technology reformation. |
