| Abstract: | The convergent observation method was used to monitor displacement variation status of surrounding rock after excavation of level tunnel in the mining area of an iron mine.A finit element model of level tunnel in the mining area was established to simulate stress and strain status of the surrounding rock after excavation of the tunnel.Contrast of tunnel deformation monitor values and data simulation results verified the results of deformation mechanism of the surrounding rock. |
