Numerical Analysis on the Failure Mode of Stage Backfill Stope due to Mining Disturbance

Abstract:

Based on engineering background of Hemushan iron mine, the stress state, the displacement deformation and the plastic zone changes characteristic of backfill stope during different excavation processes are simulated. The results show that the maximum excavation effect domain happens around the surrounding rock and panel pillars. The vertical displacement of the room roof increases during excavation processing. The ore-body adjacent to the mined out area leads tensile failure trends. The tensile and shear zone dominates the room roof rock, and the support pillar is under shear significantly. The failure mode of SBF stope is obtained
