The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.
