| Abstract: | Based on the pillar status of Jinshandian iron mine in WISCO, the feasibility scheme of the pillar mining is simulated by using elastic-plastic finite element theory and the stability of the surrounding rock and surface among the mining process by different scheme is analyzed. Based on all summaries about the pillar mining strata movement and surface deformation law, the damaged area in the surface during Jinshandian pillar mining with different mining schemes is delineated. Then, the reasonable pillar mining scheme is determined. |
