| Abstract: |
| According to the habitat and the feature of pillar of 31-1# ore body in Mining and Mineral Processing Plant of Yunnan Tin Company Ltd, this paper selected nine recovery mining jamb programs, which were researched by numerical simulation of three-dimensional finite element combining with ground pressure and the recovery process control theory, combined with the calculated results, the recovery mining jamb programs were optimized, which has an important meaning and reference value to the actual project for the mine. |
