| Abstract: | In consideration of excavating technological conditions of underground cavern of GeJiu Tin Mine of YunNan Tin Corporation,the non-linear three-dimensional finite element method to analyze the dynamic excavating process of underground cavern is used for optimization of excavating sequence. The results show that the differences of stability of surrounding rock mass are markable for different excavating sequences. |
