| Abstract: | The displacement field and stress field for five working faces were calculated for the dike of the Nansi Lake after mining and collapse by use of 3-D fast Lagrangian method,and the regions where cracks might occur were analyzed.The calculated results accord with the field data.Based on it,a predicting calculation was performed for two working faces to be excavated,providing a basis for sustainable and permanent reinforcement of the dike. |

| Keywords: | Lagrangian method 3-D explicit finite difference calculation of influence induced by mining crack dike |
