| Abstract: | Three-dimensional visualization modeling technique was used to build the geological model and project structure model of Dongguashan Copper Mine,and the 3d-models was applied to mechanics analysis models. The automatic grid partition of mechanics model was achieved by fitting block model to solid model,and the problem of numerical simulation for rock engineering under multi-medium and complex structure was resolved. Through analyzing the rock mechanics response of three different stope sequences, the optimum solution was ascertained. The results provide guidance for design and production of rock engineering. |
