【摘要】 采用三维可视化建模技术建立了冬瓜山铜矿的地质模型和工程结构模型,采用实体模型与块段模型套合技术,并把所构建的三维模型应用到力学分析模型中,实现了力学模型单元网格的自动划分,解决了多介质复杂结构条件下岩体工程开挖力学响应三维数值模拟问题.通过对冬瓜山的3种回采方案的力学分析,确定了最优的回采方案,研究结果对岩体工程设计和生产具有指导意义.更多还原

【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.更多还原
