摘要
针对地下矿山采区稳定性数值模拟分析过程中存在的三维矿床模型建立以及单元网格划分等难点问题,提出利用三维矿山软件进行精细建模与数值模拟软件耦合的模式,简化复杂矿山地质条件下模型前处理过程的思路。利用3DMINE对地下矿山三维矿床模型进行精细建模,通过MIDAS GTS软件对精细建模得到的三维矿床模型进行单元网格的划分与材料组的分配,快速、准确地为采区稳定性数值模拟分析提供具有较高几何相似性的模型,采用具有较强计算能力的计算软件FLAC3D进行计算。这种耦合精细建模方式不仅简化了矿山采区稳定性数值模拟的前处理过程,提高了地下矿山采区稳定性模拟计算的准确性,同时也将不同精度要求的三维矿床模型用于数值模拟运算,拓宽了三维矿山模型的应用领域。
To solve the difficulties such as complex 3D geographical model building and model meshing of mining area sta- bility analyzing process in underground mine, a method which coupled fine modeling of 3D mine software with numerical software was proposed. The pre-processing of complex deposit model in underground was largely simplified by this coupled pattern. In the paper, the 3D mineral deposit model was fine built by 3DMINE, and was meshed and grouped in MIDAS GTS,which fast and accurately provided a high geometrical similarly model for stability analysis of mining area, then was calculated by FLAC3D. Not only did the coupled pattern simplify pre-processing of complex deposit model, but also the ac- curacy of stability analysis of mining area was improved. And at the same time, different accuracy 3D deposit model could be used in numerical calculating,which broaden the application zone of 3D mineral deposit model.
