为了评价复杂地质区域矿产资源开发后的废弃物堆积场对地下水的影响,需要准确掌握区域地下水位在废弃物堆积场作用下的空间变化规律,为此提出了全隐式非构造网格有限体积(FVM)地下水模拟模型。在贵州某化工企业尾矿堆场的实际应用中,通过模拟成果与钻孔资料对比分析,验证了该数值模拟模的可行性与精度;通过有无尾矿堆场的模拟结果对比分析,弄清了尾矿堆场对区域地下水的影响情况。结果表明,基于非构造网格有限体积地下水数值模拟模型适宜于复杂区域内地下水模拟或污染源对地下水的影响评价。
【英文摘要】 To evaluate the influences of tailing stacks of mining industries on the groundwater in complicated geological regions,it is necessary to understand the spatial variations of groundwater under the impacts of the tailing stacks.The development of numerical models capable of reflecting the geological complexity,with high stability and accuracy is very important.Therefore,in this paper,a completely implicit finite volume method(FVM) based on unstructured grid systems has been proposed.A case study was carried ...
