【英文论文摘要】 The wastes of mining resources development usually have varies of chemical compounds. Serious groundwater pollution problems will be resulted from the leakage of the waste deposition site if the deposition site is not treated adequately.Considering the complicated hydro-geological conditions within the range of impacts by the waste deposition site,an unstructured finite volume method (FVM) model was proposed in this study.To overcome the difficulties perplexed by the selection of time steps with the spatial scales,an completely implicit numerical scheme of FVM was adopted.A satisfactory result has been made in the application of the model to the evaluation of a tailings stack of a chemical plant on the groundwater in Guizhou province.
