| 摘 要： | 以云南某矿区为研究对象,在详细调查区域水文地质条件和已有资料的基础上,结合调查区监测井,利用GMS软件建立研究区域地下水水流场模型和溶质运移模型。模型计算了在合理误差范围内的水流场模型并预测了硫酸盐在持续泄漏730d、180d后切断泄漏源,硫酸盐的迁移过程。研究结果表明:随着持续泄漏时间的增加,调查区域北部边界附近受到污染的浓度越高、污染范围越广,超标的污染物在北部边界区域进入岩溶含水层,遇到岩溶带会加速污染物向下游运移,破坏下游水质、危及下游村庄饮用水安全。

| Abstract: | Taking a mining area in Yunnan Province as the research object,on the basis of detailed investigation of regional hydrogeological conditions and existing data,combined with monitoring wells in the investigation area,GMS software is used to establish groundwater flow field model and solute transport model in the study area.The model calculates the flow field model within the reasonable error range,and predicts the sulfate migration process when the leakage source is cut off after 730days and 180days of continuous leakage.The results show that:with the increase of the continuous leakage time,the higher the concentration of the pollution near the northern boundary of the investigation area is,the wider the pollution range is,and the pollutants exceeding the standard enter the karst aquifer in the northern boundary area.When encountering the karst zone,the pollutants will accelerate their migration to the downstream,which will damage the downstream water quality and endanger the drinking water safety of the downstream villages. |
