【摘要】 以新邱南部矸石山为例,建立了矸石山淋溶液中硫酸盐对地下水污染的地下水流动模型和污染物运移模型,通过SOM法进行数值求解,利用该数值模型对淋溶液在地下水中迁移行为进行模拟,预测了污染物浓度的时空分布特征.对污染晕的大小、分布范围进行了数值模拟,并结合实际观测数据进行对比分析.结果表明,污染物浓度变化趋势及计算值与监测结果基本吻合,从而验证了模型的可靠性和实用性.更多还原

【Abstract】 Taking the waste rock hill in Xinqiu as an example, the numerical model of groundwater flow and contaminant migration is established. The coupled model is numerically solved by SOM method, which predict the temporal and spatial distribution features of contaminant concentration. Additionally, the visualization of the pollution halo areas and distribution range are presented. The result indicates the concentration of contaminates agrees well with the measured values, thus it verifies the model is reliable and practical.更多还原
