| 摘 要： | 煤矸石淋溶液的地下迁移严重影响了地下水水质,对人类的生命构成了威胁.本文研究了煤矸石在降水淋溶和地下水迁移条件下,污染物在地下土层和岩层内的迁移规律.通过对阜新新邱南露天矿矸石山淋溶液中主要污染物离子(Ca~(2+)和Mg~(2+))迁移规律的数值模拟,得到特征截面的污染物浓度变化曲线和地下水迁移的水头压力曲线,其结果对水污染治理有一定的指导意义.

| Abstract: | The transport of coal gangue leachate influences the undergroud water quality and poses a threat to humanity. Considering the condition of leaching and undergroud water transport, this paper studied the transport rule of contamination through soil layer and rock layer. By the numerical simulation on transport principle of major contamination ion(Ca~(2+)和Mg~(2+)) in Fuxin southern coal mine, the paper obtained the variation curve of concentration and the head pressure curve of underground water at the particular cross section. The results are useful and helpful for the disposal of polluted water. |
