摘要
在考虑矿山周围基本条件的基础上,选取13项地下水环境评价因子,对郑家坡铁矿第四系孔隙水和基岩水的环境质量现状进行了评价。化验结果显示,该2种水现状水质属极差。矿渣室内浸溶试验显示其浸溶液环境质量良好。通过渗水试验得出其土层入渗系数为0.0077m/d。矿渣堆存对地下水环境影响的综合评价结果为较小。
The assessment of the environmental actuality of quaternary pore water and bedrock water was made by selecting 13 environment assessment factors according to the basic conditions surrounding the mine. The chemical results show that the water quality of these two kinds of water is worst. The mine waste indoor lixiviation test indicates that the water quality of lixiviation hquor is good. The permeability coefficient of soil is 0. 007 7 m/d according to the permeability test. It is concluded that the mine waste disposal has a small impact on the groundwater environment.
