磷矿山开采对黄柏河东支的影响研究

Influence of phosphate mine mining on the east branch of Huangbai river

从黄柏河东支流域磷矿山绿色开发要求出发,基于地表水环境系统和矿业开采的耦合影响作用,开展了磷矿山开采对黄柏河东支的水环境的影响研究。通过定量和定性分析,在磷矿山开采过程中对黄柏河东支的各种影响因素中,矿井涌水(占比为43.19%)、尾渣淋溶水(占比为15.51%)、矿废石淋溶水(占比为14.64%)和生产废水(占比为10.84%)为磷矿山开采对黄柏河东支水环境的主要影响因素,尤其是矿井涌水携带的总污染物量大,影响占比接近50%。该研究影响分析为黄柏河东支水环境的治理提供有力指引支撑。

Based on the requirements of the phosphate mine green development in the east branch of Huangbai river basin and the coupling effect of surface water environment system and mining,the impact of phosphate mine mining on the water environment of the east branch of Huangbai river was studied.Base on the quantitative and qualitative analysis,it is found that the influence of phosphate mine mining on the east branch of Huangbai river is mainly reflected in mine gushing water(43.19%),leached water of dressing tailings(15.51%),leached water of surface rock storage yard(14.64%),production waste water(10.84%).Furthermore,the mine gushing water,in phosphate mining has a great influence(nearly 50%)on the water environment of the east branch of Huangbai river.The impact analysis provides a strong guidance and support for water environment management in the east branch of Huangbai river.
