| 摘 要： | 矿山开采对地下水的影响主要是水位下降。以紫金山金铜矿为例,通过对矿山开采金铜矿以来多年间的地下水环境质量进行分析评价,查明地下水的变化趋势。采用承压转无压完整井裘布依公式计算等方法,得出了井下开采不同中段的涌水量及疏干影响半径的计算成果;结合水源水质分析.预测了矿山开采对于地下水水质影响的变化趋势。结果表明:矿区的开采活动对于地下水水位降幅影响较大,对地下水水质影响较小。

| Abstract: | The main impact of mining on groundwater is water level decline. In order to analysis the quality of groundwater environment and identify the change trends of groundwater, Zijinshan Au—Cu deposit was taken as example. The water inlfow and the dewatering inlfuence radius were calculated by Dupuit formula, and the change trend of mining groundwater quality was predicted combined with water quality analysis.The results show that the mining activities have a signiifcant effect on groundwater level drawdown while little effect on groundwater quality. |
