摘要
采矿对地下水造成的影响主要是水位下降,以北方某金矿为例,探讨在《环境影响评价技术导则—地下水环境》指导下如何进行采矿区地下水环境影响评价工作。根据导则确定本次评价的等级为二级。通过水文地质条件合理概化,选用合理的公式,用解析法辅以数值法预测倾斜承压含水层中采矿对地下水的影响。结果表明,本区采矿活动对浅层地下水造成的影响不大,结果合理,可以为类似矿山的地下水环境影响评价提供参考。
The main impact of mining on groundwater is water level decline. In order to discuss impact assess- ment on mine area under Technical Guidelines for Environmental Impact Assessment groundwater environmental, this paper takes a gold mine in Northern China as an example. According to the guideline, the level of this assess ment is grade two. Through reasonable generalization of the hydrogeological condition and selection of formula, the impact of this mining activity on groundwater in inclined water-bearing layer is predicted by analytical and numerical methods. The result shows that the mining activities have little effect on shallow groundwater, and the result is reasonable, which can be a reference to other similar mines.
