河北平山县某矿区资源开采对地下水环境影响分析

Analysis of the environmental impact of resource exploitation on groundwater in a mining area in Pingshan County,Hebei Province

研究区位于河北平山县一带,资源开采过程中矿石废渣、扬尘、生产污水、矿井涌水等可能对地下水水位以及水质造成影响。基于此,本文结合区域地质背景以及矿区水文地质条件,分析了资源开采对矿区及周边地下水环境的影响。结果表明:采矿活动对矿区及周边地下水的水位影响较大,对更深的承压含水层水位影响较弱;对地下水的污染范围较小,且具有自西向东污染的趋势,可通过加强污染水源净化处理后再排泄等措施防治污染风险。

The research area is located in the area of Pingshan County,Hebei Province,and the possibility of the groundwater level and water quality may be affected by ore waste,dust,production sewage,mine surgewater,etc.during the exploitation of resources.Based on this,this paper analyzes the impact of resource exploitation on the mining area and the surrounding groundwater environment,combining regional geological background and hydrogeological conditions in mining areas.The results show that mining activities have a greater impact on the water level of the mining area and surrounding groundwater,and have a weak impact on the water level of the deeper pressurized aquifer,and the pollution range of groundwater is small,and has the tendency of pollution from west to east,which can prevent and control the pollution risk by strengthening the purification and disposal of polluted water sources.
