摘要
文章在对广西某铅锌矿矿区水文地质条件分析的基础上,采用连通试验对地下水动态特征及其影响因素进行分析评价。实验结果表明,矿山区域地下水流经地下巷道携带大量重金属离子由废旧矿洞口排出地表,地表水流经地表废旧矿渣堆场携带大量污染物和矿洞水汇成溪沟,然后以地表径流方式污染长屯的土壤和水系,最终由长屯南伏流入口汇入洞零水库。尾矿库区域地下水通过地下岩溶管道和溶蚀裂隙向长屯洼地径流,经长屯南伏流入口,汇入洞零水库。
Based on the analysis of hydrogeological conditions of a lead-zinc mine in Guangxi,this paper analyzed and evaluated the dynamic features of ground water and its influencing factors by applying interconnection test.The test results showed that the ground water carried a large amount of heavy metal ions and emitted to surface from waste boreholes,and the surface water flew through the surface of waste slag carrying large amounts of pollutants and formed gullies with borehole water,and then contaminated the soil and water system of Changtun through runoff,and finally converged into Dongling Reservoir through the influx of south Changtun subterranean stream.The ground water of the regional tailings pond area flew to Changtun depression through the underground karst pipes and grykes,and finally converged into Dongling Reservoir through the influx of south Changtun subterranean stream.
