摘　　要：西南地区岩溶分布广泛,较多尾矿库修建于大型岩溶洼地或谷地。而早期岩溶地区修建的尾矿库防渗等级不高,存在污染物外溢问题,污染物通过岩溶管道汇入地下水系统,造成地下水污染,对生态环境造成不利影响。以西南某尾矿库为例,通过地质及水文地质现场调研分析得到研究区域岩溶发育主要受水文及水文地质、地形地貌、岩性、地质构造综合影响。通过水文洪水分析得到岩溶管道洪水与地表水的相互转化较为迅速,以及岩溶管道洪水来水快、退水慢的特点。最后结合地质、水文研究成果以及现有污水处理能力,形成了“末端调蓄处理+源头雨污分流”的综合治理方案。Karst is widely distributed in the southwestern region,and many tailings ponds are built in large karst depressions or valleys.However,the anti-seepage level of tailings ponds built in early karst areas was not high,and there was a problem of pollutant overflow.Pollutants flowed into the groundwater system through karst pipelines,causing groundwater pollution and adverse effects on the ecological environment.Taking a tailings pond in Southwest China as an example,through geological and hydrogeological field research and analysis,it was found that the karst development in the study area is mainly influenced by hydrology and hydrogeology,topography and geomorphology,lithology,and geological structure.Through hydrological flood analysis,it is found that the mutual transformation between karst pipeline floods and surface water is relatively rapid,and karst pipeline floods have the characteristics of fast inflow and slow outflow.Finally,combining geological and hydrological research results with existing sewage treatment capabilities,a comprehensive treatment plan of"end of pipe regulation and storage treatment+source rainwater and sewage diversion"was formed.
