摘　　要：岩溶山区地下河系统发育,且水文地质条件复杂,含水层渗透性强、防污性能差,一旦发生污染,污染源精准识别和污染通道的精准查证的难度大,本文以坪桥地下河系统为例,通过环境水文地质调查、水地球化学、物探、钻探、测井、水质分析等技术的优化组合应用,精准识别该地下河系统的主要污染源为工业废渣处置场,并精准查证了工业废渣处置场2#坝东部抽排竖井—CK8—J02监测井—CK6、CK11钻孔一线是该系统的污染通道之一,为该地下河系统的污染修复治理提供了技术依据,构建了岩溶山区地下水污染源精准识别和污染通道精准查证的勘查技术体系,该技术体系可复制、可推广应用于其他同类型岩溶地区。The underground river system in karst mountain area is developed,and the hydro-geological conditions are complex,the permeability of aquifer is strong,the anti-pollution performance is poor,once the pollution occurs,it is difficult to accurately identify the pollution source and accurately verify the pollution channel,taking Pingqiao underground river system as an example,this paper presents the application of environmental hydro-geological survey,water geochemistry,geophysical prospecting,drlling,logging,water quality analysis,etc.,accurately identify the main source of pollution in the underground river system as the Industrial Waste Disposal Site,it is accurately verified that the CK8-J02 monitoring well-CK6,CK11 borehole line is one of the pollution channels of the system,it provides the technical basis for the remediation and treatment of the pollution in the underground river system,and constructs the exploration technical system for the accurate identification of the groundwater pollution source and the accurate verification of the pollution passage in the karst mountain area,the technical system can be replicated and applied to other karst areas of the same type.
