Abstract Inresponse to thesignificantincrease in waterinflowanddeteriorationof groundwaterenvironmentcaused by undergroundkarstchannelsinaSandonggoldmine，acomprehensiveexplorationofthecutainaxiswater-conductingchaelswas carried outbyusingtheinducedpolarizationdetectionmethodandshallowseismicmethod.Throughgeophysicaldatainterpretation anddrilingvification，treestrongwater-enrichednomalouszonesandonemediumpermeableanomalousznewereidentifid，nd thecorelationeteenfracturestructures（FF4，1O，tc.）andwaterconductinghaelsasevealed.Tesultssowatt shallowseismicmethodcanacuratelylocatethefracturesstem（verticalfracturedistaneof＼～30m），andtheinducdpolazation depthdetectionmethodcanefectivelydelieates thepermeablezone（burialdepthof40＼～2Om），whichprovidesareliablebasisfor the water sealing treatment in the mine area.
