摘　　要：利用高密度电法联合氡气测量对攀枝花白马铁矿Ⅰ#排土场及废石胶带输送工程拟建场址区内的隐伏断层进行探测,通过连接多条测线的异常来确定断层的走向及破碎带范围,综合利用两种物探方法的异常特征来推测断层的倾向和倾角。通过钻孔验证表明,高密度电法联合氡气测量的综合物探方法能对隐伏断层进行有效探测,同时这种组合方式也体现出了综合物探的技术优势。The high density resistivity method combined with radon survey is used to detect blind fault in the area of the proposed site in the project of No.1 refuse dump and barren rock transportation in Panzhihua Baima Iron Mine.The fault strike and the range of fracture zone is acquired by connecting anomaly belt on multiple lines,and predict the proneness and dip of fault by comprehensively analyzing the anomalous characters of two kinds of geophysical prospecting methods.Through the drilling test,there is an obvious fact that the comprehensive geophysical method with high density resistivity method and radon survey can detect blind fault effectively,and this combination mode also reflects the technical advantage of multi-geophysical prospecting.
