摘　　要：在分析德尔尼矿区试验剖面的基础上,论述了综合物探方法在调查外围隐伏矿体中的应用。激电扫面可快捷有效圈定异常范围,瞬变电磁法、可控源音频大地电磁法可快速判定异常体的位置、深度、倾向。多种方法相互佐证,结合地质资料排除干扰,可有效降低多解性,为下一步地质重点工程提供资料依据。实践表明,研究成果与钻孔资料、已知矿体基本吻合,在此基础上对德尔尼东、西两区提出了后期工作的重点目标靶区,表明在本区利用这些物探方法来寻找以低阻异常为特征的铜钴矿体是行之有效的。This paper discusses of the integrated geophysical survey method used in peripheral concealed ore bodies.The IP sweep is efficient,delineating abnormal.Transient electromagnetic and controlled source method can be quickly determine the position,depth,and tendency of anomalous bodies.Integrated geophysical combining with geological data can solve the problem of multi-interpretations in geophysics,providing the useful area for next geological work.Practice shows that the research achievement is in good agreement to borehole data and known ore bodies.Based on the analysis of the experiment,the authors give some target region in the east and west sides of DE’ERNI,indicating that using these geophysical exploration methods in low impedance to search for abnormal copper cobalt ore is effective.
