为了查清云南金平长安金矿区的控矿断裂F6深部的延伸情况，开展了2条EH－4剖面试验测量。通过对反演电阻率断面图低阻体的圈定，较好揭示了控矿断裂F6的空间分布形态，并结合地质上的认识，提出了矿体深部存在第二找矿空间的可能，为长安金矿床下一步的深部及边部找矿提供了参考依据。传统上寻找金矿床主要是以化探手段为主，但对于长安金矿床这种严格受断裂控矿、第四系覆盖层较厚、断层地表特征又不明显的金矿床，通过物探手段来查清断裂的空间分布形态对于指导找矿具有重要的意义。

Two profile measurements of EH-4 have been made in mining areas to find out the stretch in deep F6 fracture that is ore-controlling in Chang'an Gold Mine in Jinping County of Yunnan Province.The delineation of low re-sistivity in the resistivity section diagram of inversion reveals the spatial distribution of the ore-controlling F6 fracture. Based on the geological understanding, it is believed that there is a second prospecting space deep in the orebody, which lays the foundation for next step exploration in deep and surrounding areas of Chang'an Gold Deposit.The explo-ration of gold conventionally depends on geochemical means in the past.However,the Chang'an Gold Mine is strictly controlled by fracture,and the feature of fracture is not obvious because of the quaternary is too thick in the area.So the utilization of geophysical methods to investigate the spatial distribution pattern of the fracture will be instructive for the exploration of gold.
