This paper briefly describes the principle and characteristics of the dual frequency induced polarization method on the basis of the application in typical overburden area (savanna area coverage) of Western Australia, and discusses such aspects as to how to solve the problems met in work plan design, array selection, selection of working frequency, and conductivity improvement, and how to overcome inductively coupled problems under the special geological landscape condition. What is more, the authors give the solutions of these problems and make a summary of some work principles of universal value. In conclusion, the dual frequency induced polarization method has good application effect in the special environment of a gold mine in Australia, the delineation of the IP anomalies is consistent with the expectation of geologists, and engineering verification is necessary for further work. It is held that the dual-frequency IP method in the process of design and field construction in overseas mineral exploration work should be based on the comprehensive analysis of the influencing factors in various aspects as well as scientific decision-making, and effective measures should be adopted to eliminate the possible factors affecting the accuracy of the measurement data. Only in this way can we enjoy the full play of the technical advantages of the dua-frequency IP method and obtain satisfactory results.
