With the hydrogeological survey in a gold mine in Xinjiang as an example, the authors specifically studied and analyzed the feasibility and application effect of the technique that combines high frequency MT sounding method with dual frequency IP method. The results show that using the dual frequency IP method in the area affected by human interference can avoid the mistaken inference of the location of fault by high frequency MT sounding method, and enhance the precision of interpretation of the location of fault. The two methods make complements to each other and hence can solve the problem of water exploration in the mine affected by human interference effectively.
