高频大地电磁测深法与双频激电法在水文地质调查中的应用

以在新疆某金矿展开的水文地质调查为例,研究和分析高频大地电磁测深法与双频激电法相结合的方法在受人文干扰较大的矿区内找水的可行性与应用效果。研究和分析结果表明:在人文干扰较大的区域使用双频激电法对高频大地电磁测深法进行补充,可避免因人文干扰对高频大地电磁测深法观测影响而错误推断断层位置,能显著提高断层位置推断的精度;两种方法相结合,能有效地解决在受人文干扰较大的矿区内找水的问题。

The application of high frequency MT sounding method and dual frequency IP method to hydrogeological survey

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 interfer?ence effectively.
