通过频率域激电法在已知矿区实际观测结果，发现在第四系覆盖厚度较大的地区视频散率和激电相位参数存在严重的电磁耦合现象，电磁耦合的干扰湮没了激电效应异常。通过多项式法的视频散率校正和双频相位法的激电相位校正，分离出激电效应异常，且异常范围和形态特征与地下隐伏矿体对应的较好，取得了明显的应用效果。同时根据实际电磁耦合校正工作体会，指出频率域激电法中电磁耦合校正应注意的一些关键技术问题。

After observation of frequency domain IP applied in known ore district, it is discovered that there exists serious electromagnetic coupling for apparent frequency dispersivity and IP phase parameter in an area with thick Quaternary overburden, and the its disturbance submerged IP anomaly. After apparent frequency dispersivity correction by polynomial method and IP phase correction by dual-frequency phase method, IP anomaly was separated and its range and form fits well with the hidden ore body. Based on work experience in electromagnetic coupling correction, some key technical issues are given for the correction.
