摘要
Electromagnetic method exploration faces strong and extensive electromagnetic interference.The anti-interference measures of different method and effect is introduced in this paper based on a large number of field test.The field test result show that it is suitable for TEM method to take the data collection method of high-power,multiple stack number,multiple repeated observation and noise monitoring.It is reasonable for CSAMT method to take large current,multiple notch filter,multiple repeated observation and noise monitoring data collection method.The multiple notch filter is suggested in AMT exploration,but AMT method is not suggested in strong noisy level area.
