摘要
Advanced field experiment in electromagnetic exploration is of importance for performing geological projects and evaluating data interpretation.First,the measuring time is computed by geoelectric parameters,then the transmitting loop side and current could be determined according to the noise electric level.After the test of wave form,the measuring time will be confirmed through the geological effect experiment beside drill holes.Nevertheless,the signal-to-noise ratio,the coincidence and the stability should meet the requirements of prospecting accuracy.
