Abstract

Surface-borehole TEM method has achieved good results in exploration in Canada and Australia. Due to the lack of complete technology from equipment to data processing and interpretation, the method has not been widely used in China. The authors developed the surface-borehole TEM instrument and, at the same time, systematically studied the determination of the three component coordinates of the surface-borehole TEM, the measurement of the deviation of the probe angle, the correction of the three components, and the analysis and calculation of the orientation and distance of the target body, which achieved good application results in actual measurement.

Key words： surface-borehole TEM measuring the deviation of the angle of the probe three component correction target body location
