Abstract

CSAMT always use MT to calculate the Cagniard resistivity which is the ratio of electric field component and magnetic field component. CSAMT field source is known and the electric field component and the magnetic field component have a certain relationship with the underground resistivity. Therefore the single-component date including magnetic field component or electric field component can be used to extract the apparent resistivity. In order to improve the influence of noise to data interpretation, the paper put forward that the single-component of CSAMT is used to calculate the apparent resistivity through analyzing the data quality of magnetic field component and electric field component. The generalized inverse matrix inversion method is used and the layer number equals to time channel. The method overcomes the problem that the layer number is low, and the fitting inversion of the apparent resistivity curve in the whole field is realized. The detection of the result of seeper mine-out area in Datong show that the single-component detection and interpretation method is effective.
