DEVELOPMENT AND APPLICATION OF SYNCHRONOUS SCANNING FREQUENCY ELECTROMAGNETIC METHOD

This paper describes the technical principle and the field source mechanism of a high frequency magnetotelluric method used for solving some geolgical problems, such as subsurface karst,ancient mined out space,and distributions of accumulated water,subsided pillar,fire area and determination of water supply well,as well as geothermal,engineering and enviromental protection problems. Combined with specific application examples,the application of this method in pre mining exploration, flood protection and water supply is also discussed. The curve resonance characteristics in different areas and different geological and hydrogeological conditions are analysed, and basic interpretation method of the synchronous scanning frequency electromagnetometry is proposed as well.
