Abstract: The surface-hole transient electromagnetic method (SHTEM) is used to explore deep mineral resources by which field source is excited on surface and transient responses are observed through receiving coil in borehole. The mutual inductance coefficient and induced voltage between equivalent eddy current ring and Rx are calculated based on the principle of equivalent eddy current ring method. By establishing a mathematic model of multiple thin-plate conductors, the response superimposed field is calculated and simulated under the condition that there are combinations of multiple thin conductive plates underground to study the surface-hole transient electromagnetic anomaly responses of multiple conductors and analyze their characteristics and rules. It is considered that multiple combinations of thin plate orebodies can be distinguished through SHTEM when they are close to the borehole.
