Influence of Induction Masses of Conductive Objects according to Data of Numerical 3D Modeling of a Signal in the Transient Processes Method

Abstract—The problem of modeling a nonstationary electric field in a spatially inhomogeneous medium with three closely located conductive ore objects is considered for an installation in which the generator loop covers the entire area with the ore objects and measurements are carried out inside it. Based on numerical modeling data, their influence on the emf measured using the transient processes method was studied. Analysis of the received signals showed that the significant influence of conductive objects is local in nature with time and manifests itself in the zone of projection of objects onto the Earth’s exposed surface. The magnitude of the emf anomaly and its duration correlates with the number of conducting objects.
