The problem of modeling a non-stationary 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 ore objects, and measurements are carried out inside it. Based on the numerical modeling data, their influence on the electromotive forces (emf) measured using the transient process method is 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 daylight surface. The magnitude of the electromotive force (emf) anomaly and its duration in time correlate with the number of conductive objects.
N. V. Shtabel (2025) studied this question.
