Interconnections between the Polarization Current and the Electromagnetic Signal of Rock Samples under Loading

Article Preview

Abstract:

In the work the results of research emerging polarization current and of the electromagnetic signal with a change in the intense-deformed state of rock samples are presented. It is established that at stage of the intense-deformed state of rocks there is a correlation between emerging polarization current and the amplitude of the electromagnetic signal.
