Abstract
The principles of the physical mesomechanics paradigm are a constructive means for studying a nonstationary geological medium. In situ experiments in real rock masses subjected to a strong anthropogenic effect provide constraints on the behavior of geophysical fields in the geological medium. The active geophysical monitoring of electromagnetic or seismic fields plays an important role in the study of such dynamic systems. We propose a new parameter of the interval intensity of disintegration zones determined from active electromagnetic monitoring data in order to quantitatively classify the rock mass state in terms of three gradations, stable, unstable, and intermediate. The temporal variation of this parameter is studied. Seismological ore prospecting data are compared with the electromagnetic monitoring results.
