Diagnostics of destruction zone development in rock specimens during uniaxial compression based on the spectral characteristics of electromagnetic signals

Abstract

The results of the experimental investigations of variations in the spectral characteristics of electromagnetic signals (EMSs) generated by rock specimens from the Tashtagol iron-ore deposit and quartz-containing diabase in the process of uniaxial compression are presented. Patterns in the variations of EMS amplitude-frequency parameters in the process of destruction zone development and when approaching the ultimate strength of the specimens are revealed.
