Abstract :
New methods of cracking process stages determining by means of electromagnetic emission (EME) signal pulse flow intensity estimation were developed. These methods allow to increase the reliability of solids cracking forecasting by means of EME registering. On the basis of recording the electromagnetic radiation signals, the effect of origination of periodical low-frequency signals at the stage, preceding the separation of rock sample continuity is revealed.
