METHOD OF MONITORING CHANGE IN FRACTURING IN ROCK MASS

摘要

FIELD: physics.SUBSTANCE: rock mass is scanned with probing signals in form of series of separate rectangular pulses. The position of the first zero of the function of the envelope curve of spectral power density of the received separate rectangular pulse is estimated. Changes in fracturing along a selected path are determined using said parameter.EFFECT: improved reliability and easy monitoring, possibility of real time monitoring.3 cl
