METHOD FOR FORECASTING DESTRUCTION OF ROCK MASSIVE Russian patent published in 2004 - IPC

FIELD: mining industry. SUBSTANCE: method includes registration of signals of electromagnetic radiation and measurement of these signals durations. Method distinguishes itself for additional registration of beginnings of appearance of periodical low-frequency oscillations of electromagnetic radiation signals for determining beginning of massive integrity loss. On basis of increase of durations of periods of these oscillations with time and/or their amplitudes, process of massive integrity loss development is evaluated. In case of critical ratios defined by mathematical expressions on basis of starting and following periods of periodical low-frequency oscillations of given signals and/or respective amplitudes, critical state of massive integrity loss is evaluated, after which massive destruction occurs. EFFECT: increased precision of forecast of destruction of rock massive. 1 dwg
