Possibility of total fracturing forecasting of loaded rock samples on the base of ultrasonic emission analysis
Rudajev, Vladimír ; Lokajíček, Tomáš ; Vilhelm, Jan
The ultrasonic emission, generated by rock samples loading, was subjected to autocorrelation analysis. The increase of autocorrelation coefficients and the tendency to their linear decrease is evidence of redistribution of stress in the sample, which occurs after stronger ultrasonic events. The above-mentioned parameters have a precursory character.
