Implications for rock instability precursors and principal stress direction from rock acoustic experiments
TL;DR: In this paper, the authors investigated the qualitative relationship between rock instability precursors and principal stress direction through wave velocity in rock acoustic emission (AE) experiments and showed that wave velocity variation exhibits obvious anisotropic characteristics in 0% −20% and 60% −90% of peak strength due to the differences of stress-induced microcrack types.
