Identification of acoustic emission precursors for strainbursts in dry and saturated sandstone under true triaxial transient unloading
Groundwater is a key factor influencing rockburst in underground engineering. Identifying how water alters precursory signals is essential for reliable prediction and mitigation. Using a self-developed true triaxial rockburst system integrated with high-speed camera (HSC) and acoustic emission (AE) monitoring, we inves...
