Study on the evolution law of acoustic emission time series characteristics of coal-rock assemblage under true triaxial conditions

IntroductionThis study aims to investigate the fractal characteristics of acoustic emission (AE) signals during coal-rock rupture and their predictive significance for impact dynamic hazards.MethodsTrue triaxial loading/unloading tests were conducted on five coal-rock composites with varying coal-th...
