Multi-Parameter Nonlinear Acoustic Emission Precursors of Failure in Coal with Different Burst Tendencies

Acoustic emission (AE) monitoring is widely used to characterize coal failure, but specimens with different burst tendencies cannot be distinguished reliably using a single count, energy, b-value, or fractal indicator. This study reanalyzed archived Vallen AE data from uniaxial-c...
