Abstract
Anisotropy caused by bedding structures has a great effect on tensile properties and fracture behaviours of coal. Acoustic emission (AE) monitoring is a powerful tool in understanding the anisotropy of inherent failure mechanisms. Brazilian disc tests in a split Hopkinson pressure bar (SHPB) system were conducted on coal specimens with bedding orientations β (0°, 30°, 45°, 60°, and 90°) to investigate the damage evolution and AE characteristics....
