Mechanical Behaviors and AE Characteristics of Brittle Coal Specimens with Different Fissure Angles
Uniaxial compression tests were performed on coal specimens with five fissure angles to study the mechanical behaviors and acoustic emission (AE) characteristics of fractured coals. AE and video monitoring techniques were used to examine crack propagation in the fractured specimens. The stress–strai...
