Homogeneity-dependent fracture behavior and instability mechanism of composite coal-rock: Insights from three-point bending tests
To investigate the instability mechanisms of heterogeneous geological structures in goaf area roofs, three-point bending tests (TPBT) and numerical simulations are performed on composite coal-rock (CCR). Acoustic emission (AE) monitoring is employed to analyze key parameters, establishing a multi-pa...
