Numerical Investigation of Rock–Backfill Composite Fracture Evolution Laws Under Deep Mining and Filling Stress Paths

Fracture evolution of rock–backfill composites (RBCs) under complex loading–unloading and dynamic disturbances is critical for stope stability in deep backfill mining. Using PFC3D, this study constructs numerical models of RBCs to investigate this process, considering burial depths (500, 1000, 1500, 2000 m), interface...
