This study aims to reveal the evolution of energy, cracks, force chain, and ultimate failure modes cemented gangue backfill materials subjected static-dynamic combined loads, as well reinforcement mechanisms pre-tightening bolts on mechanical performance progressive damage. The particle flow models with various fractal dimensions (D) size distribution were established, irreversible damage accumulation during dynamic loading was achieved through a nonlinear parallel-bonded stress corrosion model. simulation results show that, compared uniaxial compression, energy release lag at peak strength is eliminated under loading, brittle feature becomes more pronounced. filling effect fine aggregates optimizes uniformity internal distribution, parallel bond strain increasing by 9.60%, 8.42%, 14.81% D increases from 2.1 2.85. At initial instantaneous increase in axial reaches crack initiation stress, significantly number tensile cracks. As pre-static load increases, model sample higher environment leading remarkable chain breakage observed strength. Shear failure, including oblique shear tensile-shear mixed primary mode loading. additional constraints provided stored particles contacts reduce strength, constraining exhibiting pronounced preload increases. For anchored samples, end pallets point for which extend along edge concentration area, while cracks initiating ends propagate toward area.
