Mechanical Behavior and Modeling of Polypropylene Fiber-Reinforced Cemented Tailings Interface with Granite Under Shear Loading: Effects of Roughness and Curing Time

Cemented paste backfill (CPB) is widely adopted in underground mines, where the shear resistance of the CPB–rock interface critically governs the integrity of backfill–rock systems. This study investigates the effects of polypropylene fiber reinforcement, surface roughness (Joint Roughness Coefficie...
