Particle-Scale Insights into Extraction Zone Development During Block Caving: Experimental Validation and PFC3D Simulation of Gradation-Dependent Flow Characteristics
To investigate the evolution trend of the extraction zone above the drawbell in block caving, an experimental apparatus incorporating the drawbell structure was designed. Ore drawing experiments were conducted using materials with varying particle size gradations. The results demonstrate that the ex...
