The main objective of this paper is to enhance the understanding of the underlying mechanisms of bulk solid flow through a constrained passage based on design parameters. In this study, ore pass design parameters, information on size distribution of rock fragments in ore/waste dumps are used for a computer simulation. One of the important parameters in ore pass design is the angle of the ore pass itself. Various inclined ore pass models were created in Working Model 2D. Rock flows were simulated utilizing these models to investigate the relationship between the angle of ore pass inclination and the impact loads on the gate and ore pass walls.
