Rock hang-ups are a problem in ore pass operations. Rock flows through an ore pass by gravity but hang-ups can occur due to bridging of larger rock particles. Hang-ups also occur if cohesive fine rock particles are present. The result is a production stoppage, where secondary blasting or other relief is required where human safety is at risk. Existing ore pass design criteria rules-of-thumb using current particle flow equations are reviewed and a comparison of two computer modeling programs, Working Model (WM 2-D) and PFC2d, to simulate rock flow are investigated.
