Abstract
Many industries store and handle solid materials in bulk form. When the volume of the solids is large, industry invariably relies upon the gravity to induce the solids to flow out of storage, through channels and reactors. As an example production in most deep underground mines depends on the safe and continuous operation of ore pass systems. Their requirements to less energy (only gravity) have made them very popular not only in underground mines but also in open pit mines. This paper discusses the major findings of research on 2D Discrete Element Method (DEM) simulation of gravity flow of in ore passes. The study shows that ore shape, ore pass configuration and the existence of a Dogleg can significantly affect loads (static, dynamic) on the ore pass gate assembly and creation of hang-ups.
