Abstract

Ore passes are vertical or steeply inclined openings in a rock mass through which ore and waste are transported from one mining level to another using the driving force of gravity and where they may also be stored. An ore pass is, in effect, a silo excavated in a rock formation. Production in most deep underground mines depends on the safe and continuous operation of the ore pass system. Since ore passes are dependent upon only gravity for moving the materials, they require less energy. However, despite the existence of standard design guidelines, hang ups, wall failures and other ore pass problems still occur frequently in underground mines. This paper describes the development and application of a rigid cluster and a superquadric based discrete element computer code to predict material flow in ore passes and improve safety and performance. The discrete element method (DEM) model parameters include the size distribution, friction, and shape of ore particles and ore pass geometry.
