Abstract

This paper describes a method for optimising the layout of a decline in an underground mine. It models a decline as a mathematical network connecting the access points at each level of the proposed mine to the surface portal. A feasible decline is one satisfying all operational constraints such as gradient and turning radius requirements. The task is to find the decline that minimises a given cost objective. Typically, the cost objective will be some combination of development and operational costs representing a project cost or a life-of-mine cost. The procedure to find the optimal decline has been automated and the paper describes the current capability of Decline Optimisation Tool (DOT) s..
