As open pit mining of a mineral deposit deepens, the cost of extraction may increase up to a threshold where transitioning to mining through underground methods is more profitable. This paper provides an approach to determine an optimal depth at which a mine should transition from open pit to underground mining, based on managing technical risk.

A mining process or a sequence of processes, such as open pit design and production scheduling is conceptualised here as a transfer function. The specification of a transfer function depends on the problem under consideration. For example, in pit optimisation, Whittle 40is a specific transfer function used in the mining industry.
