Short-term planning of the ore extraction process in open-pit mines is a complex undertaking that necessitates the identification of the best spatio-temporal machinery affectation.

SYNOPSIS Long-term production scheduling is a major step in open pit mine planning and design. It aims to maximize the net present value (NPV) of the cash flows from a mining project while satisfying all the operational constraints, such as grade blending, ore production, mining capacity, and pit slope during each scheduling period.

An example of a strategic change to an open pit mine plan as metal prices rise and therefore allow production access to deeper ore. This is Part 2 of the insight focusing on the mining strategy selection by using evaluations as a method. Part 1: Early phase concept development in mining operations focuses on the early phase of mine …
