This paper overviews the simultaneous stochastic optimisation of mining complexes or
mineral value chains where raw materials mined from mineral deposits in an area are …

Existing methods of pushback (phase) design are reviewed in the context of “gap” problems,
a term used to describe inconsistent sizes between successive pushbacks. Such gap …

An economic argument is presented for the incorporation of quantitative modelling of the
uncertainty of grade, tonnage and geology into open-pit design and planning. Two new …

The annual production scheduling of open pit mines determines an optimal sequence for
annually extracting the mineralized material from the ground. The objective of the …

Open pit mine design and production scheduling deals with the quest for the most profitable
mining sequence over the life of a mine. The dynamics of mining ore and waste and the …

Conventional approaches to optimising open pit mine design and production scheduling are
based on a single estimated orebody model, which does not account for geological …

This article presents a novel stochastic optimization model that simultaneously optimizes the
short-term extraction sequence, shovel relocation, scheduling of a heterogeneous hauling …

Optimization of long-term production scheduling is important for managing the substantial
cash flows inherent in open pit mining ventures. In terms of ore grade, tons and quality …

Meeting production targets in terms of ore quantity and quality is critical for a successful
mining operation. In-situ grade variability and uncertainty about the spatial distribution of ore …

Life of mine (LOM) production scheduling is a critically important part of open pit mining
ventures and deals with the efficient management of cash flows in the order of hundreds of …
