Abstract

Optimal open-pit design is, essentially, a computer-based implementation of an algorithm that is applied to a three-dimensional block model of an orebody. The first computer algorithm, published in 1965 by Lerchs and Grossmann, has spawned one of the most active areas of operational research in the minerals industry. Although this algorithm was, for at least 25 years, the only demonstrably rigorous method of arriving at the optimal shape of an open-pit, it is still not widely used in the industry. It is, however, almost universally accepted as the benchmark against which all other algorithms are judged.
