ABSTRACT The concept of pit optimisation and the Lerchs Grossman algorithm are reviewed. The implementation of the algorithm with respect to block models is considered. The concept is extended to solid models. Ore bodies are conceived to be divided into units that have significance to the mining engineer, can be geometrically described (e.g. as irregular polyhedra) and values given. A geometric method for determining the overburden must be devised -here an algorithm for finding the overburden… CONTINUE READING
