  Pit optimisation using solid modelling and the Lerchs Grossman algorithm
 
 
Title: Pit optimisation using solid modelling and the Lerchs Grossman algorithm
Author: Stuart, N.J.
Appeared in: International journal of mining, reclamation and environment
Paging: Volume 6 (1992) nr. 1 pages 19-29
Year: 1992
Contents: 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 of a convex polyhedron using a conical slope criterion is given. If the shapes, values and relationships between, these overburdens are determined then one can obtain all the information required by the Lerchs Grossman algorithm for optimisation.
