Abstract
A three-dimensional dynamic programing method is presented for determining the optimal open pit limit. The method given is based on the block concept and is an extension of the two-dimensional lerchs-grossman approach. The three-dimensional technique presented herein is fast and simple and may be used for an initial open pit evaluation when only limited data are available or as a more refined model when the entire deposit is well delineated. The method is illustrated by simple numerical examples and is also presented in algorithmic form. A computer program was written in Fortran IV which implements the three-dimensional algorithm and some computational aspects are discussed.
