Abstract
The stability of the slopes of an open-pit copper mine was analysed in two dimensions with the use of a finite-difference code. The properti es of the rock material were determined in the laboratory and subseque ntly modified to approximate those of the in-situ rock mass of the ope n-pit slopes. Geotechnical mapping was undertaken to determine the cri tical orientation of structural discontinuities. The results of the nu merical modelling work indicated that an open-pit 148 m in depth would be stable with overall slope angles of 60-degrees.
