suboptimal open pit mining designs in terms of maximizing net present value. Methods such as the Lerchs– Grossman algorithm, network flow techniques, the fundamental tree algorithm, and Seymour's parameterized pit algorithm are examined to see how they can be used to produce pushback designs and how they address gap issues.

Abstract: Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price.
