some 35 years after the original Lerchs-Grossman algorithm (1965). It took 20 years from the formulation of the LG algorithm for it to be incorporated in the first commercially available software (Whittle Three-D), with another 10 years before it became a mainstream approach to open pit optimization.

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.

Definition of the optimum open pit, whether an intermediate phase or final design, will be sensitive to many factors. The most basic will include geological and mining constraints, mining and processing costs, pit slopes and product prices. The application of the three dimensional Lerchs-Grossmann pit optimization procedure to this task is described for a range...

Abstract. One of the most important design factors in open-pit mining is determination of the optimal pit. Pits may be redesigned many times during the life of a mine in response to changes in design parameters as more information is obtained and to changes in the values of technical and economic parameters.

The techniques are an attempt to solve limitations of the Lerch Grossman algorithm that became an industry standard for defining ultimate pits and nested push backs. Currently the Lerch Grossman (designed in 1964-1965) algorithm is used to define economic viability of a pit by outlining the ultimate pit using economic and mining parameters.

In this thesis, we study the open-pit design problem, the open-pit mining scheduling problem, and the open-pit design problem with geological and price uncertainty. These problems give rise to (mixed) discrete optimization models that in real-life settings are large scale and computationally challenging.
