which was unusable in practice until a practical optimization program called Whittle ThreeD was developed by Jeff Whittle of Whittle Programming Pty Ltd in the mid1980s. Two methods to the solution of open pit optimization were detailed by Lerchs and Grossmann, being a Graph Theory algorithm, which is a heuristic approach, and a

Determining an optimum long term production schedule is an important part of the planning process of any open pit mine; however, the associated optimization problem is demanding and hard to deal with, as it involves large datasets and multiple hard and soft constraints which makes it a large combinatorial optimization problem. In this paper a procedure has been proposed to apply a relatively ...

Abstract. This paper demonstrates the application of Surpac and Whittle in open pit optimisation and design. Exploration data on the Tabakoto deposit of AngloGold Ashanti Sadiola Mine (AASM) has established 13 652 661 tonnes of gold resource with an average grade of g/t that could be mined using open pit method.

an openpit productionscheduling model, also called the openpit blocksequencing (OPBS) problem. At the strategic level, the ultimate pit limit (UPL) problem, based on the seminal work of Lerchs and Grossmann (1965), provides a solution for the ultimate pit limit contours of a deposit with the objective of maximizing total profit.

Traditionally, the optimization of open pit mine design consists primarily of defining the "ultimate pit limits" which, in their turn, define what will eventually be removed from the ground, and dividing ... approach used by LerchsGrossman implementation of Whittle [8]. A series of ...

Whittle comprises a number of modules that focus primarily on pit optimization and strategic mine scheduling. For the Study, only the modules associated with pit optimization were utilized – the Core and MultiElement modules. Whittle determines the optimal shape for an open pit in three dimensions through implementation of the

The design of pushbacks in an open pit mine has a significant impact on the mine''s profitability. Automatic generation of practical pushbacks is a highly ... modification, which is adopted by the Whittle tool. A standard optimizationbased method is the parametric maximum flow method (Hochbaum and Chen, 2000). Another alternative is

Jun 03, 2015· One of the first steps in open pit mine design is the completion of a pit optimization analysis. Pit optimisation is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters generally include the metal prices, process recoveries, and operating costs.
