Declining trends in average ore grades, increasing mining costs and environmental considerations will ensure that this situation will remain in the foreseeable future. The operation and management of a large open pit mine having a life of several (5–50) years is an enormous and complex task.
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.
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

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.
Mathematical optimization models and case studies for longterm open pit mine planning will be presented. Blending problem formulations are setup and solved in Excel Solver. The course complements theory with comprehensive instructions and handson experience completing a project using GEOVIA Whittle strategic mine planning software.
