which was unusable in practice until a practical optimization program called Whittle Three-D was developed by Jeff Whittle of Whittle Programming Pty Ltd in the mid-1980s. 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

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 Multi-Element modules. Whittle determines the optimal shape for an open pit in three dimensions through implementation of the

Ultra-Fast Pit Optimizer. GeoMine's FlowPit is an ultra-fast open pit optimization module. FlowPit implements the industry standard Lerchs-Grossmann's 3D pit optimization algorithm, but with a novel implementation. FlowPit's highly efficient and scalable implementation achieves a superior magnitude speed-up in comparison to competitors.

Abstract Miners harvest minerals from ore-bodies in the ground by a variety of specialised mining methods, with most falling into the categories of open-pit and underground. Some ore-bodies are harvested by a combination of open-pit and underground methods. In these cases there is often material that could be mined by either method, and an economic choice has to be made.

The moment in which the optimization is carried out is very important to maximize the value, because of the impact of the discount rate on it. Regarding maximization of the NPV, some of the key decisions about the exploitation of an open pit deposit are the starting point and the orientation of the mining sequence.

Whittle is a mine planning tool to optimize an open pit mine in order to maximize the output, i.e., Ore and NPV. Whittle software works on the geological model finally freeze in the Surpac Software. In order to carry out pit optimization, the economic pit limits were determined by using the Whittle (V. 4.7) software.

Abstract: The delineation of mining boundary is the basis of open-pit mining design,the results of boundary optimization directly restrict the overall development benefits of the mine.Due to a series of non-linear dynamic problems such as complex and changeable geological rock mass,disordered grade distribution and changeable economic parameters are existed in the mining process of open ...
