GEOVIA Whittle Strategic Mine Planning Dassault Systèmes®

Because pit optimization alone is not enough to unlock the full economic potential of your operation, Whittle provides mine optimization, which enables significant increases in project value over and above pit optimization With its 64bit platform, Whittle handles large data sets designed to optimize In the case of conventional openpit operations, the optimization of the trench, which aims to design a pit allowing both a very good recovery of the deposit and a cost of the extracted metal as low as possible, is one of the elements essential elements of the feasibility studyOptimization of Open Pit Mining under Surpac and Whittle In Whittle [1, 25, 7, 9, 1013], a con struction of possible open pits is made based on the Lerches and Grossman algorithm The Lerches and Grossman algorithm is a ALGORITHM OF OPTIMIZATION THE OPEN PITS USING THE
