We recently held a webinar on the new Minex Pit Optimizer, presented by myself, GEOVIA Senior Mining Consultant at Dassault Systèmes, Ranajit Das.
During the webinar I talked about the below points in detail:
- What is Optimization?
- Different methods of Optimization
- The Minex Optimizer
- The new Optimizer
- Further possibilities with Optimization
Pit Optimization is a tested and widely accepted ranking method. Developed in 1965 by Lerchs and Grossman working for IBM, pit optimization was commercialized by Jeff Whittle as Whittle 3D and Whittle 4D, and was introduced into Minex in the early 1990s.
- Which part is economic?
- How should we mine it?
- How does it compare with other company projects?
- What is the risk if coal prices fall or rise?
