When GEOVIA Whittle was initially released in 1984, it provided a new Lerchs-Grossmann (LG) algorithm for open pit shell optimization to replace the existing floating cone method. While it took a number of years for the mining industry to become accustomed to LG, it is now the industry standard for pit optimization.
Strategic Mine planning tools often appear as black boxes – on one hand, we have multiple input parameters that need to be gathered by the strategic mine planner without fully realizing its significance in the optimization process; and on the other hand, an optimization result showing great improvement in the value of the mine without full understanding of how the solution was found.
Likewise, with the Advanced Simultaneous Optimization module available in GEOVIA Whittle since the 4.7 release, it can be difficult to unlock the full value of a mine without the understanding of the technologies and methodologies used.
We have published a White Paper that describes the technical foundation of the Advanced Simultaneous Optimization (Advanced SIMO) module in Whittle. The white paper provides a description of the technical foundation for:
- Block parcel aggregation;
- The formulation of the mine planning problem into solvable linear systems;
- An iterative methodology to optimise the mining plan and stockpile grades; and
- The benefit of simultaneous optimization over sequential and traditional optimization methods
If you are interested in pushing the limit of your mining operations and would like to learn how Simultaneous Optimization works, we encourage you to download the paper here.
