Schedule Optimization

1. Consider your real production

In the early years of the project you will find a lot of concerns and the most value in terms of NPV. Knowing that, we decide to consider a 10-year surface to optimize the first 5 years. By an obvious assumption, as the surface used corresponds to a decade, it will contain the interval from the 1st to 5th period and represents a lot more mass. However, this simple input can restrict the space where the algorithm has to find a solution which could reduce the run time and help it to deliver better results respecting the set of constraints given.

Example:

    • Timeframe: Years (1).

      • Processing capacity: 10 Mt per year.

      • Total movement: 40 Mt per year.

      • Maximum of 4,500 processing hours per year.

      • Vertical rate of advance as 150m per year.

    • Minimum Mining (50 m) and Bottom(100 m) width.

    • Restrict Mining Surface: Surface002 from Exploratory Analysis.

    • Grade copper until 0.7%.

    • Stockpiling parameters on.
