Scheduling Setup: Mining Rates

To access this screen:

  • Display the Optimization task bar and select Optimization >> Scheduler >> Maroma >> Settings >> Mining Rates.

Define mining rates for the Maroma scheduler.

Set the rate of mining for your schedule, either as a constant for all periods or as a custom rate for individual periods. A maximum rate must be specified, but a minimum rate is optional.

Rates can be defined either as Kilotons Per Day (Ktpd) or Million Tonnes Per Annum (Mtpa).

Rates can be optionally set according to loader capacity, cost and lifespan.

To set the rock mining rate for scheduling pushbacks:

  1. Define your scheduling periods.

  2. For each period, set (optionally) a Total Minimum rate.

  3. For each period, define a Total Maximum tonnage.

    Tip: Set multiple periods to the same value by selecting those rows in the table, entering a Ktpd or Mpta value and selecting Set Selected.

  4. If you want to let your loader capabilities define the mining rate, check Use loaders to define max mining rates, then:

    1. Enter the No of Loaders.

    2. Enter the Capital Cost of each loader in $.

    3. Set the Capacity of each loader.

    4. Choose the predicted Lifespan of each loader (in years).

  5. Save your scheduler settings.
