Pit Accumulation

Source file: strategy-setups-constraints-pit-accumulation.htm

Use the Pit Accumulation constraint to specify the maximum accumulation value for a given model, on a period by period basis. You can use this constraint to limit items like the following:

• Ore tonnes

• Total tonnes

• Drilling hours

• Acid consumption

• Contaminant levels

Follow these steps to determine pit accumulation for each period:

1. Select the pit model from the Item drop-down.

2. Select the accumulation variable from the drop-down menu.

3. For the selected variable, specify the total amount that can be mined from the selected pit in each period.
