Stage Bench Turnover
It is advisable to limit the number of benches per stage in a period at a given time to save costs and ensure safety.
Use the Stage Bench Turnover constraint to restrict the total number of benches mined per stage in a period.
To configure this constraint:
-
Click on a cell in the table that belongs to a particular pit, stage, and period.
-
Enter a value. This will represent the maximum number of benches in that period that can be mined in total. In the example below, we set the maximum number of benches in Period 1 for stage 8 of the pit Au_demo_new_phase.
Note: If you apply this constraint, you cannot apply the Maximum Active Benches constraint.
After you generate your schedule, you can view your results in a pivot report. To open your results in a pivot report:
-

You can now see which benches have been mined in each period.
