Scheduling Setup: Bench Advance

To access this screen:

Display the Optimization task bar and select Optimization >> Scheduler >> Maroma >> Settings >> Bench Advance.

Define sinking rate(s) for the Maroma scheduler.

Define the maximum number of benches a mine can progress in a year (the sinking rate) and optionally choose the maximum daily mining rate for each pushback by elevation value. In essence, this screen determines the sink rate of each pushback.

You also use this screen to set a completion date constraint for each pushback, for example, if a particular pushback has to be extracted by a given year.

To define the bench advance for a pushback:

Define your pushback scheduling settings.
In the Bench Advance (Sink Rate) table, set the Max Benches (the maximum number of benches that can be mined yearly (if no Finish By value is set) or before the finish year.

Note: You can set Max Benches for all pushbacks at once to any value using the controls at the bottom of the table.
Optionally, to set a completion constraint for the pushback, select a Finish By year. If set to None, the pushback finishes when it finishes, according to other parameters.
For the pushback, define the maximum daily mining rate using the table on the right. For each bench Toe Elevation:
- Review the Bench Mass.
- Set the Max Rate/Day = maximum daily mining rate in Kilotons.
- Click Update Sinking Rates to calculate variable per-bench sinking rates based on the maximum daily rate for the bench.
Save your scheduler settings.
