Sink Rate

The Sink Rate is the mining duration per bench. It limits the vertical advance rate of the schedule based on the total tonnes available for mining on a bench and the corresponding dig rate.

This constraint allows for variable dig or production rates based on definitions that you provide. For example, a bench may have just enough area and therefore tonnes for one digger per unit of area. In that case, you can define these values and reference a dig rate for the single unit. However, if the tonnes on a bench are more than this specified range, Origin will check the constraint setup and use the appropriate mining rate defined by the larger bench tonnage.

To add multiple production rates at once, click , select the required number and click Add.
To delete production rates from your setup, select the checkboxes that correspond to the production rates you no longer need and click Delete the selected sink rate.
