Sink Rates

The Sink Rate is the mining duration per bench. Based on the total tonnes available for mining on a bench and the corresponding dig rate, a sink rate is determined by the software. You provide this information using the Sink Rate constraint.

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 1 digger per unit of area. You will define this 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 set up and use the appropriate mining rate defined by the larger bench tonnage.
