Pit Accumulation
Source file: origin-reserve-setups-constraints-model-accumulation.htm
Use the Pit Accumulation constraint to define the maximum volume or amount of tonnes that can be mined per pit per period.
The Item drop-down menu allows you to specify the item to set the accumulation constraint against.
You can apply settings manually in each period, or by copying the entered setting to the next period using the button. To copy the setting to all subsequent periods double-click the button. Alternatively, select a cell with the setting you want and press ctrl + c. Next, while holding ctrl on the keyboard, select all cells where you want to apply this setting and paste it with ctrl + v.
