Stage Release
The Staging > Stage Release tab was set up to indicate which stages are available for mining on a per period basis. Stages that are made available can have additional, tonnage-based constraints applied to them. These constraints are summarised below:
| Constraint | Restriction | Description |
|---|---|---|
| Tonnage Constraint (TC) | Equal to | Constrains the material set as Tonnes in Flowchart > Configuration > Pit. Once the tonnage has been achieved, the stage becomes unavailable for the selected period. |
| Ore Constraint (OC) | Equal to | Constrains the material set as Ore Tonnage in Flowchart > Configuration > Mill. Once the ore tonnage has been achieved, the stage becomes unavailable for the selected period. |
| Tonnage Target (TT) | Minimum amount | Refers to the material set as Tonnes in Flowchart > Configuration > Pit. The stage must achieve a minimum ore and waste tonnage for the selected period. |
| Ore Target (OT) | Minimum amount | Refers to the material set as Ore Tonnage in Flowchart > Configuration > Mill. The stage must achieve a minimum ore tonnage for the selected period. |
| Maximum Constraint (MC) | Maximum amount | The stage may achieve up to a maximum tonnage. Once this tonnage has been achieved, the stage becomes unavailable for the selected period. |
The Stage Release tab can be used to group stages. To create a stage group:
- Go to the Configuration tab.
- Add the stage group by clicking the green plus sign and then selecting the checkboxes.
To delete a stage group:
- Select the stage group from the list and click the red minus sign.
