PS Preschedule
- iarmstrong
In the Preschedule step set the proportion remaining to drill, charge, or mine.
Preschedule step screen elements are listed below.
Field | Usage |
|---|---|
Proportion Remaining | The percentage remaining in every sum field for the selected activity |
Remaining | The quantity of the field selected in the Display Field dropdown list after preschedule has been applied |
Total | The quantity of the field selected in the Display Field dropdown list before preschedule has been applied |
Delays (days) | The number of days before the selected activity can proceed on a record. Example: At the beginning of the plan, a blast may be halfway through pattern prep. A delay can be used to represent the remaining duration of the prep time, preventing the blast from being drilled straight away. |

Click Edit Graphically button.

Select one or more blocks for prescheduling.
Right click > “Specify Remaining Value for Selected Blocks” option > enter new value in a dialog > OK.
Manually prescheduled elements are shown in green bold in the tree hierarchy.
Blocks set for mining as 0 remaining, will appear in graphics with 0 tonnes and 0 bcm. To remove completely use the Record Removal step.
Prescheduling does not recognise where material is spatially, just that a % of the block has been mined and the inventory of all parcels is reduced by that %. It is recommended that mining prescheduling with a depletion surface is done in Rapid Reserver which will remove material from the correct location spatially.
