PS Preschedule

Set the proportion remaining to drill, charge, or mine.

Set the ratio remaining in each activity, in each record.

Field	Usage

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’ drop-down box after preschedule has been applied.
Total	The quantity of the field selected in the ‘Display Field’ drop-down box before preschedule has been applied.
Delays (days)	The number of days before the selected activity can proceed on a record. I.e., At the beginning of the plan, a blast maybe 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.

Single Record Preschedule

Select an activity from the Activity list.
Expand the record tree to the blast or dig solid.
Set the proportion remaining.

Bulk Preschedule

Select an activity from the Activity list.
Expand the record tree to a given level.
Right click > Set Values to > Amount remaining.

Automatic Preschedule from Surface

Right-click anywhere in the level tree > Automatically Deplete from Surface.

Select preschedule surface, records, and activities.

Graphical Preschedule

Click ‘Edit Preschedule Graphically’.
Select Reserves Shading <Proportion Remaining (Activity)>
Select one or more blocks for prescheduling.
Right click > Specify Remaining Value > Enter value > OK.

Graphically select blocks to preschedule.

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.
