TS. Long Term Stockpiles
The Long Term Stockpiles step allows users to configure the reclaim conditions of long-term stockpiles.
This gives users the ability to send material to a dump and then reclaim the same material at a later time.
Use cases include modelling large LG stockpiles, rehabilitation, and land bridges.
Adding a Long Term Stockpile and displaying this setup task
Create Tables
In the Create Tables step in the Type column select “Long Term Stockpile” option. This table type behaves exactly the same as other table types and can be assigned to phases in the “Map Fields” step.
Map Fields
In the Map Fields step, map phase as a Long-Term Stockpile.
Preschedule
Phase mapped as long-term stockpile appears as Source and Destination in the Preschedule step.
Long Term Stockpiles Scheduling logic
Destination Logic and Steps Logic
The source and destination phases can be referenced in the Destination Logic and Steps Logic to handle the movements to and from the Long-Term Stockpile.
Phases assigned to this table will be added as both a fillable destination and a reclaimable source.
Note that Long-Term Stockpile is not a standard stockpile node, but a source to be mined at some point in time, it only can be mined with a Mining Agent and not a Stockpile Reclaimer.
Long Term Stockpiles Triggers
In the Long Term Stockpiles step each entry in this table consists of a long-term stockpile, reclaim parcel and a trigger condition.
Reclaim Parcel - The parcel that is reported out in the transactions that occur from mining the stockpile. This is the parcel that the material dumped on the stockpile becomes, so it should be used in the destination logic rule for reclaiming.
Trigger - The condition that must be satisfied to allow reclaiming to commence. This is the same logic that is applied in Dynamic Haulage rules.
AnyMined - The trigger is fired when any ONE of the blocks specified finishes mining,
AllMined - The trigger is fired when ALL blocks specified have finished mining.
Calendar - To control LTSP reclaiming from the Calendar. Set a value greater than 0 in the periods when you want to start reclaiming.

Reporting
Create a report to view the tonnes (and parcels) moved to and from the LTSP by period. Filter by LTSP as Source and as Destination to make it easier to view the data. You can also display the applicable destination or step logic rule to validate the setup.
Notes
Keep in mind that if you are using Assigning Joins based on Segment Names function in Haul Infinity, your blocks connection to the network may need to be updated.
