Setting up stockpiles |

|
In an XPAC schedule, material is moved from a source to a destination. The source may be the deposit or a stockpile and the destination may be a stockpile or a dump. All sources and destinations within an XPAC project (namely the deposit, stockpiles and dumps) are represented by hierarchical records in the Main database.
Deposit records can only be scheduled from. |
- They are Source records only. |
Stockpile records can be scheduled from or dumped to. |
- They can be Source or Destination records. |
Dump records can only be dumped to. |
- They are Destination records only. |
Stockpile records are the only records which can be both scheduled from and dumped to, that is they can be source and destination records.
Stockpiles form one of the three sections within a Main database, the other two being Deposit and Dump. Each Stockpile that you create in your project must be given a name and these names are used as the level 1 record names. The stockpiles are further broken into piles (level 2 records) and parcels (level 3 records). Unlike the Deposit and Dump sections of your Main database, the Stockpile level names cannot be modified.
Each stockpile is subdivided into a number of piles. The size of these piles is user defined and is based either on the quantity of material within the pile or the time spent on construction. Each pile is represented by a record on level 2 of the database, under the stockpiles parent record. Sequential integers are used as the names of each pile.
If the stockpile has been modelled as average, all material moved to the stockpile is added into a single pile (on level 2 of the database, under the appropriate stockpile parent record). In this case there will be no parcel records.
However, if the stockpile has been set to LIFO, FIFO or Unrestricted, each parcel of material moved to a stockpile can be reclaimed individually and so these must be stored as separate records. These records are called parcels and they are created on level 3 of the database under the appropriate pile record.
The records associated with a pile are only created when the pile is complete, regardless of the stockpile properties. Until this has occurred, they are not available for scheduling.
You can use XPAC Analysis Reports to create a stockpile report. See Analysis Reporting Module for more information.
