Stockpile Modelling
The aim of the stockpile modelling functionality is to capture the movement of material going in and out of the stockpile and display that movement visually based on a user-defined design and sequence of movement.
The Stockpile Modelling functionality is broken down into 4 parts:
-
Design: The stockpile string and wireframe model is created using a base string and the defined design parameters. A topography wireframe model can optionally be used to control or refine the design.
-
Evaluation: The evaluation process is used to cut the stockpile up into blocks. These blocks are used to sequence the order in which material is supplied to, or reclaimed from the stockpile and to visually model the process (blocks can be hidden if empty). These stockpile blocks allow for a more realistic and thus accurate modelling of stockpile material movement while scheduling as, rather than using an average stockpile grade at that point in time, grades are calculated on a stockpile block basis.
-
Sequencing: The sequencing process is used to define the entry point(s) to the stockpile(s) as well as the planned rebuild and reclaim sequences. The latter are generated either manually, automatically or by using dependency order guide strings.
-
Using a Stockpile Model with a Stockpile Destination – Stockpile Destinations can optionally make use of stockpile models - set in the Stockpile Destination Settings Model tab). If they are modelled, extra options are available, such as initial state per stockpile block and swell factor. When modelled, the visual representation of their material will be shown in the wireframe and the ‘Show Stockpile Blocks’ view will give information based on the individual blocks rather than the stockpile as a whole.
Stockpile Design
The general procedure for doing this is as follows:
-
Draw or load the stockpile base string(s) into the 3D window.
-
Select a base string.
In the Task Pane, Setup tab, click Stockpile Design .
