Materials

Material types are defined by rules that return true when the condition is met. The material types are used throughout XECUTE and are evaluated at block level. Materials define block model aggregation classes in reporting and scheduling, and are used to route mined quantities to destinations.

Material rules are evaluated in order from the first in the list to the last in the list. Rules are typically designed to be exclusive however non-exclusive rules are possible. For example:

Rule1: Fe > 70

Rule2: Fe > 50

Rule1 will be assigned all material > 70% Fe

Rule2 will be assigned all material > 50% and < 70% Fe because Rule1 appears first in the list and takes priority in material assignment.

Once materials are defined they can be enabled for a Pit. Pit-enabled materials are evaluated for all activity areas in a pit and any blocks that do not match the enabled material rules will be assigned the pit default material.

  1. Click the Materials icon.
  2. Click Add to add a new material.
  3. Enter a Name and Expression.
  4. Set the Swell Factor to apply to the material upon it being mined. The swell factor is applied to the block model volume (In Situ volume) and is carried in the Swollen_Volume principal field. The block model InSitu volume is carried in the Volume principal field.
  5. Click Save to save the newly created material, or click the button to save the current item and create a new one. Movement Materials should have mutually exclusive definitions.

Deleting materials

When a material is removed from the system configuration, a series of checks are performed and a dialog displays if the removal will result in an invalid configuration.

Click the Copy Usage button to download the deletion report.

There is no undo action for deleting a material.

Deletion will not proceed (the Delete button will not display) if the material is used in:

Delete is not blocked, but you will still be asked to confirm the deletion if the material is used in:
