Define Waste Pillars (Prism Framework)
This section of the Shapes screen can be used to define how much separation is enforced between stopes in a Prism framework.
The aim is to enforce minimum separation distances between stopes, ensuring stable waste pillars are maintained.
Note: These settings can be used to fine-tune the optimization of this framework type, and are all optional.
In Prism optimisation, stopes are selected from a pool of candidates. Without separation rules, overlapping or unstable designs could be chosen.
You would typically adjust these settings when:
-
Designing for geotechnical stability.
-
Enforcing mine design rules.
-
Preventing over-extraction.
Activity steps:
-
Display the Shapes screen.
Note: The activity outlined below is specific to the Prism framework type. Other framework types present a different screen.
-
Check Use Waste Pillar Separation.
-
Enter minimum separation distances for U, V and W axes.
Note: U, V and W are the local coordinate directions of the stope framework.
-
Save your settings.
