MSO2NPV Process

To access this process:

See this process in the Command Table.

Process Overview

Update a model containing ore and waste categories into a model suitable for strategic planning, using Mineable Shape Optimizer (MSO) output wireframes.

A MODOUT1 model generated by MSO2NPV shown with a cutaway of stope wireframes.

The metal content and mass from the stope wireframe data is the same in the block model for the cells representing the MSO shapes, although an optional comparison table is available for analysis. All cells outside the MSO volumes are not considered ore. This process is intended to apply the selective mining units generated by MSO (or by any other means) into the model to be used for optimizing in Studio NPVS.
