Define Boundary Orientation

These settings are typically used to control stope shapes constrained by a reference surface, such as a geological boundary.

For more information on the MSO boundary optimization method, refer to the latest MSO manual.

AMS MSO Manual – Section 4.1.3: Boundary Optimization Method

Covers stopes constrained by a reference surface, such as a geological boundary. Includes details on surface-normal orientation and stope parallel alignment to boundaries.

Note: The MSO manual is installed with each copy of Studio UG. If you are using a different Studio product and require a copy of the MSO operating manual, please contact your local Datamine office.

Activity steps

Create or select an MSO scenario.
If not already defined, specify a block model.
Set up the run economics.
Display the Orientation screen.
Expand Optimization Method and select Boundary.
Expand the Boundary Orientation command group.

Choose Orientation settings for your Boundary framework:

Geometry	Orientation	Description	Typical Use Case
Vertical	Boundary Surface XZ	Reference surface is aligned along the XZ axis.	Vertical veins striking north-south, mined in east-west-oriented stopes.
	Boundary Surface YZ	Reference surface is aligned along the YZ axis.	Vertical veins striking east-west, mined in north-south-oriented stopes.
Horizontal	Boundary Surface XY	Reference surface is aligned along the XY axis.	Flat-lying deposits like coal seams or horizontal tabular orebodies.
	Boundary Surface XY	Reference surface is aligned along the XY axis.	Stratiform or bedded ore zones requiring Y-axis referencing for stope layout.

Constrain your framework by defining Framework Extents. Extents can either be defined using a block model prototype or manually entered values to determine a bounding cuboid:
- Block Model – Select to constrain generated data to the outer hull of the current scenario's block model.
  - Optionally, check Show Block Model Prototype to display the current Origin, Distance (axis length) and Offset values below.
  - With prototype values displayed, check Visualize in 3D and click Look At to display the cuboid prototype in the primary 3D window (and all linked windows). This can help to see how the model boundary relates to other reference data.
  - If the input model is rotated, axis Rotation angles also display (otherwise, they all show zero).
- Manual – Explicitly define a cuboid in 3D space by defining the Origin (world coordinates please) and Distance (local length) of the major axis. For a rotated cuboid, specify up to 3 rotation Angles for XYZ.
  Note: When defining world coordinates, these are described as XYZ, where local framework coordinates are described through these help topics as UVW.
  - Optionally, click Copy from Block Model to transfer the existing model prototype details to the editable fields. This could be useful, say, to create a bounding cuboid that is larger than the input model, for example.
  - Check Visualize in 3D and click Look At to display the cuboid prototype in the primary 3D window (and all linked windows).
  - Optionally, check Show Block Model Prototype to display the current Origin, Distance (axis length) and Offset values without transferring them to the editable fields.
Use Additional Settings to select the reference Wireframe surface to be used to bound the results.
Save your settings.
