Using Location Constraints in MineSched

By

For GEOVIA MineSched™ users, when setting up a scenario, it’s important that all the parameters are correct. Part of this configuration consists of selecting the location(s) where the material will be mined. There are many different options available to set up the Locations in MineSched.

To begin the process, select the Locations option in the “Setup Schedule” Tab. Click the “+” button to insert constraints.

There are nine 9 different types of constraints in which to configure the locations and combine them for more accuracy in selection.

Surpac Constraint File
You can use a Surpac constraint file (.con) previously created in Surpac. This file will include the blocks that belongs to the location.

Surface
Another option to setup a Location is the Surface option. After selecting, you can decide if the constraint will apply above or below (not above) the surface.
Types of files supported: Surpac files (*.dtm); GEMS Project Files (*.gpr); Minex Files (*.tr5); AutoCAD Files (*.dwg, *.dxf); Datamine Files (*_tr.dm, *_tr.asc, *_tr.dat, *_tr.ddf); Micromine Files (*.dat); Vulcan Files (*.00t)

Solids
If you decide to use a Solid constraint to define your location, you should click the Inside box to use the blocks inside the solid, or unclick the Inside box to use the blocks outside the solid.
Types of files supported: Surpac files (*.dtm); GEMS Project Files (*.gpr); Minex Files (*.tr5); AutoCAD Files (*.dwg, *.dxf); Datamine Files (*_tr.dm, *_tr.asc, *_tr.dat, *_tr.ddf); Micromine Files (*.dat); Vulcan Files (*.00t)

Polygon
If you use the polygon option, you need to be sure that the lines are closed. You should click the Inside box to use the blocks inside the polygon, or unclick the Inside box to use the blocks outside the polygon. In “Extend direction” option, enter the direction in which the polygon extents are extended until they intersect the extents of the model.
Types of files supported: Surpac files (*.str); GEMS Project Files (*.gpr); Minex Files (*.gm3); ArcInfo Files (*.shp); AutoCAD Files (*.dwg, *.dxf); Datamine Files (*_pt.dm, *_pt.asc, *_pt.dat, *_pt.ddf); MapInfo Files (*.mif, *.tab); Micromine Files (*.dat, *.mm, *.str, *.out); Vulcan Files (*.dgd)

Block
You can select an attribute in the block model and use it to constrain the blocks that will be used for the Location. After select the attribute, select the operator and enter a value. All blocks that meet the requeriment will be included in the Location.

X Plane, Y Plane, Z Plane
You can select the portion of the model above or not above the plane selected. The other portion of the model is excluded from the Location.

Plane
If you know the Scalar Equation of the Plane, you can enter the coefficients A, B, C or D and use that plane as restriction to define wich blocks will be used in the location.
