GCOPT

This option is used for two tasks, either the block based optimization or the polygon based contouring.

Block based optimisation generates a block model automatically using the blasts loaded into Vulcan. If you are using the block based optimization you do not need to specify a database, or if it should be compressed and rebuilt.

Polygon based contouring is used to generate optimal operational polygons from an underlying economic block model, with respect to economic value. It is especially useful for generating grade control polygons which will increase revenue and reduce tedious drafting work at open pit mines.

Usage:

Where:

Example:

Block optimisation

gcopt -e 1200.00 model.bmf spec.gco.spec scenario01

Polygon optimisation

gcopt -d thor.dgd.isis -c -e 1200.00 model.bmf spec.gcp.spec scenario01

Note:   There is a different specification file used in each case. The first is a gco.spec, and the second is a gcp.spec.
