This command uses a max flow algorithm to determine the ultimate mineable economic pit. This is an automated routine with very few prompts. When the command is started, the first prompt is for a value block model (*.BM file). This file is created from the Prepare Value Block Model command which must be run before the Optimized Pit Design to create this file. After selecting the value block model file, the first dialog will then appear to set the slope angles on the various sides of the ultimate pit.
After setting these angles, and selecting OK, the program will
create a .TIN file of the optimum pit. The surface uses the blocks
in full to create the slopes, which can look like benches if the
blocks are made at the proper size in the original block model.
This TIN file can then be viewed in 3D, contoured, or used to
create linework for other pit design routines, such as Design Bench
Pit.
The command line displays text after the command stating the
monetary value and the volume of the total blocks.
