Pit Optimization Settings: Options

To access this screen:

  • Optimization task bar >> Ultimate Pit >> Settings >> Options tab.

Configure general options for generating the Ultimate Pit Optimal Extraction Sequence (UP OES).

Note: For a more detailed explanation of the slope definition process, see Pit Optimization.

Activity steps:

  1. Display the Options screen.

  2. Define the Initial topography, the default is the topography derived from the deposit block model but can also be any imported or generated surface. Choose Use default or select a data file defining the surface and enter the Pit code (the ID of the surface within the file).

  3. Choose the constraining Pit limits. The ultimate pit extent can be restricted by digitized or imported outlines stored as Pit Limit Objects. The default is No Pit Limits but you can also select a data object.

  4. Smooth pits are essential for generating practical pushbacks. Check Generate final pit with minimum bottom width to remove the narrow bottoms of the ultimate LG pit. The nested LG phases generated inside the smooth pit will not be adjusted and will contain narrow bottoms.

  5. Enter the desired minimum Mining width in meters.

    Tip: This value needs to be higher than 100 meters to have any noticeable effect on the calculated ultimate pit.
