Running the Pit Optimization

You can run the pit optimization accoding to the specifications you defined for the pit case scenario to view and review the optimization results.

Before you begin:
  • Open a site, a source block model, and a terrain surface. See Preparing for Your Pit Optimization Session.
  • Create at least one scenario. See Creating a Scenario.
  • Define the pit optimization parameters required for the scenario. Double-click on the headings below the required case to view or update the defined parameters.

Controlling the Run Speed
  1. Only one set of pit optimization results can be active at a time. Change the required set of results to be active, right-click the label of the required results then select Set as Current.
  2. From the Pit Optimization section of the action bar, click Run Pit Optimization.
    The Pit Optimization dialog box appears to provide an overview of the defined parameters.
  3. Review the displayed parameters. Some parameters are required such as the economic scenario. If the required parameters are not specified, Run is unavailable.
    1. Review the Inputs. See Modifying a Scenario. You cannot change the block model.
    2. The Economic Scenario is a required parameter. Review the Economic Scenario. See Defining an Economic Scenario.
    3. If the Pit Slopes are not defined, they are set to the default of 45 degrees. Review the Slopes. See Defining Slope Profiles.
    4. Run Control is a required parameter but is set to no by default. Review the Run Control. See Controlling the Run Speed.
    5. Phases are required to successfully run the optimization. Review the Phases. See Controlling Pit and Phases.
    6. Scheduling is an optional parameter. Review the Scheduling. See Enabling Scheduling.
  4. Click Run. Click Cancel at any time to cancel the run.

    The validity of set parameters is verified at the start of the run and if there are errors they are displayed in the run status area. The run status area also indicates the status of the run and displays a progress.

The pit optimization is run and results are generated. If the run fails, hover over the Failure Icon

for more information about the failure.
