The Significant Intercept Calculator

This tool calculates and stores results for significant intercepts, based on a set of predefined criteria. Intercept schemes are configured by the OCRIS data administrator (see later).

 

Select a configuration in the list and click Execute (or double-click on the row) to open it.

The configuration comprises one or more default intercept schemes. An intercept scheme specifies the physical constraints and quality constraints that control the optimisation process  (such as waste and grade cutoff values). When the intercept calculator process is executed, one or more selected intercept schemes are included in the run.

The physical parameters associated with each intercept scheme are summarised in the top data frame, while the quality constraints defined for the selected scheme are displayed in the bottom frame.

Intercept calculator configurations may change over time; therefore, all the metadata for a given scheme is stored along with the intercept results generated by the process. Each new instance of a scheme that is stored in the database is referred to as a scheme variant.

Tick the check boxes of the scheme or schemes that you wish to include in the current process, then click Execute to proceed.

Depending on the configuration, you may be asked to specify selection criteria to be applied when retrieving data from the database. To specify your criteria, select each parameter in turn in the parameter list displayed on the left side of the window, then fill in the required details as prompted in the pane on the right.

Click Continue to start the intercept calculation process.
