Resource Optimisation

This topic provides a summary of new features and enhancements related to Stope Optimisation and Pit Optimisation.

Algorithm

The Lerchs-Grossman Lowest Label (pseudoflow) algorithm for Pit Optimisation has been improved to take advantage of multi-core processing and the 64-bit architecture of modern computers.

 

Analyse Pits

On the Mining tab, in the Resource Optimisation group, when you select Pit Optimiser | Analyse Pits to perform open pit analysis, a progress bar now reports the Stage Number for nested pits and will also report the Bench Number or the Stope it is currently processing.

 

Optimisation Limits

When custom optimisation limits are not set on the Mine > Definition > Model > Block Model page of the Mine Setup form, stope wireframes are no longer clipped to the block model. Instead, extents are calculated based on the area that all slice regions take up.

 

Report Generator

The Stope Optimiser and the Pit Optimiser can generate detailed report files from one or more data sources. When you use the Report drop-down on the Output > Report Data Sources grid to select the name of the data source to be reported for each report, the option to use a Report Generator form set to generate and format the report is now extended for Extraction and Summary reports.
