ROM Harp Modelling

Run Of Mine (ROM) capability in Vulcan 9.1 takes a HARP model containing all of the geological structures, horizons and associated qualities as input and allows you to easily create ‘mining ready’ HARP models. These tools are included with any Vulcan geological modelling configuration.

Features and benefits

• Include all numeric quality or mining parameters as constants or HARP model variables
• Simple to define quality parameters for each horizon including values for the coal, waste and material specified as ‘loss’ or ‘gain’
• Apply blanket parameters for all horizons, or define horizons individually
• Define mining loss, gain and recovery parameters for horizons individually or collectively
• Adjust HARP working section block boundaries to reflect new location of ROM roof and floors
• Working sections are named after the horizons contained; burden can optionally reflect this naming
• Fast and simple to set up
• Ideal for running multiple ‘what if’ scenarios for comparison
• All parameters saved to specification files
• Single file input – single file output for simple data management
• Calculate ROM model through faults (reverse or normal), splits, weathering surfaces etc.
• ROM HARP output suitable for reserving and plotting, as well as on-screen analysis and viewing
• Calculation scripts make it simple to apply other, more complex mineability criteria before or after running HARP ROM modelling
