Open Pit Optimisation

Open Pit Optimisation add-on provides specialised tools for creating surfaces and previewing designs for optimising pit limits, cut-off grade techniques for mine planning, and analysing haulage cycles.

• Run scenarios to determine the cut-off grade profile based on Lane's algorithm to account for mining, milling and refining to maximise NPV
• Create haulage networks based on speed or rimpull curves to estimate cycle times, productivity and distance
• Export output to CSV/Excel or store in the block model
• Create equipment databases to ensure consistency during the haulage process
• Work directly with a block model with the ability to reblock on the fly

• Pre-calculate the economic block value or use standard methodology (i.e. Revenue/Cost)
• Flexibility to model complex geotechnical domains
• Sensitivity analysis around economical parameters to understand the impact of the size of the pit
• Embedded animation tools to visualise the results of the pit optimisation process
• Choose between standard Lerchs and Grossmann or push-relabel algorithms
