Open Pit Optimisation

An add-on for Maptek Vulcan

Open Pit Optimisation add-on includes pit optimiser, cut-off grade optimisation, and haulage profile tools.

Pit optimisation streamlines mining strategy evaluation by working efficiently with current geological models. It rapidly incorporates factors like loss and dilution, while adhering to complex geotechnical constraints. This approach focuses on calculating the Net Present Value (NPV) rather than cash flow, offering a comprehensive financial overview based on full mine scheduling.

Engineers can account for complex geotechnical requirements and incorporate different products, costs and processes. Running multiple scenarios simultaneously, with on-the-fly reserving, enhances decision-making efficiency.

Haulage Profile uses stored fleet information to calculate the haulage time between two digitised points, with information stored in the block model for accurate planning. Nodes and segments can be shared between routes and multiple scenarios can be run for evaluation.

Additional Information

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
