Ventilation and Production Optimization (VPO)

Ventilation and Production Optimization (VPO)

VPO delivers much of its research through decision-support software. We also facilitate visualization of complex datasets in the VRL (virtual reality laboratory). Potential clients and collaborators are invited to approach us with industry challenges that require innovative solutions.

Our research areas include:

Projects:

• SOT

  • SOT (Schedule Optimization Tool) is MIRARCO's first commercial software application. Officially launched in 2008, SOT is designed to save mine planners time and generate near-optimal mine schedules based on operational constraints and financial parameters. SOT is distributed through GijimaAst and CAE Mining, and is integrated with the widely used Enhanced Production Scheduler (EPS). Development is ongoing with new and improved versions being released regularly.

• SOT+

  • A three-year research project is being undertaken to extend the application of MIRARCO's Schedule Optimization Tool (SOT), resulting in a new mine plan optimization tool called SOT+. More information can be found here.

• Multi Period Mine Ventilation Optimization

  • The objective of this research is to create an algorithm that produces optimal or near optimal mine ventilation designs based on a given schedule accounting for minimum energy cost. A mathematical approach is used to generate economical mine ventilation design to support the mine schedules. By accounting for ventilation requirements in a multiple period mine, the net present value of the mine is improved in two ways: minimizing ventilation costs and reducing production and development losses due to inadequate ventilation planning.

• Natural Heat Exchange Area

  • Researchers are assessing and optimizing the refrigeration capacity of the fragmented rock mass in the old open pit of Vale's Creighton Mine. The project involves building a ventilation model of the rock mass and determining how to best use its natural cooling capacity throughout the year. Optimal use of the rock mass will be determined with the help of an optimization algorithm that uses artificial intelligence in the form of a genetic algorithm. The goal of this project is to delay the use of mechanical refrigeration as the mine reaches the 8000ft level and beyond.

• Virtual Reality

  • The Virtual Reality Laboratory allows for immersive 3D presentations before a 3.9 million pixel, 22 foot concave screen. Several datasets can be combined into one comprehensive model for efficient property and technical reviews. MIRARCO facilitates VRL presentations for your organization for investor relations purposes, mine planning and design, exploration reviews and training sessions.
