Maximising Volumetric Efficiency for Ventilation Systems in Temporarily Reduced Flow Environments of Block Cave Mines

It is vital to understand the impact on main and booster fans when the ventilation system is in a state of fluctuation. This paper provides suggestions in generating a plan for temporary reduced ventilation situations in a block cave mine while maintaining safety and maximizing production. This plan was used in maximizing operations for reduced airflow situations at Oyu Tolgoi Mine.
