Oyu Tolgoi Boxcut and Decline Project - Mongolia

  • Resources
  • Resources infrastructure
Working with Thiess, our challenge was to optimise ventilation for the Oyu Tolgoi Boxcut and Decline Project in Mongolia.

EIC Activities optimised ventilation for drill and blast construction of twin 6.5km declines. 

The team participated in value engineering meetings with selected vendors and assured technical system compliance and the introduction of design enhancements. 

The solution reduced fan power (50%), heating (20%) and ensured capital cost remained to budget.
