ABSTRACT
Design of safe and efficient ventilation system is always very important aspect of the design process of any underground mine. However, when the mine being designed is the largest uranium mine in the world, the ventilation system becomes the most important aspect of the mine design process. The paper discusses the design process and its implementation of the ventilation system at McArthur River Mine; currently the largest and highest-grade uranium deposit in the world. The paper includes description of the mine ventilation network, mine main fans and heaters arrangements, and also points out many challenges and their solutions to the design and implementation process of the ventilation system at underground uranium
