Lundin Mining operates the Eagle Mine in the Upper Peninsula of Michigan USA. The mine is preparing to construct the new Upper Keel zone – another high-grade nickel orebody in proximity to the existing mine. This paper provides an overview on several aspects of the ventilation design and strategy including the options for development and construction, life-of-mine operations, and the innovative ability for on-shift blasting during the construction phase while maintaining operations in the existing Eagle and Eagle East zones.
