Abstract
In 1998, the decision was made to expand the mining at Creighton to a depth of 2493 m. To meet this requirement, major changes in the venilation system were required to provide and acceptable working environment. The previous #11 shaft exhaust system consisted of three horizontal axial flow fans connected in parallel to a concrete plenum. The new ventilation requirements include several duties with ultimate perforamce requirements well above the existing capabilities. There were numerous challenges such as selecting the prper fan type, determing the appropriate arrangement and implementing the project in such a way that the first new duty point could be reached without interrupting mine production. The Inco Fan Specification and the Aerodynamic Fan Document were determined to be paramount to the successful implementation of the new design and installation. The complex project was successfully completed on time and under budget in November 2001 with all thre fans operating.
