Red Lake Mine Expansion

With the results of the Computational Fluid Dynamics (CFD) modeling, VIRTUAL designed the Return Air Rise (RAR) system for the gold mine expansion in northern Ontario. The RAR exhaust system consists of two (2) - 250,000 cfm exhaust ducts, inlet silencer and return air fans. Each of the 2 ducts measure 2.1 m x 2.1 m (7 ft x 7 ft) and the total length of the exhaust fan system was 24 m (78 ft). VIRTUAL prepared the 3D model of the system using Autodesk Inventor then prepared the complete mechanical design and fabrication drawings, welding details and Bill of Materials. Using CFD and the Inventor modeling program we were able to design an extremely energy efficient and silent mine exhaust system. In fact this system is 15-35% more energy efficient than a traditional mine exhaust system.
