– Electricity Generation in Underground Mine Service Shafts


A feasibility study conducted in February 2019 on the possibility of generating electricity in the service shaft at the Westwood mine demonstrated the site’s energy potential and the return on investment. The project involves installing turbines over the fresh air duct in the service shaft and reusing the existing reservoirs to release the water back into the duct. This makes it possible to recover the heat lost at each level, considering that maximum power can reach 80 to 100 kW per level.
