Cost Analysis of Controlled Partial Recirculation of Mine Ventilation Air At Mount Isa Mines
Abstract
The Mount Isa mines in Australia are located between 1,200 to 1,800 m below the surface and are characterized by steep geothermal gradients, intensively mechanized stoping methods and high ambient air temperatures in summer. The mines require some 550 m 3/s in ventilation air quantity when the production rate is greater than 2.5 million tonnes per year. When production rates are greater than 3 million tonnes per year, either new intake and return airways will need to be developed or innovative approaches such as controlled partial recirculation used. Technical and economic investigations of the controlled partial recirculation system used at the Mount Isa mines show that an acceptable working environment can be achieved practically and economically.
