Input costs and, specifically, escalating energy and electricity costs have become one of the biggest expenditure drivers of deep level mining. However, safety and health remains of paramount importance and cannot be compromised to accommodate electricity cost savings. In an attempt to reduce the operating costs of ventilating an existing deep gold mine in the Free State of South Africa, an optimisation study was conducted on the ventilation and refrigeration systems currently in use at the mine, while maintaining impeccable safety and health standards. This paper describes the methodology used and the outcome of the optimisation study.
