AbstractIt is estimated that 61% of electrical energy consumption in underground hardrock mining operations is accounted for by ventilation and air compressors. These costs are further escalated as a result of increasing utility rates, current trends in workplace health and safety practices for more stringent legislation affecting ventilation, and expanding mine operations. These escalating energy costs can be reduced by controlling air delivery when and where necessary, recovering waste heat from mine ventilation and compressors, and utilizing it during winter months. Additional savings can be achieved by using alternate mining equipment. The tendency to conserve energy costs in mines also promotes the design and development of new and efficient equipment and mining methods.
Recent developments in sensors, instruments, materials, and computer technologies now permit energy management and the automation of such systems. CANMET has been pursuing energy conservation in mines for a number of years. This paper summarizes electrical energy costs and potential savings in Canadian underground mining operations.
