Abstract
ABSTRACT Load Haul Dump (LHD) equipment, haulers, and locomotives are essential to both hard and soft rock mining. Key performance indicators were calculated for both diesel and electric LHDs using the data provided by a multinational mining company operating metal mines. Battery-powered vehicles, having both the advantage of low maintenance and no tether to haul, showed an improvement in uptime. The electric fleet was, on average, operational 11 h longer than diesel vehicles before they are pulled off for maintenance. The results from comparing diesel and electric equipment show that the best equipment would be a fusion of the reliability of electric vehicles and the mobility of diesel equipment, both being attributes of battery powered equipment. Battery-powered vehicles are constantly improving and will only increase their prowess over diesel equipment.
