UNDERGROUND RAIL TRANSPORT INSTALLATIONS AT MOUNT ISA MINES, LTD., QUEENSLAND

During the past eight years the underground rail system at the Isa mine has been upgraded, resulting in an increase in haulage capacity from 3 to 10 million tons annually. This sophisticated haulage system reduced the haulage cost per ton by 15 percent in fiscal year 1974-75. The approach to be taken for the proper selection of haulage rail is described. Installation of the 47 kg/m A.S. rails was based on observations of rail wear and life. Adjustments were made for adverse underground conditions such as ore spillage, heavy braking, acceleration, and inadequate maintenance. Data are given for expected rail life based on rail size and tonnage hauled. A brief description is given of the ultrasonic track-inspection equipment, its use, and the action taken when a defective rail is detected.
