A major gold producer operates an underground gold mine in Australia. For rock handling purposes, the mine has a full ore pass system that allows material transfer by gravitation. The 100 m / 328 ft deep ore pass always keeps a certain level of run-of-mine (ROM) ore, which is collected and further transported to crushing and grinding plants.
