A primary jaw crusher operator on a surface gold mine heard a noise coming from the crusher and went to investigate. The operator stood on a viewing platform well above the moving jaws to try to determine the source of the noise. A piece of tramp steel was ejected from within the crushing chamber of the machine, narrowly missing the operator, and cannoned into the crusher control cabin some 15m above, causing serious damage to the structure before ricocheting onto a steel beam and then landing back within the jaws. Subsequent examination showed that the tramp metal was a ripper boot from a large bulldozer.
