Survey of Surface Mining Accidents—Mobile Equipment

A survey of mobile mining equipment related accidents occurring in surface mining operations indicates that in 1978 there were 19,545 non-fatal injuries. Mobile equipment as defined in this paper was involved in 3,029 or 15.5% of these nonfatal injuries. Dumpers and front-end loaders were involved in 51.3% of these mobile equipment related injuries.
