Bulldozer Over Highwall
A bulldozer recently fell over a 32-foot highwall at a District
8 surface mine. Its operator was leveling and cleaning the
parting bench in preparation for blasting. The bulldozer
continued over the edge while pushing unconfined material and
flipped onto its top after the blade struck loose material that
had collected at the bottom of the highwall. Using a cellular
phone, the supervisor immediately called for medical assistance.
The operator received a laceration on the top of his head and a
fractured vertebra. Seat belts were being worn which likely
prevented a more serious accident.
- Maintain the equipment's FALLING OBJECT PROTECTION and its
fastenings in good condition.
- Mobile equipment operators should always wear snug fitting
- Operators should always maintain at least a blade's width of
material between the bulldozer blade and the highwall.
- Always push perpendicular to the edge.
- Operators should always maintain positive equipment
