Summary: A haul truck was reversing into the pit dump behind a dozer that was positioned and working perpendicular to the haul truck. The dozer reversed into the haul truck making contact between the ripper frame on the dozer and a tyre on the haul truck. The wheel rim was scored and scuffed. No escape of air occurred from the tyre.
Recommendations to industry: Mine operators should review how the hazards associated with machine interaction are controlled. Such a review should consider:
- positive communications
- proximity detection technology
- job design (segregation)
