a collision between dozer and haul truck

The NSW Resources Regulator has reported a dozer and haul truck collision incident occurred at an open cut coal mine.

According to the report, a dozer and a haul truck collided at a tip head. Both vehicles were reversing at the time of the incident. A preliminary investigation suggests that the truck operator did not follow the site requirement for positive communications with the dozer operator.

The Regulator said machine operators should not rely on the experience or previous movements of other operators as a substitute for positive communications. Lack of positive communication has been the root cause of many incidents and mine operators must consider higher-order controls including proximity detection. Mine operators should consider periodic refreshers in positive communications protocols for operators using mobile equipment.
