The NSW Resources Regulator is investigating how a dump truck and a dozer collided at Mangoola mine.
The incident happened on October 5, 2020 at about 9am at the Glencore open cut mine at Wybong west of Muswellbrook when an experienced dozer operator was working on a tip head.
The Regulator says in their investigation report that "a truck operator arrived at the tip head and was unsure where to unload but recalled an earlier instruction from the dozer operator to tip against the wall,"
"The truck operator reversed to dump the load. The truck operator heard a thud and stopped the truck. The haul truck and dozer had collided."
The haul truck operator had 11 weeks industry experience and 4 weeks of experience at Mangoola mine.
The dozer operator sustained some soft tissue injuries and was taken to hospital for a medical review.
The NSW Resources Regulator has commenced an investigation to determine the cause and circumstances of the incident. The Regulator said the investigation will, among other things, consider communication between the operators, training and supervision, as well as adequacy of policies and procedures relevant to the incident.
Glencore, the mine operator is cooperating with the investigation and a report will be published when the investigation is concluded.
The Regulator has outlined what mine operators should ensure they do in these situations:
- ensure that positive communications (pos-coms) is effective between operators when haul trucks are approaching dozers working on tip heads
- engineering controls, such as proximity detection, collision avoidance systems and cameras can assist in managing the risks associated with mobile plant interactions
- review the adequacy of surface transport management plans including tip head procedures for effective radio and communications protocols
- ensure the risk controls for mobile plant interaction are being adequately monitored and verified by audit as being effective.
