The NSW Resources Regulator has released an excavator and dozer collision incident that occurred at an open cut coal mine.
An excavator collided with a dozer causing significant damage to the cabin. The operators had established positive communications to allow the dozer to enter the excavator’s swing radius. However, the excavator operator restarted operation without confirming that the dozer was clear of the swing radius.
The Regulator stated: “to control the risk of collision excavators should cease operation while dozers are operating within the swing radius. Mines should not rely on procedural controls for managing the risk of collisions. Collision avoidance technology should be integrated into mobile equipment.”
