Investigation report released after haul truck crashes into excavator at NSW coal mine

Investigation Report Released After Haul Truck Crashes Into Excavator at NSW Coal Mine

On February 20, 2025, a collision occurred between a haul truck and an excavator at an open coal mine near Muswellbrook, NSW. The NSW Resources Regulator has published an investigation information release covering findings from its inquiry into the incident.

Below, we break down what the investigation report reveals about the sequence of events, along with what this news means for site operators managing similar vehicle interactions.

What Happened During the Collision

According to the investigation information contained in the regulator's release, the haul truck reversed towards the excavator without positive communications established between operators.

"The excavator operator tried to move the excavator out of the truck's path but was unable to do so because of the large size of the truck and the position of the excavator on the bench," the regulator says in its report.

The tailgate and rear section of the truck made contact with the side of the excavator's cabin, causing the front left pillar to bend inward toward the operator while simultaneously lifting the cabin roof. This structural failure left the excavator's cabin significantly damaged, preventing the operator from exiting through normal exit methods.

Why This News Matters for Mine Safety

This news follows a string of recent incidents making headlines across the NSW resources sector, underscoring ongoing risks tied to vehicle interaction on active mine benches.

For teams managing similar plant and equipment, this news serves as a reminder that positive communication protocols between operators remain critical, particularly where large vehicles are working in confined bench areas alongside excavators.
