Coal mines investigate heavy vehicle mishaps

Authorities are examining incidents at two mining operations in New South Wales.

The state government is investigating a recent truck accident at an undisclosed open-cut coal mine.

The single-trailer road truck overturned while the driver tried to move to stable ground. He tried to dump a load at a stockpile but found the heavy vehicle was too “unstable” at the first stage of the lift.

“On the second attempt [to turn] the trailer and cabin of the road truck overturned,” the NSW Resources Regulator said in a public statement.

“The truck operator was helped out of the cabin by first responders and an ambulance was called to the site [and] the truck operator was cleared of significant injury.”

The regulator urged all mine operators to identify all work activities on the mine site where trucks are used. Risk control measures should be reviewed to prevent a truck roll and mitigate the risk of injury.

Meanwhile, a haul truck failed to unload material onto a working dump face at a different open-cut coal operation.

“When it went through a windrow and came to rest with the rear wheels through the windrow. The dump dozer [operator] saw the incident as it occurred, and attempted to stop the truck over the radio,” the regulator said.

Investigators believe mine designers should have more carefully considered dipping ground stability, wet conditions and material consistency.

“Inspections should verify the dump integrity. Areas that do not meet the standard should be demarcated, communicated and remediated to meet the standard,” the regulator said.
