Tyre explosion on rear dump truck following lightning strike

What happened?

A short but significant storm passed across a mine during day shift operations. Surface trucking operations were halted and operators were instructed to park machines. Personnel were transported to crib and office facilities until the storm passed.

Upon returning to the parking areas to resume operations, workers discovered the tyres (positions 3, 4 and 5) on a rear dump truck had exploded. The explosion caused tyre fragments to project into the general park up area and nearby mine road, and a rock ejector was found approximately 10 metres away from the machine.

How did it happen?

It is believed a lightning strike during the storm caused internal pyrolysis on the tyres leading to the explosions.
