An excavator was excavating blasted waste material at an open cut coal mine during night shift when an unplanned initiation of explosives occurred.
Multiple pieces of flyrock hit the windscreen and body of the excavator, damaging the windscreen. The operator’s cabin was not breached.
Flyrock was scattered up to 63 metres from the dig face, damaging a side mirror of a truck being loaded and hitting a dozer that was cleaning the floor at the time of the incident.
The operator was not injured but this incident had the potential to cause serious injuries to the excavator operator and highlights that large amounts of energy are released when explosives are initiated.
Investigations are continuing into this incident.
