A dump truck reversed to a dump windrow on an active tip head to tip a load of waste. The windrow collapsed behind the rear tyres with the truck’s tyres going through the windrow.
Recommendations to industry: Mine operators should review how workers are trained and assessed in recognising when a critical control is not in place or to the correct standard, such as windrow design. Mine operators should review how their supervisors monitor critical controls and actions to be taken where critical controls are identified as being inadequate.
