In a reported incident this week a dozer operating on a stockpile encountered a void that resulted in the dozer buried in a stockpile. The NSW Resources Regulator has confirmed that “While operating on a clean coal stockpile, a dozer sunk into a void. The operator was able to safely exit the machine.”
This is not the first instance of a dozer buried in a stockpile. The regulator has made a number of recommendations to the mining industry.
The hazard of concealed voids exists on stockpiles and must be included in risk assessments, training and procedures for operators. Operators must be trained in identifying when the risk is present and how to control this risk.
When designated equipment fitted with risk controls (in this case toughened glass and GPS) is swapped, the alternative machine must have controls to manage the risk to an equivalent level.
Three weeks ago in a separate mining incident, a dozer rolled on its side while working on a stockpile at a NSW mine. You can read the story here
