An alternative transport route had been set up and communicated to the workforce. While driving into the mine the driver drove through a swilly, putting muddy water on the windscreen and lights.

He did not see the no-road tape and subsequently drove through it. The transport then collided with the roof support.

“Mines should consider barricading standards (for example jersey barriers) or signage (for example flashing lights) for use on main transport roads when the road is obstructed,” Mine Safety said.

“All vehicle operators should be reminded to keep their machine fit for purpose during use - clean windscreen and clean lights were an issue in this case.”

In another incident, contact was made between an LHD canopy and an 11KV cable, tripping the electrical protection. The machine was shunting to allow an oncoming vehicle to pass and was raised up as it ran over rib spoil.

“Where a cut-through contains high voltage transformers, belt starters and other major electrical plant – mine systems should provide for demarcation barriers to be installed and maintained to a standard that restricts vehicle access and protects electrical cabling and equipment,” Mine Safety said.
