The notice was issued during an investigation and inspection on September 16 into the circumstances of an incident where an unoccupied light vehicle was reversed over by a dozer.
"During the inspection, alleged repeated breaches of mine procedures relating to the safe operation of light vehicles were identified by inspectors," the regulator said.
The inspectors considered the nature and prevalence of these breaches constituted a serious risk to the health and safety of workers and consequently a notice under section 195 of the Work Health Safety Act was served on the mine operator.
The prohibition notice remained in place until the mine has undertaken re-training of all workers and supervisors. Workers on each shift were retrained, with operations recommencing progressively.
A Whitehaven spokesman confirmed the Maules Creek mine is operating normally after it completed re-training of workers ordered by the NSW Resources Regulator.
