Mining Australia has reported that investigations are underway after a roof collapsed at Illawarra Coal’s Dendrobium Mine in Mount Kembla yesterday.
In a statement, BHP Billiton subsidiary Illawarra Coal confirmed there had been a "localised roof fall in a roadway" at the site.
The mining magazine reported on its website that details of the collapse remained unclear, however a spokeswoman from Illawarra Coal said no-one was injured.
All 72 employees were evacuated and accounted for, she said.
Illawarra Coal president Troy McDonald said the priority at the time of the incident was to ensure that all employees were safe and he commended everyone for their efforts.
"At this time it is not anticipated that there will be interruption of supply of coal to customers," he said.
This is the third roof fall in four years at the Dendrobium underground coal mine.
