Two men have died in a mine collapse in the NSW Hunter Valley.
The pair were two of eight miners working 500 metres below the surface at the Austar Coal Mine in Paxton, about 10km south of Cessnock, when a wall collapsed at about 9.15pm on Tuesday.
Emergency services were summoned to the coal mine, located on Middle Road in Paxton.
A rescue mission was launched, but both were pronounced dead three hours later.
Police said one man was a 35-year-old from Metford, and the other a 49-year-old from Cessnock.
A crime scene has been established and will be examined by specialist forensic officers.
All mining production has been stopped at the site while investigations continue.
