Two people have died in an underground mine explosion in Far Western New South Wales on Tuesday morning.

Emergency services were called to the mine on Endeavour Mine Road at Cobar, about 450km east of Broken Hill, about 3.45am, after being told two people had been critically injured in a workplace incident.

Police were immediately told one man had been confirmed dead after the underground explosion.

Two women were then brought to the surface, but one of them died shortly after.

The second woman was airlifted to hospital suffering hearing damage and shock.

At about 7.15am, police confirmed the deaths and said emergency services remained at the scene.

SafeWork NSW will lead an investigation into the incident, with police to also prepare a report for the coroner.
