A FEMALE contractor has been killed after a large dump truck and a four-wheel drive collided on an open cut mine in the Hunter Valley.

Emergency services spent nearly 12 hours at Glencore’s Ravensworth open-cut mine following the tragedy just before midnight on Saturday.

The woman was driving the four-wheel drive when it was involved in the incident with a 250 tonne dump truck.

Construction, Forestry, Mining and Electrical Union spokesman Peter Jordan said preliminary advice indicated the woman might not have given way at a haul road intersection.

A statement from the mine said the woman, an operator at the mine, died at the scene.

The truck driver was taken to Singleton Hospital suffering shock.

‘‘Our primary concern is for the safety, care and welfare of our employees and we are providing all possible support for the families of the people involved in the incident,’’ the statement said.

‘‘Staff working at the mine are also being offered counselling.’’

All operations at the mine have been shutdown.

NSW Minister for Resources, Chris Hartcher issued a statement on Sunday about the accident.

"I would like to personally extend my condolences to the families, co-workers and employers of those involved in this tragic accident," he said.

"An investigation is underway, with Police and three inspectors from NSW Trade & Investment’s Mine Safety Investigation Unit currently on-site. A full and detailed report will be prepared for the Coroner."
