Two miners trapped in Kellingley, north Yorkshire, A rescue operation is under way to reach two miners trapped underground in North Yorkshire, the National Union of Mineworkers said.

The union said the men are trapped up their waist by debris after a roof fall at Kellingley Colliery, close to Knottingley.

They are said to be some distance from the entrance shaft. An air ambulance was deployed at about 17:00 BST.

Managed by UK Coal, it is one of Britain's deepest remaining mines.

The two main shafts are 800m (2624ft) deep and employs about 600 staff.

Rock fall
On 30 November 2010, 200 workers were evacuated from the pit after a methane explosion underground.

Miner Ian Cameron died after equipment fell on him on 18 October 2009.

In September 2008, Don Cook died in a rock fall.

Kellingley supplies coal to local power stations and produces some coal for households.

Earlier this month, four men were killed in a Swansea Valley colliery in Wales.
