Did any of the pits working under the North Sea work longwalls??? Sounds a daft question, but dafter things have happened in mining...

Maybe, Seafield, Francis and Monkton Hall did.
Ellington, Easington, Monkwearmouth ??

Easington was certainly working long-wall faces in 1964 when I left. There were long-wall faces in Five quarter, Seven quarter and Low main seems. To me working under the sea was no different to working under the massive water bearing sand feeders which they had to freeze to reach the seams of coal. I don't know how they got away with it. They were working about 4 miles under the sea when I left.

I thought there we pits longwalling under the sea a few years back, just wasn't 100% sure.

Worked under the "Sherwood Sandstone" previously called the Bunter. In the Notts coalfield it was a source of drinking water for many towns and villages.

At Boulby, it held heavy brine at high pressure and was just 600 feet above the potash seam. I believe it did burst in on the south side long after I'd left. I have photos on a CD an old mate sent me of the area, bit of a mess when brine comes in to workings of evaporites!!!! ie potash and halites.

I knew there were plenty of Bord and Pillar workings under the North Sea.

What about Durham Pits, Dawdon, Wearmouth, Seaham, Vane Tempest, did they go under the sea?

Also Cumbria and possibly Point of Ayr in North Wales.

All the pits on the northeast coast worked under the sea.Most of them worked longwall.

We worked long-wall at Point of Ayr out under both the Irish Sea and Dee estuary.
