Sounds like the Dunsil seam, at Clifton, it was set in the Bunter sandstone and it had a fireclay seam in the middle of the coal seam..Wasn't very thick though, about 20 to 25 inches from memory.
Around the Trowel area is where many of the middle coal measures outcrop. Not far from there was the Stanton Iron works just inside Derbyshire, which was built on the outcrop of what I think was the Deep Soft seam.
When they start that open cut mine, they will find a lot of old mineshafts plus a load of bell pits too, been mined since the 1500's that area.

I don't think the Dunsil seam has been worked around that area, if it is that seam that they intend working, I think most of the upper seams have been worked near the crop, plus not too far away is the old Cinderhill Colliery, not to be confused with Babbington!! Turkey Hill Colliery and a few others that worked some of the upper seams in the 19th century.
Closer to Strelley, Lord Newcastle had a couple of collieries, then the Middletons worked the original Wollaton Colliery, if you can call a large field of bell pits a colliery. Although they did have an underground mine in the 16th century.
There's been a lot of coal won in that area pre NCB days....
As you say, it would be funny if all they found was a load of pillars when they excavated the top soil etc...

There will be a number of seams to be opencasted, they can go down quite deep and recover coal from very thin seams. I have no idea which but what about the Waterloo group of seams.

Been looking at borehole records, and I'm wondering if there IS any coal to opencut!!!
A borehole the NCB sank at Shortwood in 1958 to prove the Tupton and Blackshale seams for Cossall Colliery in Derbyshire, shows a void of 7ft 0ins, and listed as the Deep Soft old workings @ 34ft 6ins. Then coal of 1ft 6ins @ 73ft 9 ins the it states old workings "fill" pit dirt and timber, sounds like an old pack.
This is supposed to be near where the open cut project is supposed to be!!
Then the next coal is 33inches @ 117ft 3 ins.
All seams to the north seem to get deeper. I'll spend a little time checking other bores around this area.

A borehole drilled in 1894 shows 8" of coal @ 18ft 5" then Deep Soft 6Ft 4" @ 68ft 3", then more old workings!! Deep Hard seam goaf 106ft 5" to 109ft 9"
Don't seem to be much coal left in the area..
Near by a bore named Trowell Moor Colliery, starts the bore at the Kilburn seam, 4ft 5 ins just below top soil. Then the next seam is the Naughton 8" @ 108 yds 1ft 10", then the 40 yard seam, 10" @ 121 yds 0ft 8", then the Alton Seam, 3ft 5" @ 153yds 2ft 3"...

The area they want to outcrop is not actual coal seams, the area has been mined and its all pit waste, mate owns much of the land and farms it, his father bought it from the NCB decades ago as pit tip land.
In nearby Ilkeston they built the Ilkeston bypass called Chalons Way which is a short, but straight road and when building it they found 58 unknown shafts, this was in addition to the 27 shafts they knew about, the whole area is littered with known mines and previously they have had 3 shaft collapses on this land alone which is 3 unknown shafts which made themselves known.
There are thousands of unknown shafts going back hundreds of years in the area as the area is full of geological faults and it is possible to hit a faulted area and run the seam to the boundaries of the mined area, but there is also a huge environmental risk as numerous toxic elements have been buried there over the centuries and not documented, land adjacent to the proposed mining area is already capped with clay as its too toxic to even treat as the technologies do not yet exist to deal with it. This could be an environmental disaster if it is mined and locals know this, hence the huge opposition. |
