Hi Brian
I sent my reply to subbrit list by mistake and have already had one reply as pasted in below. My
original email to you and the list that I sent to wrong place is further down still.
Cheers
Roger
"To confirm, the Hatfield Colliery, Thorne, ca. 10 miles N E of Doncaster, is the deepest coal mine,
and doesn't quite get down to 1,000m depth, http://www.minersadvice.co.uk/hatfieldmain.htm. The coal
seam dips down eastwards and was never mined east of here due to costs. Incidentally the reason why
Scunthorpe, some 20 miles further east, exists at all as a town,not the collection of small rural
hamlets it was in 1800, is that the iron ore around Scunthorpe, at a much shallower depth, some
surface-mined, was lean (poor in iron content), so it was cheaper to build the steelworks at source
and transport the coal east from Yorkshire, rather than transport poor grade ironstone west to the
coal source to smelt.
UK's mines of course dwarfed by South Africa at 3,900 metres,

Hi Brian
Possibly Boulby potash mine?? 1400m deep according to Wikipedia. This works out at 765.5 fathoms and
I think that depth was probably beyond most 'historic' mines pumping in 'old-fashioned' ways.
Yorkshire coal mines don't seem to go deeper than about 900 to 1000m as far as I can work out
(reference to coal seams at 1000m but probably not minde that deep.
South Wales coal mines are a lot shallower than 1400m, see
http://www.welshcoalmines.co.uk/forum/read.php?14,2654,13577
Llay main in Wrexham is claimed as the deepest in Wales and seems to have been worked to 905 yards
so a long way off 1.4Km.
Dolcoath mine in Cornwall was at a depth of 3500 feet (1067 m), for many years the deepest mine in
the world (again, I'm afraid from wikipedia!).
It would be good to hear the end result of your question on the list in due course.
Cheers
Roger

Hi All
Anybody have the depth of the deepest UK mine workings and the deepest shaft?
Cheers
Brian
