I was looking at some of the borehole logs from Lincs over the weekend.
The seams are pretty deep by anyone's standards, one bore went down to 5594ft and it measured 160F at the bottom!! Barnsley bed was at 4418ft and was 48" thick. Lower measures went down to 5087ft.
In another one near Hemswell Cliff the coal measures started at 3900ft.
At Walkeringham in Notts, Top Hard was 3107ft 5ft thick, Deep Soft was 3530ft and an incredible 1ft 6" thick, Parkgate was at 3620ft and was 3ft 9", Low Silkstone 3845ft and 1ft thick.
Another bore near Newark, coal measures started at 1375ft and ended at the Millstone Grit at 1970ft.
I found some oil exploration bores half way across Lincolnshire with seams far deeper, some nearly on par with CPL's Boulby Potash Mine.!!!
There's no wonder the NCB never bothered sinking any collieries that far east.
