I've been wasting some time looking at boreholes and shaft cross sections, and just as an example At what was the Plumtree Collier, Nr Eastwood in Notts, sunk in 1851, the Top Hard seam was encountered at 98ft 7ins. In a BP borehole in Lincs it was at 736m.... That would put the bottom seams in that area at nearly 2000metres below the surface..
I'll post some boreholes with seam depths and locations later. Oddly, in some boreholes the Deep Soft, Deep Hard, Pipers and Tupton are missing, probably "washouts"..

Here's a colliery I've never come across in my research, not technically a colliery, the bore was driven in 1874.The bore is listed as "The Highfield Borehole" and was sunk to the north of the Clifton Colliery, between what would be it's workings and the Wollaton Colliery.... The name on the log is the Trent Colliery. Owned by the Hucknall No1 Colliery.
I wonder if they had the rights to the mineral reserves between the two pits??
Deep Soft 46.5 inches @ 559ft 1.5 inches.
Deep Hard 74 inches @ 615ft 11 inches.

Ruddington Borehole, this was drilled in 1966 to prove reserves for Clifton Colliery, very close the edge of the Permian Triassic, there's a line drawn on the abandonment plans showing the edge, which is a water bearing strata.
The upper most seams are missing, this was shown in an 1800's borehole near Ruddington, the topmost seams were "washed out.
Tupton 33ins @ 678ft.
3/4 21ins @ 690ft.

Looks like the NCB had extensive drilling carried out in Lincolnshire, bottoms seams were at or below 700 metres, pretty deep!!

When RJB took over in 95 they talked about sinking a new mine in Lincolnshire called I think witham or whitam. I don't know if it was all talk at the time, maybe it was in the long term plans of the coal board that RJB acquired?

I don't know if it was all talk at the time, maybe it was in the long term plans of the coal board that RJB acquired? "The Witham Prospect" was a potential under discussion and was envisioned as being around the Newark area and actually straddling the Notts / Lincs border. |

That could explain all the boreholes around that area.

Was`nt there a Thorne or Thorpe Pit,not far from that area,that was a total failure?

Wrong name Daz,but i`m thinking of the same area,
Not sure,but i think RJB closed this one,was to be a super pit.

If it wasn't Thorne then I've no idea Jim, sorry. Bilsthorpe Colliery was about 12 miles from Newark, a good old pit but not quite a super pit  |

I should have read your links Daz ,before replying,it does seem to be Thorne i was thinking about,there`s also a write up on the Welshcoalmines about Thorne,like your links,saying about the 1980`s developement,new headgear,also mention of a 3rd shaft started,but abandoned after the strike.
Did`nt realise Thorne was so close to the Humber,does`nt look that far from the Linc`s border either.

Thorne was the most easterly pit in Yorkshire to be sunk and I believe at the time of sinking it was the deepest at around 900m. Its not far from the boarder of North East Lincolnshire (What used to be South Humberside, don't know what it was before that!)I cant believe it was stood idle for over 40 years and what a waste after all the work that was done on shaft repairs, I don't know why they didn't just cap the shafts instead of filling them, I think I read somewhere there was 70 million tonnes of proven coal, plus loads more to the east and north into Snaith. I believe back in 86, I think around the time of the Margam project too that the coal board wanted to open both pits but use flexible working so the pits would work 7 days a week. The NUM was opposed to this so the projects never went ahead (so I remember from reading in Coal News). Just another excuse by the Governemnt/coal board I think!  |

Your correct there Wheldale regarding Margam,and the 7 day planned working,strongly fought against by the South Wales NUM,would have been better if they had negotiated shift patterns,no one would have had to work 7 days a week,and there Might have been a Pit started there,it was its best chance that`s been,and it was throwed away through pig headed ness.
Tata is the only hope for Margam,but its a strange affair,my butties and myself went to a talk in the Mining Engineers institute in Cardiff a few years back,well attended by all the big names in mining,and well presented,but what struck my butties and myself,also an ex NCB Surveyor,was the fact,that there was no profit margin in the project,there were several heads shaking.
The layout was perfect,2 drifts driven from Tata`s own compound,all muck coming out ,was to be taken to the old opencast site nearby for reclamation,but there was no noticable lagoons for water settlement,and water there will be in that area ,well documented about,
I cannot remember exactly,although there is a plan on the Welsh forum,the 2 drifts were to be driven on a 1 in 12 pitch for 2km,then pitch down into the seam on a 1 in 5,i believe for this was to drive over the water logged Newlands working,then dip down into the virgin coal,then drive another 2km while opening up the take.
Then it all turned into nonsense,knowing full well from all the NCB boreholes,other boundering Collieries plans,plus 10m spent on their own boreholes and seismic tests,it was stated that Only 2 target seams would be worked out of 6 if i remember correctly,and if they start,it will be 300m longwalls or nothing.
300million project,targeting only 2 seams,when they clearly don`t understand South Wales geology,and this area is one geologists nightmare,not forgetting the gassy area.

What was the objections to 7 day production Jim??
I worked at British Gypsum in the early 70's and they produced seven days a week, albeit Sat and Sundays were days shift production on overtime.
Then Boulby worked 24/7, only closed Christmas Day and Boxing Day. At the time I was there we had four shifts of mining crew and engineering staff. Worked three shifts spread over seven days, very odd shift pattern, but easily got used to.
Many a time on the way in on a Sunday Afternoon shift we talked of throwing our snap out the car window and having an afternoon down in Whitby, but we always ended up at work...LOL
