BGS Site.

Great site if you want to know the depth of mines in the UK, seams their shafts went through, depth of seams at that location, plus you can find old collieries you never knew existed.

Thanks for that John - you're right, there's some fascinating stuff on there! I managed to find the sinking records for the pit that used to be a couple of hundred yards from our cottage, and that closed in 1895.

I found some interesting things from shaft sinking records too, as well as the great variance in seam thicknesses over a short distance.
