The mining Authority have there web site which gives positions of the coal mines they know off, before around 1875 there are thousands they know nothing about. Then there are all the other types of mines, ganister, clay and Elland flags just to name my local ones.
You should do like the rest of us and start digging out old plans and Geology Plans.
There is a book for sale at the mining museum (Wakefield)which just gives the name of the mines the author knows off.
I would like to be given all the mines so I could publish it and I am sure 'Yorkshireman' would also.
'Yorkshireman's' Big Plan has taken a long time to build up and he is still adding names of mines we have found. There is also copyright problems. I have discussed this with him about selling copies, but without fully looking into this and possible liabilities I have not gone further.
Only this last week I have got my hands on another set of plans for above and below ground mine layouts round the Shuttle Eye Area.
