The underground extent of Ifton Mine

I've taken the diagram from the previous picture, from NCB plan 1966, and drawn it onto a modern map. I've also marked where the exploratory drill for CBM is planned in Dudleston.

I hadn't realised until today how far east and north east the old workings extended. The plans are amazingly detailed, with roads, walls, faults and where the water drains to all marked.
