Presumably you have looked at 19th century maps of the area. They will usually give you a good idea of what you are dealing with, which will not be lode-back working in a coal mining area that is a feature of metalliferous mining. Why do you think that it may be a 19th century mine could it not be much earlier? It is very difficult to distinguish an early 19th century shaft from a 17th century one without the help of documentation. The pile of slag you mention, is it really slag i.e metal working residue or is it mine spoil?
