I cant remember much about it and it might not even be this one, its one of those where there's bits of brick vents above ground with crap thrown down, imagine a roc post type thing but 3x the size. There was a 5ft brick shaft like a chimney that had partly fallen down, a couple of metal tubes stuck out the floor in another spot and a caved in hatch/door with steps further across. It needed a little work to gain entry and I was there at night on a flying visit with little time.
But I must stress it may not be the same woods.
Someone else will surely clarify.
