I'm not going to give away where this is on a public site as it took me ages to dig the mine entrance out enough that I could crawl in.
Initially I headed over to see the quarry and colliery but after walking around I noticed the top of a brick arch that was begging to be investigated.
After shifting a few rocks I could see in and it opened out right behind where it had been filled in, 30 minutes and a few rocks and slabs later and I had enough room to slide in :thumb
I wasn't expecting to head underground so I only had my headlamp and a torch on me :( so I didn't get many pics in the mine.
anyway on with the pics
The white coating on the walls glistened like it was metallic
I couldn't find any signs of these rocks falling from the roof or walls so I pressed on
After walking/stooping for 30 minutes I decided to head out until I had more light
I marked the spot with a lonely candle
I then decided to walk over to the colliery
This was as narrow as it looked but it gave access to the tower
