This subreddit is a place for those interested in abandoned mines and other various disused tunnels and underground facilities. Please follow all rules for both the sub and the website in general.

 

Other subs you might like:

Rules:

  • Posts must talk about abandoned underground facilities, posts about tunnels or mines still in use have a home elsewhere.

  • Reposts don't warrant a ban but spam does.

  • All reddit rules apply, and abusive behaviour will result in a permanent ban.

  • Absolutely no location specifics in the post or the comments, only by PM. This rule is for the preservation of the location, and the safety of those without the experience to explore safely.

 

If you think this sub can be made better, or would like to become a mod and help keep it running, message /u/Dragonborn1995 or /u/ChewyUbleck.

 

Entering abandoned mines is not recommended.

 

Remember that these places are old and can be extremely dangerous. For this reason only those with the proper gear and experience should enter an abandoned mine or tunnel. Read more in the link below:

If you do decide to visit an abandoned mine, please respect the site itself as well as the property owner (if applicable).

 

Take nothing but pictures, leave nothing but footprints. Last of all, have fun, don't be an ass, and be safe!

New video up, and the start of a 3 part series where we seek out the Blacksmith's Shop, deep underground in an abandoned Ironstone mine that has hundreds of miles of tunnels. We also often come across dangerously bad air, and seek the remains of the furnace that provided fresh air to the complex :

Radon.

Hello! I've been actively exploring abandoned gold/silver mines for a few years in my local area, however, I've just recently found out about radon and how it accumulates in unventilated adits. Do you guys think that abandoned gold mines from 18th century that are somewhat ventilated have okay-ish levels of radon? Should I be worried about radon when exploring? Do you take any safety precautions regarding radon? Thanks!

A Dam in a Mine

I can't remember which mine this was, but it was very wet and a few dams holding back columns of perfectly still water.

Inside an old fluoride mine.

Found an entrance via a manhole cover to take a look inside. I didn't went very far inside, but I will probably post an update this weekend.
