🚧 UNDERGROUND Comparison 🚧 (3D)

These are the DEEPEST underground STRUCTURES, represented on a real scale, mines, caves, cities, tunnels, installations, etc.

Note: Depth is measured from the lowest point to the surface, not to sea level.

I feel that the 3D effects on this are quite well done - the people walking around really helped gain the scale of the individual entries. Also - the music is a significant part of the reason I like these videos - this one did not disappoint; it seemed appropriately 'creepy'.

I find really fascinating that the "kilometers deep strange looking underground lab" isn't just science fiction

[shaun_rambaran]

The hand-dug well is insanely impressive!

[bruhmoment-jbwg]

There is something weirdly unnerving and both fascinating about the idea of these extremely scientific laboratories being stored hundreds to thousands of meters underground, the Kamioka Observatory especially fascinating me because it's like a huge cylinder underground.

My dad was an explosives expert with C.I.L. for years and was a consultant on how to place precision charges when building underground. He never liked going super deep underground. He didn't like the heat once you got really deep if they didn't ventilate the space well and he didn't like knowing that if anything went seriously wrong when you're a couple of miles underground you were probably really screwed and doomed to a horrible death. The escape procedures for deep mines and installations basically consist of providing shelter in place until someone comes down to get you, which isn't always possible.

Fortunately, catastrophic accidents are rare in deep facilities. Usually, it's individual workers who will get injured or killed rather than the whole place coming down. But it does happen. I found it interesting how people could have different fears. I mean my dad confidently worked with explosives every day that would have terrified most people but feared the underground. The difference was that his skill and other things under his control determined the results with the explosives but the deep dives into the Earth relied on others.

Thanks for these fascinating videos.

Appreciate the depth marker on the right, it helped keep reference when there was nothing else on screen.

Something interesting about kola superdeep borehole is that they discovered that at that depth rocks start to behave more like plastic. We may only guess what the consistency of the mantle must be like. The bore hole only reached as far as a third of way through the crust.

The neutrino laboratory in sudbury is part of Creighton mine and is one of the oldest mines in the area. Many cave ins there and awfully hot down at the 7000 ft level. They have a ice catch for keeping the mine cool during summer. My home town. We live down there for 12 hours a day.

They have a escape way, it would take 2.5 days to climb out.

Someone wanted to know where these places can be found so I did the hard work and put them here!
😄

Also thanks for the video!!! I love these videos a lot! 🤍
(Thank you everyone in the comment section, I have always smile on my face when I open this comment section up, digging the ground/internet has been my thing since childhood so this was super fun to do!)

Wow, 90% of those incredibly deep (or deeply below a mountain) locations I had never heard of before!

[haydenf]

The problem we run into when drilling super deep is the torque required to turn the drill string, the temperatures downhole and the pressures required to pump mud down the pipe and back up the annulus (to remove the rock being drilled). All of these mechanics have limits that modern equipment isn’t designed to exceed. Steel threaded pipe for example has finite torsional and tensile properties, not to mention the threads on each joint which could be a vulnerability especially if the hole isn’t truly vertical all the way down. Btw, there are holes drilled deeper than the borla but they’re drilled horizontally for the most part. When drilling laterally, the temperature aspect may be manageable but the pressure and torque/tensile limitations are more prevalent.

I've been down to a depth of a little over 2000 meters at the Mount Isa R62 mine (listed at 1900 meters but it's gone much further since that depth was official). Started working there are a timberman at the very bottom, installing/repairing poly pipe for water/compressed air, and vent bag for breathing air. Basically the stuff that people need to work, we went in without it and installed it. It's around 40-45 degrees Celsius and so incredibly humid.

I'm glad I worked there because I've explored somewhere 99% of people only see in movies. But I was also glad to get out when I got a job above at the smelter.

[DOSHIELD]

I always love the scale out at the end. Sooo cool. Excellent work MetaBallStudios

[moon_and_water]

I didn't know the large hedron collider was so deep! Awesome video as always

[dougmhd]

I've always been simultaneously fascinated and frightened by caves and underground human-made facilities. It also reminds me that, with all the (justified) attention given to outer-space exploration, we really don't know that much about the earth underneath our feet and the deepest ocean depths.

[bennnnnnnnsauls]

it’s amazing that all these things were built in relatively the same place, must have made it real easy for the cameraman

[topsecret]

The incredible part is that there might be caves at depths beyond anything we’ve built. But the super deep bore hole showed that at such depths the ground gets hot and begins to be incredibly difficult to move out of the way.

[Most-Weasel]

The video makes these tunnels and holes seem quite deep, but they have really only just scratched the surface of the Earth. Impressive feats nonetheless!

[manufacturedfear]

Love it! As an urban explorer, I've only been at -42m beneath the city surface, exploring a rainwater drain. This drain was so deep that at some points the subway tunnels passed above us.

[paulgibbon]

I just noticed the little trick at 2:13, where it introduces the oil wells on the right edge of the screen, to draw your eye there just as the scale appears. Nicely done!
