2,262 meters equals 7,241.26 feet, not 40,230 feet as stated in the posting. Perhaps they meant 12,262 meters, which would be closer.

Appears to still be a place of great national pride.....

At least they capped it so they will not have to dig a 40K foot parallel shaft to rescue some small child.

I wonder how much pipe and casing is still in the ground there?

Probably about 3 feet, just enough to keep the cap stable.
