The disused Mir Diamond Mine in Russia's Eastern Siberia is 525 metres deep and 1.2 kilometres wide. There's restricted airspace above it because helicopters get sucked in by the enormous downdraft.It's the second biggest manmade hole in the world.
The world's biggest manmade hole is the Bingham Canyon Mine in Utah USA. It's 970 metres deep and 4 kilometres wide.
Four kilometres wide!
Because the Mir hole is empty and abandoned and as I dislike waste, I thought the hole would be a good choice to accommodate all the world's dysfunctional, untrustworthy, dictatorial, greedy, egotistical, self-serving, incompetent, did I mention stupid, bureaucrats and politicians if we were to drop them all in it.
But this hole may not big enough, perhaps the Bingham Mine would be better...
