Mar. 14 -- There are deeper mines in North America than the Resolution mine but none with a single shaft this long. It is a 6,943 foot concrete barrel, 30 feet in diameter bored into the mountain of Arizona and took six years to dig. Bloomberg's Matt Philips journeys toward the center of the earth to check out this engineering marvel. (video by Adam Wolffbrandt)
why the fuck wont you idiot americans adopt the metric system. ie 0 degrees celicus water freezes 100 it boils. makes life a lot fucking easier. Makes you sound fucking stupid when you say its 100 degrees outside.
Macassa mine in Kirkland lake Ontario was 7325 feet deep And was at one time the deepest single lift shaft in the western hemisphere . Creiton mine in Sudbury Ontario.over 7000 ft deep. Kidd creak mine in Tiimmins Ontario is the deepest base metal mine in the world almost 3000 metres.
What they don't say is the surface drops into the hole all the beautiful desert is going to look like a big pit all the animals that live on the surface will be killed and jeep trails which we have been using for years will be closed off.
You do realize, that because the vast majority of overburden is extremely competent sandstone, that subsidence will be extremely minimal. If there's any at all. Your desert and jeep trails will be fine.
I grew up practically next to that mine and method there planning to use is called block cave mining it really is bad idea, the rock down there is so tough that when try try this they're gonna get boulders the size of houses, and I know for sure no one is gonna be willing to unjam it
