The largest open cut mine in the world, Bingham Canyon, is more than ten times as deep.
While it's not a good idea to just chuck stuff into an abandoned mine, the effort to excavate a hole that size is doable for a single site operated by a single company employing 2000 workers over a century. It's pretty trivial in comparison to any other environmental problem.
- CoffeeOnWrite 2y ago> hole that size Bingham Canyon is roughly cone shaped, not comparable to the rectangular prism described above. To achieve comparable volume of the rectangular prism, you will need to dig a much deeper cone. https://www.mining-technology.com/features/feature-top-ten-deepest-open-pit-mines-world/ https://www.mining-technology.com/features/feature-top-ten-d...
- cm2012 2y agoQuick calc: An 1000 yard deep cone with 35 mile diameter has 3x as much volume as a rectangle shaped hole 100 yards deep with 35 miles on each side.
- CRConrad 2y ago> To achieve comparable volume of the rectangular prism, you will need to dig a much deeper cone. Yeah, holes with sloped sides are easier to dig than vertical-walled ones. But you don't need to have them sloping all the way down to a deep point in the middle; for a shallow (comparatively, like this) hole you can just slope the walls down to the same flat bottom. At a 45-degree angle, you could have the bottom of your 100-yard-deep pit be 35 miles - 100 yards across, and the opening 35 miles + 100 yards. Which would be a pretty negligible difference on the surface -- and, I think, make the volume a tiny bit bigger.
