Apparently the largest electric mining trucks on earth never have to charge. They go up the hill empty, load up with tons of rock, and regen all the way back down which is more than enough to recharge. This makes my engineer's heart smile.
I realize there are differnt kinds of mines, but assuming it's a hole in the ground, the truck takes the material up, and the hole isn't situated on a hill... why and where is it going down with material? Really interested to read about this.

It was a particular scenario where the quarry was uphill from a factory. Most mines and quarries probably don't have that possibility (They are both holes).
Well that can't be true.
Think it through a bit more, there isn't any physics being broken here, because the load (i.e. mass) only travels one way.
