A fair portion of their huge equipment is already connected to a power cord, so electricification isn't a problem itself. But pretty much everything is moving 24/7. For things like heavy shovels uptimes are commonly 88% per year. When you look at how much maintenance is needed to keep running in these rough environments it's a pretty amazing number.

Please see my sibling comment.
Do we really use 2000A cables running around a work site? Are they buried ?

Yep, and no mostly not buried. They have cable tractors to move around the wires and heavy spools. At the interface they'll have it lifted in places so the trucks don't drive over it.
