Some of those giant earth-movers, like the tracked mining equipment that fills a giant mining-sized dump truck, are already powered by electricity that is generated on-site. They have big giant cables that trail behind them.
I mention this just to share that there is some chance of this improving, even in areas we might not think likely. If it is a long-term mining operation (short-term someday, perhaps) then I can't think of a technical reason that prevents wind and solar being used to generate the on-site electricity.
A recent HN article was about one of the mining dump trucks being powered by battery and using regenerative braking to mean it was able to charge itself. Those giant diggers are already using braking in their cables that power their shovels. Maybe there is something to capture there, as well.
In my work, I had the chance to deal with some riggers and some crane operators (smaller stuff) by just exposure while collecting data. During that exposure, I learned something new. Lifting the stuff up is actually pretty easy. It is putting it down that is difficult. Maybe there is some energy to capture in that process?
