There's lots of other minerals that can be mined, using the same equipment, and skills Coal Miners have, and liberate resources for economic growth. These minerals exist in the same areas where coal is mined trading human lives for "Energy" and the promise of "Jobs." There's not a whole lot of specialty in Coal Mining that requires re-training to mine say Quartz, which isn't toxic to mine.
For Health, and Safety, coal mining needs to be automated as much as possible, because machines don't get blacklung.
Who wants to talk about Clean Coal?
