Mr. Trump gushed about mining, telling the crowd that he was fascinated by it and promising to revive the industry. “You watch what happens: If I win, we’re going to bring those miners back,” he said. “You’re going to be so proud of your president.”This just isn't going to happen, for reasons I have laid out many times. Under Republican rule it might take a little longer for coal to be phased out and replaced by wind, solar, and natural gas power, but phased out it will be regardless. No new coal burning power plants are under construction or planned anywhere in the US, and that was true even before Obama's clean energy plan.
And even if it were feasible – which it isn't – would Trump have any idea how to do it? Probably not:
He did not explain how he would go about doing that.A sentence that perfectly exposes what Trump has been doing in his campaign.
