Some of that in the article you linked to is just media bias against Coal, and some of it is speculation, but there is no question Coal mining will get a huge boost under the Trump administration which not coincidentally could be planning to use it as U.S. leverage in renewed trade negotiations with Foreign nations in need of an abundant, reliable, & cheap energy source.
At any rate, it's better than pronouncing the entire industry "dead" as would have occurred under another Clinton administration.
