Working in coal mines, and working to support coal mines, aren't entirely the same thing. (More than) Half the country is against government provided healthcare, but that doesn't mean half the country works in private medicine or is immune to disease and injury.

Access to healthcare affects every single person and their community in a pretty obvious way. I don’t see any reason to assume people other than those in the coal industry and maybe their family and friends to care much about it. Maybe a few more for political ideology, but I still can’t see it being a significant amount.

The only reason we hear so much about it is because the states with coal industry hold some swing Senate and Electoral College votes.
