I find it ironic you criticize people of "lesser intellect" when it is patently obvious you have...what is the expression, round your way, "dogshit for brains". You get all your information from newspapers or television. You have a limited vocabulary, are incapable of secondary or tertiary logical reasoning, basically you are the living embodiment of Dunning-Krueger effect, like many pompous and intellectually vacuous Tories. You simply have no idea how stupid you are and that everyone around knows this to be true.
The decision to close the mines was one of pure spite. The issue as to whether the mines were unprofitable is irrelevant: farming for example has never been profitable and is still heavily subsidized. Manufacturing industry has been in almost permanent recession for decades. In that context it makes perfectly logical sense to subsidize coal indefinitely on the grounds of national security, since reliance on foreign energy is definitely a security risk, being a vital component of victory in WWII as farming was also.
But you know, feel free to come up with a counter-argument. But you won't, because, well, as we've established, you have dogshit for brains. So I can expect the usual two sentence dismissal borne of impotent rage and self-loathing, some comment about burners perhaps, some insults and some scoffing but nothing an eight-year old couldn't type. Knock yourself out.
