After the successful rescue of the miners in Chile and some deaths in Ecuador and China, not to mention the Conchos catastrophe few years ago, it is worth having a look to George Orwell's Down the Mine (1937), a very accurate description of the work done by coal miners:
"(...) Watching coal-miners at work, you realize momentarily what different universes people inhabit. Down there where coal is dug is a sort of world apart which one can quite easily go through life without ever hearing about. Probably majority of people would even prefer not to hear about it. Yet it is the absolutely necessary counterpart of our world above. Practically everything we do, from eating an ice to crossing the Atlantic, and from baking a loaf to writing a novel, involves the use of coal, directly or indirectly. For all the arts of peace coal is needed; if war breaks out it is needed all the more. In time of revolution the miner must go on working or the revolution must stop, for revolution as much as reaction needs coal. Whatever may be happening on the surface, the hacking and shovelling have got to continue without a pause, or at any rate without pausing for more than a few weeks at the most. In order that Hitler may march the goose-step, that the Pope may denounce Bolshevism, that the cricket crowds may assemble at Lords, that the poets may scratch one another's backs, coal has got to be forthcoming. But on the whole we are not aware of it; we all know that we 'must have coal', but we seldom or never remember what coal-getting involves.
You and I and the editor of the Times Lit. Supp., and the poets and the Archbishop of Canterbury and Comrade X, author of Marxism for Infants--all of us really owe the comparative decency of our lives to poor drudges underground, blackened to the eyes, with their throats full of coal dust, driving their shovels forward with arms and belly muscles of steel".
