With the news of yesterday's mine accident in West Virginia, the US has now seen a total of three serious mine accidents in just a few short weeks.  The news dispatches from these grim scenes are reminiscent of the harsh reality chronicled by George Orwell in his 1937 book, The Road to Wigan Pier:

It is not long since conditions in the mines were worse than they are now. There are still living a few very old women who in their youth have worked underground, with the harness round their waists, and a chain that passed between their legs, crawling on all fours and dragging tubs of coal. They used to go on doing this even when they were pregnant. And even now, if coal could not be produced without pregnant women dragging it to and fro, I fancy we should let them do it rather than deprive ourselves of coal. But—most of the time, of course, we should prefer to forget that they were doing it. It is so with all types of manual work; it keeps us alive, and we are oblivious of its existence. More than anyone else, perhaps, the miner can stand as the type of the manual worker, not only because his work is so exaggeratedly awful, but also because it is so vitally necessary and yet so remote from our experience, so invisible, as it were, that we are capable of forgetting it as we forget the blood in our veins. In a way it is even humiliating to watch coal-miners working. It raises in you a momentary doubt about your own status as an ‘intellectual’ and a superior person generally. For it is brought home to you, at least while you are watching, that it is only because miners sweat their guts out that superior persons can remain superior.
