Two songs about actual mining disasters come to mind:

Ballad of Springhill (Ewan MacColl & Peggy Seeger)

Twelve men lay two miles from the pit shaft Twelve men lay in the dark and sang Long, hot days in the miner's tomb It was three feet high and a hundred long....

-and-

The Schofield Mine Disaster (Bruce Phillips)

When we gathered at the site We thought that just a few had died Fought our way in past the mine head carried out two hundred dead

When we brought them to the light It was a black and awful sight In one family there were nine lost within that burning mine

Can't you see that funeral train Oh can't you see that funeral train Rolling down that lonesome valley It's the longest one I've seen...

I can't sing either song without the imagery getting me teary-eyed.... Mike
