|Monongahela Mine Explosion
December 6, 1907
Nearly 400 workers were killed today when a coal mine exploded at Monongah, West Virginia. Methane gas ignited in the mine which then burned coal dust. The accident happened in Monongahela mines Nos. 6 and 8 and was caused by the fan house, which supplied the miners with air, failing to work. There were some very marvelous escapes, several men having been blown out of the mines through the air holes and escaped with only a few slight injuries. The explosions caused the earth to rumble as far as eight miles from the mines, shattering pavement and disrupting streetcars from their tracks.
