The Eccles No. 5 mine was opened in 1905; served by the
Chesapeake and Ohio and the
Virginian Railway, it mined West Virginia smokeless coal. The mine was owned by the New River Colliers Company, a
Guggenheim family interest at the time. As with other West Virginia mines, the shafts pierced not only beds of coal but also pockets of
natural gas. Few coal faces at the time were lighted by electricity, and the miners lighted their work with helmets bearing
carbide lamps that burned calcium carbide to produce flammable
acetylene. About 2:30 p.m. on April 28, 1914, a series of massive explosions ripped through the mine. A later investigation indicated that the flame of a carbide lamp had touched off a pocket of coal gas, which in turn ignited other pockets. It was the second-worst mining disaster in West Virginia history (exceeded as of 2022 only by the
Monongah Mining Disaster). At least 180 men lay dead, this being the death roll published as of 2011 by the National Coal Heritage Trail. One of the men who died was an insurance agent from Charleston, West Virginia, who had gone into the mine just before the explosion to solicit business from the men. ==Labor union==
