Fraterville Mine disaster

The Fraterville Mine disaster was a coal mine explosion that occurred on May 19, 1902 near the community of Fraterville, in the U.S. state of Tennessee. Official records state that 216 miners died as a result of the explosion, from either its initial blast or from the after-effects, making it the worst mining disaster in the United States' history, and remains the worst disaster in the history of Tennessee. However, locals claim that the true number of deaths is greater than this because many miners were unregistered and multiple bodies were not identified. The cause of the explosion (although never fully determined) was likely ignition of methane gas which had built up after leaking from an adjacent unventilated mine.

Shortly after the disaster, the bodies of 89 of the 216 miners killed in the explosion were buried in what became known as the Fraterville Miners' Circle at Leach Cemetery in the nearby town of Coal Creek (modern Rocky Top). In 2005, this circle was placed on the U.S. National Register of Historic Places.
