Yukon, West Virginia March 28, 1924 No. Killed - 26
(Bureau of Mines letters and Information Circular 6802 (15, P. 19))
The No. 2 mine, connected to the No. 1 workings, was in an isolated location. Three miners taking a short cut to their working places through unventilated abandoned workings set off gas with their open lights at 7:23 a.m.
Dust was stirred up, and a violent explosion spread over much of the mine. The mine was very dry and dusty although an attempt was made to water haulageways once or twice a day.
Of the 32 men in the mine, 26 were killed and 4 injured, and 2 escaped uninjured. Rescue and recovery crews, with some apparatus, removed the bodies and restored ventilation.
