Castle Gate, Utah, mining disaster

Identification: The Event: A series of coal mine explosions that killed 172 people

Date: March 8, 1924

Place: Near Castle Gate, Utah

In terms of the number of people killed, the Castle Gate mine accident was the third worst mining disaster in the history of the United States at the time, and the second worst in Utah. All 171 men working in the mine, as well as one rescue worker, were killed.

Near the town of Castle Gate in Carbon County, Utah, about ninety miles southeast of Salt Lake City, the Utah Fuel Company operated Castle Gate Mine No. 2, one of three mines in the immediate area. Coal mining, then as now, was dangerous work; in the 1920s, most of the work was done by hand, and there were few safety regulations to protect miners. Just after eight o’clock on the morning of March 8, 1924, a miner noticed an accumulation of gas near the roof in the mine. As he inspected the area, his lamp blew out; when he struck a match to relight the lamp, there was a tremendous explosion, followed quickly by another one. Twenty minutes later, as people rushed to the scene, a third explosion occurred.

The force of the explosions was so great that the steel gates at the entrance to the mine were torn from their cement moorings and shot nearly a mile across the canyon, along with several poles holding up the tunnels. When recovery operations were finally completed, nine days after the explosions, it became clear that all 171 men working in the mine that morning had died. Another man died during the rescue attempt after inhaling the poisonous gases that filled the tunnels. Only about one-quarter of the victims were native-born Americans; the others were recent immigrants. Later investigations concluded that the explosions had been caused by inadequate damping of the coal dust present in the mine.

Impact

Despite the horror of the accident and the subsequent increase in workers’ calls to improve mine safety, little changed in the immediate aftermath. Public and governmental pressure encouraged mine owners to require rock dusting, the covering of coal dust with stone dust to reduce its flammability, but few complied. It was not until 1941, with the passage of Public Law 77–49, that Congress granted federal inspectors the right to inspect mines for safety violations.
