Nov. 20, 1968: Farmington Mine Explosion Kills 78
In the predawn hours of November 20, 1968, a massive explosion ripped through the Consolidation Coal Company’s Number 9 mine near Farmington. Twenty-one miners were able to escape. But another 78 were trapped inside. At first, the intense heat from the fire kept rescuers out of the mine. When they finally got inside, the mine was unstable, and officials feared another explosion. After nine days, the mine was sealed as a safety precaution with all 78 miners still inside.
