The document summarizes the 1909 Cherry Coal Mine disaster in northern Illinois that killed 259 miners. It provides background on the mine, owned by a Saint Paul mining company, which employed around 480 miners. On November 13, 1909, a fire started from a kerosene lamp attached to a mine cart and quickly spread. Rescue efforts were unable to save most of the miners trapped underground. The disaster revealed deficiencies in safety regulations, emergency planning and training. It led to new regulatory changes, including worker compensation laws and stricter fire codes, to prevent future mining accidents.
