The Scotia Mine was a coal mine that operated in the community of Oven Fork in Letcher County, Kentucky. The mine began operations in 1962, as a subsidiary of the Blue Diamond Coal Company. In March 1976, two explosions occurred within the mine, killing 26 miners. The explosions led to the passage of several acts relating to safety in coal mines.[1]
The Scotia Mine was originally opened into the Imboden coalbed.[2] In 1975, an additional opening in the form of a concrete lined 13+1⁄2 foot diameter shaft, 376 feet deep. The lining of the shaft was completed July 21, 1975, and work was begun to install an automatic elevator. On March 9, 1976, the construction had not yet been completed and the shaft was being used only as an intake air opening.[2] Of 310 employees, 275 worked underground on two coal producing shifts and one maintenance shift per day, 5 days a week. Approximately 2,500 tons of coal were produced daily on six active sections, consisting of five continuous mining sections and one conventional mining section.[2]
The last federal inspection of the Scotia Mine was completed on February 27, 1976. On March 8, 1976, on the evening shift, a Federal Coal Mine Inspector conducted a Health and Safety Technical Inspection.[2]
Scotia Mine Disaster of 1976
On March 9, 1976, at approximately 11:45 a.m., an explosion caused by coal dust and gasses rocked the Scotia Mine. Two days later, a twin explosion occurred. The first explosion killed fifteen miners; the second killed eleven. Investigators believed that both explosions were caused by methane gasses ignited by a spark in a battery-powered locomotive or another electric device. A lack of ventilation also contributed to the accidents.[1][3]
