Springhill Mine Disaster, Springhill, N.S., 1958

Springhill mining disaster may refer to any of three deadly Canadian mining disasters that occurred in 1891, 1956, and 1958 in different mines within the Springhill coalfield, near the town of Springhill in Cumberland County, Nova Scotia. In the 1891 accident, 125 died; in 1956, 39 were killed; and in 1958, 75 miners were killed. The mines in the Springhill coalfield were established in the 19th century, and by the early 1880s were being worked by the Cumberland Coal & Railway Company Ltd. and the Springhill & Parrsboro Coal & Railway Company Ltd. These entities merged in 1884 to form the Cumberland Railway & Coal Company Ltd., which its investors sold in 1910 to the industrial conglomerate Dominion Coal Company Ltd. (DOMCO). Following the third disaster in 1958, the operator Dominion Steel & Coal Corporation Ltd. (DOSCO), then a subsidiary of the A.V. Roe Canada Company Ltd., shut its mining operations in Springhill, and they were never reopened. As of 2015 the mine properties, among the deepest works in the world, with the No. 2 mine reaching 14,300 feet (4,400 m) and now filled with water, are owned by the government of Nova Scotia, and provide Springhill's industrial park with geothermal heating.
