Other Disasters Disasters
Springhill mining disaster may refer to any of three 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.
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 and filled with water, are owned by the government of Nova Scotia, and provide Springhill's industrial park with geothermal heating.
The 1958 bump, which occurred on October 23, 1958, was the most severe "bump" (underground seismic event) in North American mining history. The 1958 bump injured Springhill residents and devastated the town's economy.
Springhill's No. 2 colliery was one of the deepest coal mines in the world. Sloping shafts 14,200 feet (4,300 m) in length led to a vast labyrinth of galleries more than 4,000 feet (1,200 m) below the surface. Mining techniques there had been changed 20 years before the 1958 bump, from "room and pillar" to "long wall retreating" after reports had shown the increased danger of "bump" phenomena resulting from the former technique.
On October 23 a small bump occurred at 7:00 pm during the evening shift; it was ignored, as this was a somewhat common occurrence. However, just over an hour later, at 8:06 pm, an enormous bump "severely impacted the middle of the three walls that were being mined and the ends of the four levels nearest the walls". More details
