Today is the 50th anniversary of the third Springhill coal mine disaster.
The CBC has some archival TV footage from the days following the disaster. Seventy four men were killed in the disaster, and 100 miners were trapped underground for almost nine days before being freed.
Prior to the deadly events of 1958, there were two large mine disasters at Nova Scotia's Springhill Mine, one in 1956, and another in 1891.
