“231 MINE WORKERS KILLED” reads the headline of this November 1, 1988 issue of the United Mine Workers Journal, which shows one of the twelve miners miraculously rescued after being entombed for six days following the mine disaster in Springhill, Nova Scotia on October 23 that took 88 lives. It is the subject of a recent book, “Last Man Out,” by Melissa Fay Greene, published in 2003 by Harcourt, Brace. All told, during the 20th century, there were 582 mining disaster incidents involving five or more persons, and a total of 12,797 fatalities.
