READ MORESafety and Hazards Dangers to miners. Coal mining is dangerous activity and the list of mining disasters is a long one. In the US alone, more than 100,000 coal miners were killed in accidents in the twentieth century, 90 percent of the fatalities occurring in the first half of the century. More than 3,200 died in 1907 alone. Open cut hazards are principally mine wall …
