Mining accidents

From 1880 to 1910, mine accidents claimed thousands of fatalities, with more than 3,000 in 1907 alone. Where annual mining deaths had numbered more than 1,000 a year during the early part of the 20th century, they decreased to an average of about 500 during the late 1950s, and to 93 during the 1990s. In addition to deaths, many thousands more are injured (an average of 21,351 injuries per year between 1991 and 1999), but overall there has been a downward trend of deaths and injuries. The
