They say that mining is getting safer-
From 1880 to 1910, mine explosions and other accidents claimed thousands of victims. The deadliest year in U.S. coal mining history was 1907, when 3,242 deaths occurred. That year, America's worst mine explosion ever killed 358 people near Monongah, WV.
While metal and nonmetal (non-coal) mining was less deadly than coal mining, available records for the era show that it, too, was highly hazardous. Fires, explosions and cave-ins caused many deaths and injuries. One of the deadliest non-coal mining accidents involved a mine fire in Montana that killed 163 men in 1917.
With each passing decade, the annual number of mining deaths and the even more significant rates of injuries (measuring numbers of injuries against hours worked) have declined.
Fatalities and Injuries for All Mining (Coal & Noncoal)

1936-1940 1,546 81,342
1941-1945 1,592 82,825
1946-1950 1,054 63,367

The death rate may be down, but the injury rate is still incredibly high. Mining is listed as one of the most dangerous jobs in the US by the U.S. Department of Labor.
