IC 6811 Safety in Mining

Although it is impossible to give definite final figures at this time on Nation-wide accident occurrence in 1933 , enough data are at hand to indicate that the progress in safety in the mining industry, which first became apparent in 1930 and was accentuated in 1931 and 1932 , was continued and much improved in 1933. This improvement was of considerable magnitude in mining both bituminous coal and anthracite but was not so great in other branches of the mining industry . While the volume of work done in all phases of mining increased in 1933 over that in 1932 , the exact amount of the increase is not yet known . Usually increased activity in mining is accompanied by even greater increase in the rate of occurrence of accidents to the workers , but happily it appears that this " rule " was not operating in 1933 --at least in the coal -mining industry .
