With an estimated 16 billion tons of mineable coal available and an annual output of some 127 million tons--a fourfold increase in 20 years--in 1966 Poland ranked fourth in Europe and seventh in the world as a coal supplier. New mining methods, new mining machinery, comparisons of production and efficiency attained underground, new trends and applications for the future, safety programs, and the special status of the Polish miner are all discussed and illustrated"--Abstract, p. i.
