Mine Health and Safety Act of 1969 contained provisions for the training of Federal mine safety and health inspectors, as well as establishing education and training for states, mine operators, and miners. The Federal Mine Health and Safety Act of 1977 broadened these provisions to include metal and nonmetal mining.
Selective mining is a key feature. Here, Wirtgen surface miners successively remove up to 83 cm of the surface material in layers. Because the cutting depth can be adjusted and regulated precisely, even thin seams of valuable mineral can be extracted precisely from along the dividing layer with the dead rock (intermediate rock veins, i.e. unworkable …
