“…The decision to open a mine and the scale of that mine critically depend on the site geology.6 By appropriate choice of homothetic transformation, it is possible to model another significant phenomenon in strip mining, capacity constraints that arise from the mine site geology. Baker (1979) and Malhotra (1975).…”

Abstract--Increasing returns to scale (RTS) is frequently postulated as affecting productivity in surface coal mining. However, it is not clear whether increased capital intensity or increased output is the relevant phenomenon. A ray-homothetic production function that incorporates the capital-labor mix and fixed site geology into the scale elasticity is presented and estimated with a micro (mine level) dataset. The results indicate that higher capital intensity contributes to higher RTS for some types of capital equipment, but not all. On the average increasing RTS was found, with few mines approaching optimal scale.

The purpose of this article is to investigate the causes of labor productivity decline in bituminous deep mines during the 1970s. Prior to 1970, coal mining was a leading industry in productivity growth: average deep mine labor productivity increased from 5.8 tons per miner per shift in 1950 to 15.6 tons per miner per shift in 1969. Since 1969, average labor productivity has fallen every year to a 1977 level of 8.7 tons per miner per shift.

Our paper analyzes the sources of labor productivity variation in U.S. bituminous coal surface mining from 1960 to 1976. The coal mining industry was among the first to experience a prolonged decline in labor productivity in the post-World War II period. In surface mining nationally, labor productivity in 1977 was 26.6 tons per worker-day, or 28 percent less than the peak of 36.7 tons per worker-day achieved in 1973. Moreover, in several major coal-producing states, the decline began much earlier and was more dramatic. For example, in West Virginia (the first state to experience declining productivity) the loss in productivity between 1965, the year in which productivity in the state peaked, and 1976 was nearly 52 percent. Eastern Kentucky experienced an even larger drop of 56 percent between 1967 and 1976. It was only the expansion of surface mining to western states in the 1970s that delayed the appearance of a national decline in productivity until the early 1970s. The industry has thus foreshadowed the labor productivity declines that subsequently occurred in other industries.
