From page 19... ... RESIDUAL DEMANDS FOR UNDERGROUND EXCAVATION Despite the fact that the cunent rate of technological improvement in underground excavation is insufficient to reduce the national concern over environmental quality, there are fairly well-defined and sizable future demands for underground excavation, even if these demands are only those for which no conceivable surface alternative is available. From the economist's standpoint, excavation is an intermediate good, and the amount of excavation demanded is dependent on the demands for other goods, particularly the demands for construction and for mineral industry outputs.

Unfortunately, the RFF report contains no forecasts of domestic production, but with a certain amount of loose comparison of the demand data in Tables 2 and 3, it is not too unreasonable to assume that the domestic production values given in Table 2 roughly translate into the amount of domestic mining in the decades 1970-1979 and 1980-1989 shown in Table 4.
