This Bureau of Mines study estimates typical capital investments, operating costs, and selling prices for two bituminous coal strip mines in the eastern and interior provinces and a subbituminous coal operation in the northern great plains province. The annual productions were based on tonnage required to fuel a 250-mm-scfd, high-btu gas plant. The annual tonnage for the eastern province mine is 4.8 million tons; for the interior province mine, 6.72 million tons; and for the northern great plains province mine, 9.2 million tons. It is assumed that the mines have a 20-year life. These studies are considered typical for the areas involved. Costs will vary depending on specific locations in these areas.
