Methods, Costs, and Safety in Stripping and Mining Coal, Copper Ore, Iron Ore, Bauxite, and Pebble Phosphate

Description: From Extent of Open-Pit Mining and Purpose of this Publication: "Various methods and machines are employed, and costs are low; in fact, costs have to be low because coal and ores command a low price on the market. These factors, together with queries on methods and costs of stripping and the increase in open-pit mining, have justified investigation by the Bureau of Mines for this form of mining and publication of the results in this report."
