Available in PDF, EPUB and Kindle. Book excerpt: This paper, describing the mining practice at the Champion mine of the Copper Range Copper Mining Co., is one of a series of papers on mining methods and costs being prepared by the United States Bureau of Mines. Mining practice at the Champion mine has undergone considerable change during the last four years. Previous to that time the mine was worked by the horiztontal cut-and-fill method, the stopes starting near the shafts and advancing away from them (fig. 2. The floor pillars were mined by the inclined cut-and-fill method, working on the retreat or toward the shafts (fig. 1). At present the mine is being developed to stope entirely on the retreat by sublevel inclined cut-and-fill method.
