The “Seventh Five-Year Plan” of Liuguo Iron Mine is multifaceted in content. Only the core issue of its mining is analyzed and the resource strategy of developing Xuzhou Metallurgical Industry is discussed based on the conclusion of economic evaluation. 1. Overview of Liuguo Iron Mine Mining Planning 1.1 Reserves of existing mining areas: There are three mines in the ore mined area of Liuguo Iron Mine, West Mashan and Qiongli. By the beginning of 1986, a total of 13.23 million tons of iron ore deposits were stored, with good ore quality and an average iron content of 50-51%. Symbiotic elements such as copper, gold, silver and diamond were available. 1.2 existing mining area production capacity: the existing design capacity of the three mines 430,000 tons / year. During the “Seventh Five-Year” period, mills,
