宣钢近北庄铁矿是国家八五期间重点建设矿山,二期扩建后将成为宣钢主要的矿石来源基地。为满足二期扩建深部开采的需要,受宣化钢铁公司委托,冶金部勘察研究总院为技术负责单位,与冶金部马鞍山矿山研究院和宣化钢铁公司近北庄铁矿基建工程指挥部共同完成近北庄铁矿深部开采边坡稳定性研究任务。该项研究始于1991年4月,终于1992年12月。冶金部建设司于1993年4月12日至13日对该项科研成果组织了鉴定。与会专家一致认为:
Nearly Beizhuang Iron Mine is the key construction mine during the period of the Eighth Five-Year Plan of China. The second phase of expansion will become the main ore source base for Xuanhua. In order to meet the needs of the second phase of the expansion of deep mining, commissioned by Xuanhua Iron and Steel Company, Metallurgical Exploration and Research Institute of Technology as the unit responsible for the Ministry of Metallurgical Mining Research Institute and Ma On Shan Coal Mine near Xuanbei Iron & Iron ore deep mining slope stability research mission. The study began in April 1991 and finally in December 1992. Ministry of Metallurgical Construction Division in April 12, 1993 to 13 on the scientific research organization organized appraisal. Experts agreed that:
