摘　　要：某铁矿因采矿方法效率低,矿山生产能力一直没有达到设计要求。通过对矿山开采技术条件的调查研究,优化选择大直径深孔阶段空场采矿法进行试验回采,一年多的现场工业试验结果表明,矿山生产能力由4000t/d提高到7000t/d,既增加了产能,又降低了生产成本,为矿山相似产状部位矿体回采提供了技术支撑。Due to the low efficiency of mining in an iron mine, the production capacity has not met the designed requirements. Through investigation on the technical conditions of mining, the large-diameter and long-hole subsequent openstope mining method was optimally taken for test. The industrial test results over one year proved that the mining capacity was increased from 4000 t/d to 7000 t/d. The method not only increased the production capacity, but also reduced the mining cost, which provided technical support for the mining of similar ore bodies.
