摘　　要：大冶铁矿将崩落转充填开采的过渡区作为充填法试验矿块,根据矿山原有开拓系统的布置,将充填试验矿块从21#～34#进路划分矿房矿柱,采用浅孔留矿嗣后胶结充填法回收矿石,可有效提高矿石回收率,降低贫化率,实现崩落法向充填法的提前过渡,对于培养工程技术人员、调试充填系统有重要意义.同时,通过对大冶铁矿全尾砂物理性质进行分析,计算得到其充填倍线为5.9,可实现自流输送.The transition zone from sublevel caving to backfilling method was taken as backfilling test nuggets in Daye Iron Mine. According to the original arrangement of development system, ore block of backfilling test was divided into rooms and pillars from 21# to 34# drift using short-hole shrinkage backfilling method to recovery the ore body, which could improve ore recovery and reduce dilution rate effectively. At the same time, the early transition of mining method also had important implications in both engineering and technical personnel training and debugging filling system. Through the experimental analysis of Tailings＇ physical properties in Daye Iron Mine, the stowing gradient is 5.9, which could achieve gravity flow.
