摘　　要：吴集铁矿-200 m中段以上一步骤采场基本回采完毕,正在进行充填,为了保证生产稳产衔接和积累二步骤矿柱回采经验,急需开展-200 m中段矿柱回采试验。结合赋存条件、矿柱特征,采用分段凿岩阶段空场嗣后充填法,顺利实现安全高效回采,为其他中段矿柱回采提供技术参考。The first step stope above the -200 m section in Wuji iron was finished basically,the filling work is conducted now.In order to ensure the production stable and accumulate the stoping experi-ence of the second step pillar,it is necessary to conduct the stoping test of -200 m section pillar.Com-bing with the occurrence conditions and pillar characteristics,the sublevel drilling open stoping in stage with subsequent filling method is adopted,therefore,the object of safety mining with high efficiency is re-alized,it can provide technical reference for stoping the other section pillars.
