摘要
本文分析了矿柱回采时爆破对两侧胶结充填体的各种破坏作用，提出了减小这些破坏作用的方案和措施，获得了运用高阶段大直径深孔采矿法回采矿柱的成功经验。
After the analysis of various damages caused by blasting to the cemeneted fill-mass on both sides during ore pillar mining,the authors advanced new blasting scheme and measures to minimize these damage actions and achieved successful experiences in ore pillar recovery with high block and large diameter long-hole stoping method.
