摘　　要：在康家湾开展顶底柱残矿回采已有十多年的历史,积累了丰富的经验,总结提出了顶底柱残矿进行回采的临时支护配合间隔式进路回采方法。通过十多年的实践,回采出20余万t高品位顶底柱残富矿,取得了良好的效果,证明该种施工方法和工艺流程非常适用顶底柱残矿安全高效回采。分析总结该施工方法的支护参数和施工工艺,对国内使用充填采矿法的矿山安全回采顶底柱残矿具有重要的作用和意义。The history of stoping residual ore of the roof and bottom pillar in Kangjiawan has more than 10 years, so rich experience in practice is accumulated. It summarized and proposed a interchanging tunnel mining method with temporary support for stoping residual ore of the roof and bottom pillar. 20 million tons of residual ore of the roof and bottom pillar with high grade has been extracted through many years of practice, and it had got good effects. The construction method and technological process are very applicable to stoping residual ore of the roof and bottom pillar in safety and high efficiency. This paper summarized support parameters and technological process of this construction method, and it plays an important role in the use of stoping residual ore of the roof and bottom pillar with back-filling method for domestic mines.
