摘　　要：地下金属矿山矿房底部出矿结构设计是采矿工程设计中的重要环节。某地下铜矿矿柱回采阶段高度由100m段高调整为50m段高,若仍按照原堑沟底部结构进行设计,将造成采切工程量增加、采切成本增加、生产效率降低等问题,本文通过对底部结构进行优化,将原堑沟形式优化为平底结构,并从生产效率、安全、经济三方面进行了对比,结果表明优化后的底部结构不仅提高了采矿效率,降低了生产成本,还使得出矿安全性得到了提升,所提出的平底结构也可为类似段高调整的矿山提供参考,具有一定的借鉴意义。For underground metal mine,the stope bottom structure design is an important part of the whole mining activities.In order to mine out an underground copper mine pillar,the height is optimized from original 100m to current 50m.If it is still designed according to the bottom structure of the original trench,it will cause an increase in the amount of developing and cutting,an increase in financial cost,and a decrease in production efficiency,etc.The proposed flat bottom structure compared from original trench form at the aspects of production efficiency,safety and economy showing that the optimized one not only improves mining efficiency,reduces financial cost,but also improves mine safety.The pillar excavation proposal provides some significance reference for mines which are facing the same situations.
