摘　　要：获各琦铜矿2009年前主要采用浅孔留矿法进行回采,由于矿岩破碎,矿房在采矿或大量放矿时发生不同程度的垮塌,造成三柱回收困难、安全性差、损失贫化高。2010年矿山对采矿方法进行优化,通过4年的不断总结和改进,积累了一定的经验。本文重点对改进后的采切工程布置进行总结,为其它矿山回采类似矿体提供借鉴。The short-hole shrinkage method was mainly used in Huogeqi Copper Mine before the year 2009. The mine stope collapse often happened during mining and mass drawing because of the fractured ore rock, and it caused the pillars recovery difficulty, the poor safety,and the high loss and dilution rate. Mining method was optimized in the year 2010, and some experience was accumulated through four years production and improvement. In this paper the layout of preparation and cut engineering after mining method improvement was summarized, which provided reference for other mines in similar mining condition.
