摘　　要：浅孔留矿法是我国金属矿山目前采用的主要采矿方法.本文通过在得耳布尔铅锌矿的探索试验,针对传统浅孔留矿法在生产实际中存在的问题,对底部结构进行了改进,提出了无底柱平底结构装岩机出矿浅孔留矿采矿法,并成功地应用到生产实践中,取得了较好的效果,其探索思路对类似矿山具有借鉴意义.Short-hole shrinkage stoping is a common mining method adopted in metal mines in China. Based on the practice of this method in Derbur lead-zinc mine, Inner Mongolia, with analysis on the problems of the traditional short-hole shrinkage mining in production, this paper improves the bottom structure and puts forward a short-hole shrinkage method with non-pillar fiat-bottom structured rock loader. This method has been successfully applied in pro- duction with satisfying effect. Such an idea and practice is significant for similar mines as reference.
