摘　　要：留矿法是空场采矿法的一种，空场采矿法具有工艺简单、成本低、劳动生产率高等突出优点。目前国内外都在重视空场采矿法的研究与发展。据不完全统计，国外金属矿采用空场采矿法占地下总出矿量的６０％，我国金属矿山对空场法的研究也在不断地发展，已应用空场采矿法的锰矿山就有铜锣井、龙头、宁强、屈家山、斗南、鹤庆等，其产量有可能增长到占地下开采锰矿总产量的５０％以上。本文通过国内外实例介绍空场法留矿采矿法的技术进展。The shrinkage method is a kind of the open-stope method, Which has many obvi-ous advantages, Such as, simple technology, low cost and high labour productivity , etc. So it ispaid much attention to at home and abroad.According to incomplate statistics, about 60%of to-tal output from underground mining are got with the method of shrinkage mining in metallicmines of foreign countries.Great progress has also been made in the study of this method inChina. Some manganese mines,such as Tong Luojin, Long Tou, Ning Qiang,Qu Jiashan,Dounan, He Qing etc,have used it in practic. The output Will increase probably more than 50%of the totel output of underground manganese mines. This paper described the technical progress ofthe open-stope shrinkage mining method with many examples at home and abroad.
