摘　　要：极薄矿脉在我国黄金矿山和有色金属矿山中分布范围较广,且占有一定的比重。我国脉金矿床极薄矿到薄矿占了58.6%,钨、锡极薄矿脉所占比重更高,因此,高效、经济、安全地回采此类矿石,历来是采矿工作者的重要课题之一。国内极薄矿脉开采主要用到的采矿方法有全面采矿法、留矿采矿法、壁式充填法,国外目前已发展到阶段矿房法、分层充填法等适合极薄矿脉机械化大规模开采的方法。Extremely thin veins are widely distributed in gold mines and nonferrous metal mines in China,and occupy a certain proportion.In China,the proportion of extremely thin ore and thin ore accounts for 58.6%,and the proportion of extremely thin ore veins of tungsten and tin is even higher.Therefore,mining this kind of ore efficiently,economically and safely has always been one of the important topics for mining workers.The main mining methods used in very thin vein mining include comprehensive mining method,shrinkage mining method and wall filling method in China.At present,foreign countries have developed stage room method,layered filling method and other methods suitable for mechanized large-scale mining of very thin vein.
