摘　　要：陕西山阳西龙头沟金矿属急倾斜、薄矿脉难采矿体,若采用传统的采矿方法,势必产生较大的贫化、损失,造成资源的浪费。根据该矿体赋存状态,推荐采用窄分段分采空场法,可最大限度减少贫化、损失,提高资源的利用率。The Xilongtougou gold deposit in Shanyang county, Shaanxi is a steeply - inclined narrow orebody. Using traditional mining methods will bring lots of dilution, loss and waste of resources. According to the occurrence of this orebody, a narrow - sublevel open stoping mining method was brought out. Using this method, the resources can be utilized effectively.
