摘　　要：浙江诸暨金矿属于松软急倾斜薄至中厚矿体。建矿初期,该矿采用留矿法开采,贫化、损失率很高。现改用下向分层胶结充填法进行开采。实践表明该法降低了贫化、损失率并提高了安全性,但生产能力低、劳动强度大及支护材料消耗量大。由此,作者提出并论述了垂直分条胶结充填法,可获得较好的综合经济效益并有较强的适应性。Zhu-Ji gold deposit of Zhejiang Province is classified as soft type of steep dip and thin or medium thick orebody. Since the mine's operation began, the shrinkage method has been employed. As a result of shrinkage mining,great ore loss and dillution took place. Replacing this method with top slicing and cementing filling,the ore loss and dillution were controlled and a safe environment was obtained. However, the problems of lower productivity and higher labor intensity and higher consumption of supporting materials existed, therefore the author of this paper puts forward here the method 'vertical slicing and cementing filling', through which a better economic benefit and adaptability can be obtained.
