摘　　要：从理论和实验两方面,对不同放矿截止品位及其相互之间的关系进行了研究,并得出结论:不同放矿截止品位及其相应的放矿方式在最初提出时所建立的理论基础不同,但是相互间仍然存在着内在的本质关系,极限截止品位放矿方式、无贫化截止品位放矿方式都是组合截止品位放矿方式的一种特殊形式,但是各自具有不同的特点、不同的适用条件,会得到不同的经济效果。在实践中,宜实施适当的组合截止品位放矿。From the two aspects of theory and experiments, the different cut-off grades for ore drawing and the relations among them were studied and some important conclusions were drawn, that are, although the different Cut-off Grades for Ore Drawing were put forward originally based on different theory, but there are still inherent substantial relations among them; both extreme cut-off grade ore drawing and undiluted ore drawing are special ways of combined cut-off grade ore drawing, but have different characteristics, application conditions and can cause different economical effects; in practice suitable combined cut-off grades shall be adopted for ore drawing.
