摘　　要：通过对不同放矿截止品位及其相互间的关系进行研究 ,有了一些新的认识 :组合截止品位放矿方式 (形式、方案 )包括了一切截止品位放矿方式 ;根据放矿形式是不可避免的 ,组合截止品位放矿可能有许多方案 ,无贫化放矿仅仅是其中的一种特殊形式 ,组合截止品位放矿各种方案中有一种或者几种方案为最优 ,可使矿山生产总赢利为最大等等。After studying on the different cut-off grades for ore drawing and relations among them, some new knowledge is got: that is, combined cut-off grade ore drawing includes all kinds of cut-off grade ore drawing. Since the ore drawing is inevitable, there're many kinds of plans for combined cut-off ore drawing, in which undiluted ore drawing is only one special way. There're always one or several kinds of optimal plan, which can make the most profit in mining production.
