摘　　要：本文通过对二道甸子金矿主矿带已采九个中段金品位的结构变异分析，根据品位的矿化连续极限变程（ａ）、块金效应（Ｃｏ）、结构特征（ｃ）等参数的数值特征及其在不同中段上的变化，揭示出该矿床矿化在空间上具有分段集中富集规律，并指出主矿带深部０～－１００ｍ标高范围内赋存盲矿体。Based on the analysis of structural variation in gold ore grade ofthe 9 mined levels of the main ore belt of Er-Dao-Dian-Zi Gold Deposit andalso according to those parameter characteristics and their variation in differentlevels, such as the limiting variational degree of mineralization continuity of goldgrade, the nugget effect, the structural characteristics ete, this paper brings tolight the regularity of focusing mineralization spatially by stage and pointsout that the blind orebody occurs within 0-100 meters below ground surface.
