摘　　要：本文利用2232个钻孔及矿山生产坑道资料,焦家—三山岛地区三维地质模型的建模方法和金矿床的三维空间特征,构建了地层、构造、侵入岩、蚀变带及1505个矿体模型,对主要控矿构造与矿体关系进行了三维空间分析,研究了主要矿体的空间分布规律,矿体浅部相对零散,向深部连为一体,规模上有扩大趋势,沿走向上和倾向上无矿间隔较为明显,矿体整体呈现分段富集规律。In this paper,by using datas of 2322 drilling holes and mining production tunnels,a three-dimensional geological model of Jiaojia—Sanshandao area and three-dimensional spatial characteristics of gold deposit,strata,structures,intrusive rocks,alteration zones and 1505 ore body models have been constructed.Three-dimensional spatial analysis of the relationship between main ore controlling structures and ore bodies has been carried out.The spatial distribution law of main ore bodies has been studied.The shallow part of the ore bodies is relatively scattered,and connects to the deep part as a whole.The scale tends to expand,and there is no obvious interval between ore bodies along the strike and dip.The ore body exhibits a segmented enrichment pattern as a whole.
