摘　　要：广西大厂矿田长坡—铜坑矿区矿床形成与分布的主要控制因素有地层岩性、岩浆岩体和断层、褶皱构造。结合大厂矿田多年来积累的地质资料信息,提取了钻孔、坑道采样化验数据与地质体的几何取点等矿床隐伏矿体预测专题数据,建立了各种地质体几何模型;以此为基础进行控矿地质条件的定量分析,以立体单元形式对地质空间进行分割抽样,提取了立体单元控矿作用定量化指标;通过一种有效的矿床三维数学模型建立方法,对矿床地下三维空间中隐伏矿体进行了定位、定量预测和结果验证,并开发了预测结果的三维可视化动态查询系统。Main ore - controlling factors in the Tongkeng deposit of Dachang mine include rock formations of strata, magmatic rocks, faults and folds. Based on geological data accumulated since the deposit was discovered, special data for concealed ore prognosis, such as drills, sap and point sampling of geological bodies, is abstracted. Thus, geometrical models of geological bodies are established and ore -controlling factors are modeled quantitatively by three - dimensional grid. Three - dimensional model of the deposit is established and tested. The prognosis results for three - dimensional localization and quantity are checked. Furthermore, a three - dimensional visualization dynamic - query system for the prognosis results is developed.
