摘　　要：金厂峪金矿床的围岩为斜长角闪片麻岩和角闪岩类岩石,其遭受动力变质后形成片岩带与矿体密切相关。以探矿者软件为工作平台,建立了该矿床的三维数字矿床模型。通过收集和整理研究区的地质图、地形图、勘探线地质剖面图、钻孔柱状图,建立地质数据库;在此基础上,系统分析区域地质背景,总结区域成矿规律和控矿要素,构建主要控矿地质体的三维实体模型。从模型中清晰可见矿体主要赋存在片岩带中,且严格受构造控制,呈脉状产出,从而证实了三维数字矿床模型的有效性。Wallrock of Jinchangyu gold deposits in Hebei includes plagioamphibole gneiss and amphibolitic rocks.The schist belt formed from these rocks and subjected to dynamic metamorphism is related to ore body closely.3 D digital mineral deposit model of Jinchangyu gold deposit is established by Minexplorer.By collecting and sorting the geological maps,topographic maps,geological sections and profiles,drilling histograms,the ge-ological spatial database is established.The regional geological setting,summed regional metallogenic regularity and ore-controlling factors are analyzed according to this database.Then 3D solid models of the main ore-con-trolling geological body are constructed.The orebody is controlled by structures strictly and assumed veinlike, which can be seen clearly though 3 D geological model.Therefore the effectiveness of 3 D digital mineral deposit model is verified.
