摘　　要：Luangprobang Phabon金矿床位于老挝北部,金矿体赋存于下二叠统厚层状灰岩地层中,受构造控制,属低温热液型金矿床。本文根据研究区以往勘查成果,借助于三维Surpac软件构建了矿床地质数据库,建立了地表模型、矿体模型、块体模型,直观展示了各地质体空间赋存状态及相互关系。首次使用数据统计分析品位厚度变化特征,同时应用普通克里格法估算了资源量,将其与传统地质块段法进行对比分析,认为利用Surpac软件构建的三维模型估算资源量准确、可靠,三维数字化动态数据在矿山实际生产的应用可极大地提高工作效率。Luangprobang Phabon gold deposit is located in northern Laos.The gold ore body occurs in the thick stratified limestone strata of Lower Permian series and is controlled by structure.It is a low-temperature hydrothermal gold deposit.In this paper,according to the previous exploration results in the study area,the geological database of the deposit is constructed with the help of three-dimensional Surpac software,and the surface model,ore body model and block model are established to visually display the spatial occurrence state and mutual relationship of the plastosomes in different places.At the same time,the conventional Kriging method is used to estimate the amount of resources,and the comparison between it and the traditional geological block method shows that the 3D model constructed by Surpac software is accurate and reliable in estimating the amount of resources,and the application of 3D digital dynamic data in the actual production of mines can greatly improve the work efficiency.
