摘 要: 运用大型三维矿业软件SURPAC创建某矿深部矿段的地质数据库,可视化解译地质钻孔编录包含的断层、地层和矿体信息,构建断层、地层和矿体的三维模型;在建立该矿段品位块体模型的基础上,采用普通克立格法对矿体有用元素品位进行估值,并对矿段有用元素的平均品位和地质储量进行统计计算。以所建立的地质数据库和断层、地层、矿体和井巷工程三维实体模型为基础,实现包含矿体、断层、地层、巷道、钻孔、坐标、比例尺、标题栏等多种图元信息的地质剖面自动成图。实际应用结果表明:基于钻孔编录信息可视化解译所建立的矿床三维模型可靠,地质剖面出图能满足工程应用要求,具有重要的应用价值。

Abstract:Geological databases of the deep deposit in a mine were established, the geological drill-hole information including faults, stratums and ore-bodies was interpreted visually, and 3D models of faults, stratums and ore-bodies were established by using 3D mining software SURPAC. Ordinary Kriging was used to evaluate the grade of useful elements of the ore-bodies; the average grade of useful elements and geological reserves were computed statistically. Geological section-drawing was automatically created based on the established geological databases and the 3D models of ore-bodies, faults, stratums and sinking and driving engineering, including manifold graphics element information such as ore-bodies, faults, stratums, laneways, coordinates, scale title bar and so on. Practical application results show that the deposit 3D models based on visible interpretation of drillhole information are reliable and the geological section drawing can meet the need of engineering applications.

 

Key words: drillhole information; ore-bodies; 3D modeling; reserves estimation
