The method considers borehole data and the stratum distribution laws as follows: firstly, the area of horizontal position of boreholes is divided into several prisms. Secondly, each prism side is connected correspondingly by comparing with ore blocks until the wire frame diagram for the prism is created. Then an irregular triangle network is gradually knitted area by area, layer by layer, and prism by prism. Finally, the 3D stratum model is established based on the concept of solid modeling, which models three-dimension form vividly and makes the attributes of molded ore bodies ceaseless and calculable. Besides, the model is able to automatically deduce problems of complex geological structures by using the knowledge of engineers, such as pinch-out, bifurcation, fault, and wrinkle, etc. The method has the practical value for the reserves estimation according to reserve categories due to two major advantages, namely, 3D display and solid description., correspAuthors=null, authorNote=null,

articleAbstract=矿体赋存条件复杂、地质构造多变。为探究真实地质体情况,通过对现有各类地质体建模方法的分析,尤其是对TIN模型构建、实体(solid)构模的特点进行探讨,提出一种基于工程棱柱体的三维地质建模方法。结合钻孔数据特点和地层分布规律,根据勘探工程的钻孔平面位置将勘探区域划分为若干棱柱体。对每个棱柱体侧面进行矿段对比连接,完成棱柱体线框图搭建,随之逐面、逐层、逐柱构建三角网,直至形成整个地质体的三角网。将实体构模方法结合其中,实现了三维地层实体模型的建立,既能充分反映矿体的三维形态,又能使所显示的三维矿体进行实体描述。使得矿体属性连续并可计算,同时模型能够结合工程师经验自动推理尖灭、分叉、断层和褶皱等复杂地层构造。其具有三维显示又具有实体描述的特点,尤其便于按储量级别进行储量估算等矿量计算,具有实际应用价值。,
