基于三维可视化技术的隐伏矿体预测

A 3D method for predicting blind orebodies,based on a 3D visualization model and its application

在现代成矿预测理论研究基础上,利用已有的商业三维地质建模软件,建立了一套基于三维可视化技术的隐伏矿体三维立体定量预测方法和流程,结合云南个旧锡矿实例探讨大比例尺隐伏矿体三维定量预测的数据预处理、三维地质建模过程和三维定量预测方法。使用三维可视化技术结合找矿信息量法确定了研究区找矿有利靶区,计算了含矿远景单元的找矿概率,估算了工程验证区金属资源矿体量。应用实例表明了应用三维可视化技术进行隐伏矿体三维定量、定位和定概率的有效性。

Based on the study of existing orebody predicting theories and using commercial 3D geological modeling software,we established an integrated 3D quantitative method and procedure for locating blind orebodies,based on a 3D visualization model.In this paper,we discuss the procedures of this 3D visualization method,such as data preprocessing,3D geological modeling process and 3D quantitative prediction.Using the 3D visualization method,we established favorable prospective targets,calculated the ore-containing p...
