Geological modeling of a stratified deposit with CAD-Based solid model automation

Abstract The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mining software for determining a solid model, many users try to build geological models in the computer without knowing how these software packages work. As researchers on the subject, we wanted to answer the question "How would we do it". For this purpose, a system was developed for generating solid models using data obtained from boreholes. Obtaining this model in an AutoCAD environment will be important for geologists and engineers. Developed programs were first tested with virtual borehole data belonging to a virtual deposit. Then the real borehole data of a cement raw material site were successfully applied. This article allows readers not only to see a clear example of the programming approach to layered deposits but also to produce more complicated software in this context. Our study serves as a window to understanding the geological modeling process.

摘要 采矿活动的规划阶段需要开展大量全面且细致的分析工作。确定准确的矿体模型是规划的首要环节，亦是最为关键的步骤之一。三维实体建模是可精准勘查矿床空间位置与赋存形态的重要技术手段之一。尽管当前已有多款可用于构建实体模型的采矿专业软件，但不少使用者在未掌握软件运行逻辑的前提下，便尝试在计算机中搭建地质模型。作为该领域的研究者，我们希望解答“我们应当如何开展此项工作”这一核心问题。为此，我们开发了一套基于钻孔数据生成三维实体模型的专用系统。在AutoCAD环境中生成该模型，将为地质学家与工程师的工作提供重要支撑。所开发的程序首先采用虚拟矿床的虚拟钻孔数据开展测试验证，后续又将其成功应用于某水泥原料矿区的实际钻孔数据场景。本文不仅可为读者呈现层状矿床编程建模的清晰范例，还可助力其在此领域开发更为复杂的专业软件。本研究可为理解地质建模流程提供参考窗口。
