基于剖面的山东省龙泉站金矿矿体三维模型的建立与应用

3D modeling and application of Longquanzhan gold deposits in Shandong based on section planes

针对山东省龙泉站金矿现状研究中存在的问题,提出了建立龙泉站金矿区地质体(金矿体、金矿化体、断层)三维模型的解决方法,利用VC++和OpenGL语言开发了针对金矿的三维地质建模与可视化系统,在该系统中以金矿区已有的地质体剖面为基础数据建立了矿区金矿体、金矿化体、断层的三维实体模型;模型展示了金矿地质体的空间形态及相互关系,显示了矿化蚀变带特征;并根据模型显示形态结合成矿地质背景对矿区深部找矿前景进行了初步预测。因此,金矿区地质体三维模型的建立与应用对于完善数字矿山工程、提高生产工作效率、加快矿业信息化建设具有十分重要的意义。

Based on the analysis on the problems existing in the research of Longquanzhan gold deposits in Shan-dong province, the paper puts forward the methods to build the 3-dimension （3D） solid model for the geological bodies in the area, including gold orebodies, gold mineralized bodies and faults. Taking Visual C^＋＋ and OpenGL as developing tools, the paper builds up the 3D geological modeling and visualization system, including the 3D solid models of the gold orebodies, gold mineralized bodies and faults in the research area; the models present the spatial form and mutual relationship of the geological bodies, reveal the characteristics of the mineralization alteration zone. According to the orebodies form and the geological background in the research area, the paper forecasts the deep orebodies preliminarily. Above all, the establishment and application of 3D models plays an important role in perfecting digital mine project, in improving production efficiency and in accelerating information construction of the mine.
