摘 要: 以新疆某煤矿含煤地层为建模对象,以矿区内收集和整理的钻孔资料为数据基础,以基于面模型的多层不规则三角形网(triangulated irregular network,TIN)建模理论和方法为指导,运用ArcGIS10对钻孔表格数据进行转换并建立钻孔数据库。依据岩性对岩层进行分层处理,利用TIN构网技术构建各岩层界面,通过面拉伸和合并的方法构建地质体三维模型。在建模过程中为避免复杂性、重复性操作,实现三维建模的流程化、自动化,采用ModelBuilder构建流程化的层状地质体模型,并将该模型转换为ArcPy模型文件,基于ArcPy模型文件,使用ArcEngine和C#语言开发地质体三维建模与可视化应用系统,从而实现层状地质体建模和三维显示功能。
关 键 词: 地质学;钻孔数据;模型构建器;ArcPy模型;地质体三维模型;ArcEngine

Abstract: In this paper, we took a coal mine in Xinjiang as modeling object and took drilling data in the mining area as the data base. Then we transformed drilling table data and established the borehole database by using the ArcGIS10. Based on the lithology of strata hierarchical processing theory and method of multi-layer triangulated irregular network (TIN) modeling in surface mode, we established 3D geological body model by using stretching and folding method. In order to avoid the complexity and repetitive operation in the modeling process and realize the workflow routing and automation, we used ModelBuilder to build a layered geological body model, and converted the model to ArcPy model file. The 3D geological body modeling and visualization application system based on ArcEngine and C# language were developed by using ArcPy model file. Finally, the layered geological body modeling and 3D display functions were realized.
Key words: geology; drilling data; model builder; ArcPy model; 3D geological body model; ArcEngine
