基于MultiPatch的煤矿巷道三维模型的构建研究

Researching the Construction of 3D Model of Mine Roadway Based on Multipatch

针对目前煤矿巷道三维建模中存在的灵活性和可移植性差等问题,提出了一种基于ArcGIS MultiPatch的煤矿巷道三维模型构建方法。该方法是在ArcGIS Engine平台下,利用C#语言进行二次开发,根据巷道各个断面的顶点坐标生成MultiPatch面,实现了煤矿巷道的三维建模。以单巷道体模型为基础,构建了部分煤矿巷道网络图。该研究丰富了巷道建模理论,对矿山安全生产具有重要意义。

Aiming at the problems of poor flexibility and portability in three-dimensional modeling of roadway of coal mine, this paper proposed a three-dimensional modeling method of roadway of coal mine based on ArcGIS MultiPatch. This method uses C# language to carry on the secondary development on ArcGIS Engine platform. According to the vertex coordinates of the sections of roadway, MultiPatch surfaces are generated, so as to realize the three dimensional modeling of the coal roadway. In terms of single roadway model, the part of underground mine roadway network would be constructed. Thereby the study could enrich the theory of modeling of roadway,and is significant for safety production in coal mine.
