| 摘 要： | 结合九里山矿务局实测钻孔资料,采用网格索引算法构建煤层(不规则三角网)TIN,通过计算获得TIN中各角点厚度信息后,映射出煤层顶板TIN模型,并结合实体构模的方法及在OpenGL开放式三维环境下,进行光照渲染等处理,实现了煤层的三维可视化。并利用SketchUp批量处理二维GIS数据,实现巷道三维场景建模;再采用ArcEngine开发包中的SceneControl控件进行二次开发,实现巷道三维可视化。该研究对煤与瓦斯突出预测防治、巷道布局等有指导意义。

| Abstract: | This paper constructed a TIN model of coal seam with grids index algorithm according to real drilling data from Jiulishan Mining Bureau.After obtaining thickness of every corner by the algorithm,TIN model of roof was mapped.Combining solid modeling method and lighting rendering in OpenGL 3-D environment,it realized 3-D visualization of coal seam.It constructed 3-D roadways model by batch processing 2-D GIS data with SketchUP and then realized 3-D visualization of roadway by secondary development with SceneControl in ArcEngine SDK.The research results may be used to direct predicting and preventing coal and methane burst and roadway layout. |
