| 摘 要： | 利用有限的煤矿勘探数据,建立煤层底板的高精度等值线图对于煤矿巷道设计、煤层开采具有重要意义.采用两条技术要求来实现高精度等值线的绘制,一是采用Delaunay构网建立原始离散采样点的不规则三角网(Triangulated Irregular Network,TIN);二是对初始TIN模型进行网格加密,形成均匀分布的三角...

| Abstract: | For mine tunnel design and coal seams mining,it is important to build high precise contour of coal floor based on limited exploration data.For building high precise contour,two technical requirements are proposed,one is to build Triangulated Irregular Network(TIN) based on Delaunay,the other is using Delaunay Refinement based on the initial TIN to form uniform mesh.For the insert point,its attribute value is acquired by Kriging interpolation.Then,high precise TIN is achieved.For tracing contour,a new method... |
