| 摘 要： | 针对已有开采沉陷三维可视化方法中不能考虑矿区三维地形特征的不足,本文通过计算机语言编制开采沉陷预计程序对矿区地表点进行三维坐标变形预计计算与坐标融合计算,并基于数据传输的方式与ArcGIS进行结合,实现了顾及矿区三维地形特征的开采沉陷三维可视化。利用该方法生成的三维表面,克服了已有开采沉陷三维可视化方法中不能表现矿区地表塌陷后移动和变形状况的不足,而且能充分利用ArcGIS强大的空间分析与空间数据查询功能,实现了GIS在开采沉陷领域中的良好应用。

| Abstract: | In view of the shortcoming existed in the 3D visualization method of mining subsidence without considering the 3D terrain features in mining areas,the paper conducted the modification calculation of surface 3D coordinate in mining areas through adding the function of 3D coordinate modification and 3D coordinate fusion calculation in forecasting program of mining subsidence,and combined with ArcGIS through the data transmission.the 3D visualization of mining subsidence considering 3D terrain features in mining areas was realized by means of ArcGIS.3D surface map produced with the new approach could vividly represent the situation of displacement and distortion of mine surface after subsidence compared with the existed 3D visualization approach,it could also use the spatial analysis and spatial data query functions of ArcGIS,realizing the good application of GIS in mining subsidence area.It could provide a reference for the project design of disaster prevention engineering of mining subsidence. |
