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。
In view of the deficiency of the three-dimensional topography in the mining subsidence can not be considered in the existing mining subsidence 3D visualization method, this paper calculates the three-dimensional coordinate deformation prediction and coordinate fusion calculation of the mining surface by mining subsidence prediction program in computer language. Based on the data transmission method and ArcGIS To realize the three-dimensional visualization of mining subsidence that takes into account the three-dimensional topographical features of the mining area. The three-dimensional surface generated by the method overcomes the deficiencies of the existing mining and subsidence 3D visualization methods that can not show the movement and deformation status of the mining area after the surface subsidence, and can make full use of ArcGIS’s powerful spatial analysis and spatial data query functions to realize the GIS Good application in the field of mining subsidence.
