DTM在开采沉陷可视化预计中的应用

Application of DTM in visualization prediction of mining subsidence

数字地面模型(DTM)具有强大的三维可视化分析和空间模拟功能,它可以代替等高线对地形表面的描述,能满足对等高线数据相同的各种需求。为了充分地利用地质、矿山等许多领域的三维原始数据,以开采沉陷预计为研究对象,首先提出了将DTM用于地表移动变形可视化预计的意义,然后对其DTM构造的思路和方法进行了研究,最后,结合实例,介绍了将DTM用于开采沉陷可视化预计可以得到的最终成果。

Digital terrain model(DTM) has powerful function of three dimensional visualization analysis and spatial simulation, which can replace contour describing terrain, and can meet the various needs of the same contour data .In order to make full use of three dimensional raw data in many fields, such as geology,mine etc. This article takes mining subsidence prediction as the study subject. Firstly, the necessity of applying DTM in the visualization predicting the ground movement is presented. Then, the ideas and methods of constructing its DTM has been studied, In the end, the final results of visualization predicting the mining subsidence obtained from the DTM are introduced.
