基于GIS的矿山开采沉陷信息可视化应用

GIS-based visual application of mining subsidence information

矿山地下煤层开采引发地表沉陷变形,可造成土地破坏、房屋倒塌等一系列灾难性后果。基于概率积分法开采沉陷预计结果,利用ArcGIS的ArcScene模块实现地表变形预计数据的三维可视化表达,并以预计的下沉量为例进行可视化结果的等值线绘制、任意剖面图制作、任意点位形变信息提取应用分析。

Underground mining in coal mine must cause land surface transformation so that a series of geo-hazards will be occurred such as land destroy,waterlogging,landslide and house collapse.Based on ArcScene module of ArcGIS,this paper shows the three dimension visual performances of mining subsidence data predicted by probability integral method,and analyze some applications of mapping contour,DEM,subsidence,inclination,curvature,horizontal displacement,horizontal deformation and so on according to the visual res...
