摘　　要：首先详细阐述了建立矿山开采沉陷DEM的方法,提出了利用GIS的空间分析功能进行开采沉陷时空变化分析的技术方案。以鲁西煤矿为例,利用基于CORS的网络RTK进行矿山开采沉陷外业数据采集,通过后两期生成的DEM与首期生成的DEM进行叠加,生成后两期累计沉陷值DEM,利用Arc GIS的空间分析工具对累计沉陷值DEM进行空间分析,生成了沉陷等值线和沉陷面积统计报表。利用上述方法可以经济、有效地反映矿区地表沉陷的时空变化及对周围环境的影响程度和范围,为矿区生产设计和环境评价提供决策依据。This article first elaborated the establishing method of DEM in mining subsidence, proposed the technical solutions that u- sing GIS spatial analysis functions to analysis the temporal and spatial variations in mining subsidence. Luxi Coal Mine as an example, using network - RTK based on CORS to collect field data of mining subsidence, generated the DEM of accumulated subsidence values by the superposition of the latter two phases with the first phase of the generated DEM, spatial analyzing for accumulated subsidence values DEM by using ArcGIS spatial analysis tools, generated subsidence contour and subsidence area statistics. Using the above methods can be economically and effectively reflect the temporal and spatial variations of mining subsidence, the impact on the surrounding environment, and making decision basis for the mine production design and environmental assessment.
