In this paper, the implementing method of updating the coal mining area’s DEM by mining subsidence forecast data is introduced. The data file of mining area’s elevation points can be generated by extracting from the digital topographic map of coal mining area, and after the interpolation and encryption of extracting mining area’s elevation points, the data file of the mining area’s collapse can be obtained by subtracting the values of the subsidence forecast from the elevation values of the mining area’s elevation pionts. According to the data file of the mining area’s collapse, DEM of the mining area’s collapse can be generated, and the corresponding contour map can be also generated. This has important significance for the environmental management and disaster prevention engineering design of coal mining area.
