Abstract: Based on the SURPAC software, a 3D modeling method on complicated geologic body combined with Delaunay triangularization method and linking adjacent contour method were introduced. Taking the Dalingxishan magnesium mine as an example, the digital terrain model and the 3D model of the goaf group were built. Based on the TCL language and the automatic modeling program of rock movement scope according to the goaf bottom contour data, the critical angle of rock deformation and the target projection height were developed. Then the program was used in the Dalingxishan magnesium mine to obtain the 3D model of the rock movement scope. According to the Boolean calculation result of the rock movement scope model and the digital terrain model, the surface movement boundary was determined immediately.

Key words: metal mine, goaf group, SURPAC, 3D model, surface movement
