Abstract: According to the non-continuous model-probability integral method, and combined mining subsidence prediction system（MSPS) on independence development, mining subsidence prediction of an iron mine in Luan City was analyzed.In order to check the influence of mining subsidence on the mining areas, the way through the interface to call the surfer for drawing the contour lines and expressing 3D visualization.It can provide guidance for safe production.

Key words: Metal mine, Mining subsidence, Surfer, Probability integral method, 3D visualization
