Based on elastic theory and GIS technology, the model of GIS raster digitized model with face element is established to predict mining subsidence. The model can calculate the displacement, stress and strain for any point in any overburden layer. Also the visual result is presented by means of GIS in the case study. The model is proven to be highly effective and particularly aimed at predicting subsidence at any point with any shape of excavation covering a wide range of mining geometry, providing automation, intellection and visualization in subsidence prediction.
