%X Multilayer digital elevation model is simple and effective in building a three-dimensional stratigraphic model. Based on the borehole data of a coal field, different geological layers are identified. The method for gathering and processing the data of the cross-layer and absent-layer is proposed. The elevation contours of the different layers are obtained with the processed elevation data. The Kriging interpolation method is used to get the data of the strata for the three-dimensional stratigraphic model of the mining area. The profile diagrams are drawn from the built three-dimensional stratigraphic model and compared with that of the same sections by manual drawing. The results show that the former model is more reliable than the latter. Finally, the numerical simulation with finite element method is carried out by drawing data from the built three-dimensional stratigraphic model. The simulating results also show that they agree fairly well with the results obtained by geological survey and those gathered in coal mining process and can be used in coal mining design and tectonic prediction.
