Based on the mapping theoretical method, the deformation surface set model is established, which represents time series of slope 3D solid deformation. The phase in the series is deformation surface. Therefore, model set is dynamic deformation surface set of slope 3D solid deformation. Surface of deformation function reflects the distribution of slope rock mass deformation value in the special region, thus it can reveal the slope deformation law in different sections better. By engineering applied, the establishment of slope 3D deformed prediction model makes the behavior of slope rock mass deformation more direct, while makes it convenient for slope judgment of division and safety evaluation, so as to the decision basis for mine safety production and engineering control.

Considering the material property of the rock to the dangerous rock mass,the paper Looks the model parameter of AR( 1) model as the status vector, and uses Kalman filter method to analysis the deformation of the dangerous rock mass. The result shows that the method can improve the accuracy of fitting and forecasting of the model.
