Abstract：In our country, the probability integration model is most applied as a predicting method in mining subsidence.Predicting parameters of this are variational in different mining degree and the predicting precision for mining subsidence depends on variational laws of dynamic parameters.In order to solve this, a new method for the prediction of dynamic parameters which is exponential smoothing is introduced.By calculating, a field prediction result shows that the average relative errors for every predicting parameter are less than 4 percent.Thus, the method has a certain application value for mining subsidence.
