A new idea was put forward for chaotic characteristics and time-variable law of surface subsidence of goaf by means of EMD and prediction methods of chaotic. Problems of space reconstruction of IMFS, establishment chaotic prediction model and application of model were discussed. EMD-SVM methods were used for modeling and predicting the goaf subsidence. The result of the simulation experiment shows...
