Predicting model for back analysis of non linear dynamical features in strata motion

In this paper, from the non linear dynamical view, the authors put forward the predicting method of strata motion with in situ measured data. The researches show that there would be considerable errors for long term forecast because of non linear dynamical features of strata motion, therefore to set up short time model by taking new information is a good way to realize the reliable prediction for strata motion. It is helpful to the prediction of coal and rock burst.
