Risk Prediction of Long Inclined-Shaft Construction in Mine by TBM Based on Chaotic Time Series
Nonlinear chaotic time series is used to predict risk of long inclined-shaft construction in mine by TBM based on analyzing its character.Phase space of risk time series of construction by TBM is reconstructed; time delay and embedding dimension is also obtained.Maximum Lyapunov index of risk series in long inclined-shaft construction by TBM is obtained by using small data quantity method.It proves that the risk time series in long inclined-shaft construction by TBM has characteristics of chaos.AOLLM-BP prediction model is put forward which can predict the tendency of risk time series changing with time.Simulation experiments show that the prediction model has strong ability and better predictive effect on risk of long inclined-shaft construction in mine by TBM.
