Directing at the non-linear dynamic characteristic of water inrush from coal floor and the weakness analysis of current forecast methods for water inrush from coal floor, a new forecast method is raised based on wavelet neural network. Firstly basic principles of wavelet neural network are described in this paper, then a forecast model for water inrush from coal floor based on wavelet neural network is raised and analyzed, finally an example is illustrated to verify the feasibility and superiority of this method. Conclusion shows that the forecast result based on wavelet neural network is more precise, which is more beneficial to the prevention and control of water inrush from coal floor in coal layer.
