摘要

Rock burst is one of the coal and rock dynamical disasters that must be kept in mind in mining activities.With the increase of mining depth,the risk of rock burst becomes increasingly great.At present,the risk prediction for rock burst mostly is still in the stage of simple statistical study and single factor forecast,making the prediction precision be not a desired one.We propose a Hidden Markov Model (HMM) and a neural network (NN) model for rock burst trained.This model overcomes the deficiencies of existing models by readily incorporating all available information and updating predictions based on observations given by the neural network.
