Study and Application on the Methods for Predicting Coal and Gas Outburst Based on Neural Tree

Because the complicated non - linear relation between the coal and gas outburst and its affecting factors,for the purpose of predicting the danger of coal and gas outburst in mine coal layer correctly. In this paper a prediction method of coal and gas outburst based on neural tree model, and using multi expression programming and particle swarm optimization algorithms are optimized its own structure and relevant parameters, making a powerful prediction neural tree and classification capabilities, which is constructed by a structured by a structured tree and a set of computation symbols, and which flexible can automatically devise an artificial neural network. Then the algorithm is validated through experimental data. The results showed that the model is a very efficient prediction method for mine coal and gas outburst, compared with the popular predicting methods, and the results indicates the practicability and efficiency of the new prediction model.
