Prediction of the bolt supporting parameters of mining tunnels with the artificial neural networks based on mixed learning algorithm

Abstract：To determine the mining tunnel bolt?supporting parameters is important but difficult in coal tunnel supporting design all the time.The authors have tried to use the mixed learning algorithm of error back propagation and simulated annealing algorithm to predict the bolt?supporting parameters.The result indicates that this method is speedy, easy, practical and intelligent.The selection of the bolt?supporting parameters will be more scintifical, rational and effective in this way.
