Research Into The Way of Forecasting Coal and Gas Outburst Applying Artificial Neural Network Numerical Analysis Combined with The Fault Tree Methods

摘要

Based on the gas and geology theories,by creating a general fault tree model of coal and gas outburst,and by applying its quantitive computing method,the dominant factors are discovered ,which always lead to the happening of outburst and can be used to partition the coalfield into different gas-geology section;Following that, a non-linear numerical model for forecasting coal and gas outburst is built combined with artificial neural network numerical analysis methods,and some perfect computing conclusions have been acquired by the processes.On the other hand,some valuable attempts to research into gas-geology and to forecast coal and gas outburst by quantitive numerical methods are introduced in the paper.
