It is very complex between the each kind of essential factor of the coal and gas prominent and the phenomenon of the prominent,and there is very obvious misalignment character.The BP artificial neural networks model,we can approach this kind of nonlinear function relations well.Based on the analysis of the coal and the gas prominent character index,we can establish the reasonable single cryptoclastic texture BP forecast medal,and realize the training and the forecast to the model which using the MATLAB neural network toolbox.The application result indicated that this prominent forecast technique has the very high counting yield and the forecast precision.
