Distribution Prediction of Advanced Abutment Pressure of Based on BP Neural Network Model

Based on the analysis of the distribution laws of abutment pressure at the working face, we predict the law of abutment pressure using artificial network technology. We selected seven influence factors of abutment pressure including mining depth, mining height, coal seam inclination angle, workface inclined length, coal body strength, strata stability, and structure of overlying strata. The law of abutment pressure forecast model was established based on artificial neural network. Result shows that actual measurement results and predictive values of the model have goodness of fit, and the error is in the acceptable range.
