Abstract In order to improve the coal and gas outburst along the shaft uncovering, coal seam thick, gas pressure prediction accurang, coal seam bury depth, drilling power phenomenon, drilling gas flow, 5 indexes were taken as variables to predict coal and gas outburst, based on the obscure neural network theory, the variable was dealt obscurely, obscure neural network prediction of coal and gas outburst was constructed, the sample was trained and tested, the constructed obscure neural network prediction was accurate, the predicting outcomes met the needs of engineering practice requirements.
