【Abstract】 The routine methods for predicting gas outburst are briefly introduced and their drawbacks pointed out. By turning the unequal interval array into equal interval array to predict gas outburst in mine, and referring to grey system prediction method, the dynamic GM (1, 1) model is set up, in which the initial data of gas outburst in different depth are used. The model is exemplified with a realistic case. By choosing the rational error test model, the prediction result is rather preferable showing good guidance in predicting gas outburst when extending the mining depth and realizing mine safety.更多还原
