【Abstract】 According to gray theory, the gray GM(1,1) model for predicting the outflow of min is established in the paper, at the same time the established GM(1,1) model is modified with the residual sequence. The prediction example Shows that the precision of the modified model can meet the necessity of practical engineering, so can be applied to predict the outflow of mine methane.更多还原
