APPLICATION OF GRAY THEORY IN STUDY OF PREDICTION OF MINE WATER INFLOW

This paper imitates the mine water inflow of Sangshuping Coal Mine in Shaanxi Province by using gray system GM(1,1) model and sets up the rectified model to predict water yield from 1998 to 2001.The operation results show that the prediction is very precise and can be used in imitation,control and prediction of geological data which has gray characters.
