Application Study on Cross-orientation Method of Groundwater Grey Numerical Model in Prediction of Mine Inflow

In this paper,further research was carried out on the solution method for the grey numerical model of groundwater and a cross-orientation method was established in order to make the application of the grey theory more sophisticated in the numerical calculation of groundwater.Grey numerical simulation of the groundwater level was conducted with this cross-orientation method in Baijian Iron Mine and the water inflow of the mine was obtained through prediction.This simulative research can provide a new method for the study of groundwater calculation and promote the development of grey theory.
