Abstract：The 3839 coal face in the West Wing 8 crosscut of the 13 level in the Zhaogezhuang mine,is a deep mining of steeply dipping coal seam after nearly 100 years’mining. In order to predict the mine water discharge of the 3839 coal face,firstly,we carried out the detailed analysis of the mining area of upper 9~13 levels in nearly 30 years,in terms of precipitation,Ordovician limestone water level,mining depth,and the correlation between the mining area of upper level and the mine water discharge. Secondly,we selected factors of discharge,precipitation,the change magnitude of Ordovician limestone water level and mining depth. Final-ly,through the establishment of multiple linear regression analysis and forecasting model (equation ),after validating the function by using the discharge data of 2012,we can conclude that the regression factor is highly correlated. After predicting mine discharge in the 3839 coal when mining in 2013,the results are close to the predicted by use of the analogy method and the analytical method. It is suggested that this method is feasible in the prediction of mine water discharge,but not having universal applicability.
