Abstract：Based on the principle of Mahalanobis Distance Discriminant Analysis (DDA), the distance discriminant a-nalysis model to determine the water-bursting source of mine was established. According to the chemical analysis of the aquifer water in underground shafts, six indexes of water-bursting source determination of mine were taken into account to build a forecast DDA model. Linear discriminant functions were obtained through training of thirty-five sets of in situ data. Each of the thirty-five sets of samples was tested by using resubstitution method according to the DDA model, and the correct rate was equal to 97. 14% after the DDA model was trained. The other four sets of samples were predicted by using this model to test the discriminant ability of DDA model. Moreover,the proposed method was used to deter-mine water source determination of Wutongzhuang Mine water-bursting. The results show that DDA model classification is good, prediction accuracy is high, misjudge rate of resubstitution is 0. 028 6.
