激发极化法测得的四组参数p、h、J和D，是判断煤矿采空区积水情况的重要依据。但在传统的资料处理过程中，作图量大，且异常特征不明显时又难以作出准确的判断。而数学地质中的聚类、判别分析方法，可以很好地解决这一难题。本文以实例介绍了这种方法的应用效果。 The four sets of parameters p, h, J and D measured by the excitation polarization method are important basis for judging the water conditions in the coal mined area. However, in the traditional data processing, it is difficult to make accurate judgments when the amount of drawing is large and the abnormal features are not obvious. The mathematical geology in the cluster, discriminant analysis can be a good solution to this problem. This article introduces the application of this method with examples.
