摘要

Categorical principal components analysis (CATPCA) and hierarchical cluster methods were employed to analyze the groundwater of each aquifers in Dingji mine,and the variables of the analysis are Ca2+,Mg2+,K++ Na+,HCO3 -,Cl- and SO4 2-.By using the method of CATPCA,the relationship between each water sample,the relationship between the six water quality indicators,and the relationship between the water samples and indicators were analyzed,which reflect the change law of water samples and variables,and the groundwater chemical characteristics of each aquifer in Dingji mine were revealed.The six water quality indicators were analyzed with hierarchical cluster,and the results conform with those of CATPCA analysis.The results of the analysis can offer advices for water damage prevention and control in coal mine production.
