Distinguishing the Sources of Water Inrush in Zhuji Coal Mine by Hydrochemical Characteristics

In this paper,the water sample data of different types of aquifer in Zhuji Mine Field were analyzed and processed,the water quality of the water injection point was compared with that of the aquifer in the mine field by using the Piper diagram and the grey correlation theory,it was concluded that the water source of the water injection point came from the nascent aquifer.The results show that Piper diagram can well analyze the hydrochemical characteristics of aquifers,and the gray relational theory can eliminate the relevant disturbing factors,as well as accurately identify the source of water,the combination of the two can quickly and accurately identify the water source of the mine field,thus providing a theoretical basis for the prevention and treatment of mine flood.
