Chemical Characteristics and Discriminant Model for Water Bursting Source in Suntuan Coal Mine

In order to realize accurate and quick discrimination of mine water bursting source type, we analyze the water chemical characteristics of main aquifers in Suntuan Coalmine and use SPSS to study the water samples of main aquifers by the stepwise analysis based on the test results of Na⁺+K⁺, Ca²⁺, Mg²⁺, Cl^-, SO^2-₄, HCO^-₃. On the basis, Ca²⁺, Cl^-, SO^2-₄, HCO^-₃ are chosen to establish discriminant model suited to Suntuan Coalmine water bursting source. After verification, the result shows the model has better effect on discrimination.
