Application of Water Finger-print Method in Discriminating Sources of Mine Water Bursting

According to the water quality data of a mine in Fuquan City, Na⁺，Ca²⁺，Mg²⁺，NH⁺₄，Cl^-，CO^2-₃，K⁺，SO^2-₄，NO^-₂，Fe²⁺，HCO^-₃，pH, total hardness, salinity, redox potential 15 indexes are chosen as the coordinate dimension to establish the discriminant of water source finger-print map for mine water bursting, and we discriminate three water bursting source samples. Finally, the distance discriminant method verified the accuracy of the judgment result. The results showed that: mine water finger-print map can well and quickly determine water bursting source, and the determination of mine water bursting source provides a new way.
