Seawater poses a great threat to the Xinli Mine, an undersea gold mine in China. A hydrochemical method was used to assess the risk of sea water inrush into the mine. A detailed hydrochemical survey and sampling were carried out and the concentrations of conservative ions in the mine water were analyzed. Principal component analysis indicated that the potential water inrush channels were located in the hanging wall of the ore-controlling fault. A composite principal component was calculated from the Na+, Cl-, Mg2+, SO4 (2-), and K+ concentrations, which reflected the effects of potash feldspathization and cation exchange, to assess the risk of seawater inrush.
