英文摘要Water inrush is a potential disaster in the Sanshandao Gold Mine, which is located on the coast of the BoHai Sea. A conceptual model based on the water chemistry and hydrogeological setting was established to identify potential water sources. Then, a mixing pattern was developed based on the delta O-18 and Cl- values. Finally, a linear mixing model was used to estimate the mixing ratios of water sources at each site. Four sources were identified: freshwater: (F), quaternary water (Q), seawater (S), and brine (B), and four mixing patterns were developed: B-F-Q, F-Q-S, B-Q-S, and B-S. The mixing ratios showed that brine was the main water type when mining began. However, seawater (mean = 48.3%) and quaternary water (mean = 36.04%) came to dominate the groundwater composition over a short period of time. The field investigations and hydrochemical analysis indicated that the main flow paths of these waters were along NW-oriented fractures and the F3 fault. Freshwater mainly recharged the shallow fractures (above -285 m) and represented a small proportion of the groundwater (mean = 11.2%). The main freshwater flow paths were bare rock fractures in the mountains.
