MARGIN: 0cm 0cm 0pt" class=MsoNormal>man">///In this paper, based on the correlatability analysis of sharp pressure drop and water radon and water mercury changes caused by geothermal exploitation in Wang-3 and Wang-4 wells after July mas-microsoft-com:office:smarttags" />2004 in Jingjinxincheng, the authors find that geothermal exploitation is the root cause of affecting earthquake observation in Wang-3 and Wang-4 wells despite different horizons and depths of geothermal aquifer and earthquake observation. Then, the authors analyzed the factors that influence the water chemistry behavior in Wang-3 and Wang-4 wells due to geothermal mining from the aspects of geological structure, development of Karst fissure, underground hydrodynamic condition, heat-dynamical condition, physical-chemistry equilibrium of underground water, and so on. Furthermoman">re, the authors put forward some suggestions about site selection and construction of water chemistry observation well in geothermal anomaly area.mas-microsoft-com:office:office" />
