Abstract: As the typical structural fissured water pour-in deposits, the groundwater pour-in mechanism of Xiadian gold deposit, Zhaoyuan City in Shangdong Province, is evidently influenced by Zhaoping mineralizing structure. It is particular for the study of groundwater pour-in mechanism controlled by the structure. The structural information and evolution of the fissured-water pour-in on the basis of theory about Zhaoping structure mineralized dynamic system are analyzed. Meanwhile in virtue of the hydrogeological conditions and groundwater pourin characteristics, the mode of structural control about groundwater pour-in mechanism in Xiadian gold deposit is discussed, and made the conclusion that the structural fissured water dominated by Zhaoping structure dynamic system is the primary source of pit water.

Key words: Xiadian gold deposits, Zhaoping fracture, groundwater pour-in mechanism, control mode, structural fissured water
