Water control measures based on groundwater dynamic monitoring in the southern area of Sijiaying iron mine

The southern area of Sijiaying Iron mine belongs to the domestic rare watery deposit. To understand the hydrographical geological condition of the Southern area is the key to determine the safe mining project and water control. The article use the method of combining groundwater dynamic monitoring with exploration data to analyze the hydrological geological conditions in mining area, through the analysis of dynamic characteristics of water level of quaternary and the bedrock aquifer, analyzing Separating Water ability of lower quaternary aquifuge, the groundwater runoff, channel, aquifer recharge relationship and boundary conditions. then, puting forward that the lower quaternary "skylight" and Xin River fracture is an important channel of mine water conduction. And in the light of Dajiazhuang mining, putting forward some control suggestions. In addition, the analysis methods is more targeted to some mine that is not conducted hydrogeological test.
