Abstract: Water prevention and control is an important link in underground mine construction, Baixiangshan iron deposit is a complex water-rich metallic one. In order to realize a comprehensive prevention and control of the water inrush when constructing a laneway passing the fault, based on the investigation on the hydrogeological conditions and water inrush law of this deposit, the basis of water inrush control and the specific method are put forward. On this basis, a scheme of curtain grouting for water blockage and control is worked out, which can be certain reference to the mining of deposits with similar special hydrological conditions.

Key words: Water-rich deposit, Water-guiding fault, Water exploration, Curtain grouting
