Abstract:Fenghuangshan iron deposit in Cangshan county is hidden low grade iron deposit, and hydrogeological condition belongs to medium type. Hydrogeological logging and pumping tests of inspection holes of main shafts, auxiliary shafts, intake shaft, Dongfeng well and Xifeng well bore wells have been carried out. Setting inspection holes of main shaft as an example, four ore[CD*2]bearing layers have been dvided, the aquifer hydrogeological parameters have been obtained, and shortage of water inflow diameter has been predicted. Hydrogeological characteristics, such as aquosity has been identified basically, grouting segment has been determined. It will provide design basis for making water prevention programs mine shaft .
