摘　　要：本文采用井下水文地质钻探及放水试验技术查明了会宝岭铁矿-410m~-760m标高井筒施工中出水点位置、岩性特征、水压、地下水导水通道及补给来源等水文地质成果;根据放水试验成果计算各涌水段水文地质参数,开展井筒施工涌水量预测,为井筒施工提出防治水建议,并为深部矿体开采提供重要的水文地质资料,也为沉积变质岩型铁矿床深部探水技术进行了讨论。In this paper,underground hydrogeological drilling and dewatering testing techniques were used to identify hydrogeological results,such as the location of water outlet points,lithological characteristics,water pressure,groundwater diversion channels and supply sources,during the construction of the shaft at an elevation of-410m to-760m at Huibaoling Iron Mine.The hydrogeological parameters of each water inflow section were calculated according to the dewatering test results,and the water inflow predition was carried out,so as to put forward water prevention suggestions for the shaft construction.The research results provide important hydrogeological data for the deep ore body mining,and a further discussion for the deep water exploration technology for the sedimentary metamorphic iron deposit.
