Abstract: An iron mine infrastructure shaft -50 m level horse head Door and roadway are located in the cement-bearing limestone-bearing limonite layer.Because there is a riverbed in the upper part of the ore layer,the river water and water-conducting faults enter the mining area,causing the construction to be interrupted.In order to prevent and control the fault water guide,through the site investigation,the horizontal head horse head door and part of the roadway were sealed by gushing water by curtain grouting technology,and the water belt was quickly passed.It has achieved good results and provided reference for the construction of similar projects.

Key words: Shaft, Horse head door, Curtain grouting, Water zone
