Abstract：In the period of constructing the bedrock section of East Air Shaft in Fenghuangshan Iron Mine ,water appears in depth at 646 m of mine. According to the actual field and the exposed situation of rock ,the following water shutoff technology was taken. Firstly ,strengthen rock plug and detect wa‐ter in local.Then ,pour slurry blocking pad.Lastly ,carry out pre‐grouting with detecting water at the same time. The result is good ,and the aquifer is through smoothly.It also provides a good condition for the borehole digging puzzle.It has a reference value to pit shaft building with similar hydrogeologi‐cal condition.
