Freezing method was adopted in the initial design of inlet air vertical shaft of some mine, in order to shorten shaft construction period and reduce the cost of construction, the original plan was change to normal construction, pre-grouting technology was adopted crossing aquifer in shaft construction, with back wall grouting to water position of shaft wall after shaft going down. The practice showed good water control effect, provided experience for vertical shaft water prevention and control under similar condition.
