Based on Chaochuan Mine Niuzhuang vice shaft wellbore water spray problem, low density, strong diffusibility of RSS polymer chemical water plugging material was adopted, combined with the low cost of cement grouting materials, shallow and deep hole crossing grouting was conducted. slurry infiltration water penetration, diffusion strata cranny achieved purpose of strengthening wellbore, blocking water, which reasonably solved Chaochuan Mine Niuzhuang vice shaft wellbore water spray problem. The water spray section water inflow was not more than 3 m3/h after treatment, the remain water was led out of treatment area through aqueduct, without water spray in shaft.
