Abstract：In order to ensure the mining safety of 112121 working face in Xin'an Coal Mine, sectional target grouting technology was applied to reform the water-rich aquifer of working face floor, and reinforce the incomplete aquiclude. According to the grouting area situation and water inflow of the seam, the sub-region and sectional grouting was carried out to eliminate potential hazard in the working face, using clay cement slurry and cement-water slurry as grouting material. Practice has proved effectiveness of the grouting technology.
