Abstract Aiming at the problem of goaf water accumulation in 303 panel of Sitai Mine, combined with panel hydrogeological conditions, the water prevention and control plan and grouting hole layout were determined. The specific grouting construction technology was analyzed and studied, and the grouting effect was verified by drilling method. The results showed that through the grouting sealing of 303 panel, the water accumulated in No. 14 303 panel could be effectively prevented inflow through three panel roadways, and the water damage in 303 panel was solved. The water level in the panel was stable, and the fund of 3.564 million yuan could be saved every year.
