In recent years, with the increase of mining depth, coal mines in mining process were threatened by water damage of Daqing limestone aquifer and Ordovician limestone aquifer in China. Faults, collapse columns, fracture zones and other structures were fully developed in the mine field, which became water outburst channels entering the working face.  The exploration and treatment of water conduction fractures and concealed structures by traditional underground drilling methods were difficult, time-consuming and dangerous. In view of this situation, the new means of ' surface regional control ' was used to grouting the leakage points in the drilling process, so as to achieved the purpose of early control and transformation. Therefore, the quality of grouting was related to the effect of control. This paper briefly analyzed the grouting effect test.
