In view of the abnormal water inflow in No.14104-1 mining face of Majialiang Coal Mine, in order to find the water source and water conducting channel of the working face, through the construction of exploration drilling, combined with the geological and hydrogeological conditions of the water outlet area, the water level, water quality and water conducting channel of the aquifer were comprehensively analyzed. The mechanism of Ordovician limestone water outburst was studied, and the grouting control of the water channel was carried out. Combined with the grouting situation and the change of water inflow, it was finally determined that the water source was Ordovician limestone water and the water channel was fault fissure conducting water. Through the grouting control of the water conducting channel in the floor aquiclude of the water inflow area, the purpose of plugging the water conducting channel was achieved, the risk of water outburst was reduced, and the safe mining of the working face was realized.
