Abstract Mine water inflow would deteriorate the working environment of mining face, cause disasters, and seriously affect the mine production safety and the life safety of workers. In order to ensure the safe production of Sanyuan Coal Industry, the water inflow and each water filling factors in the mining process of No.3 coal seam were comprehensively analyzed. It was considered that the influence of atmospheric precipitation on mine water inflow was small and could be ignored. The yield and mining area had a certain impact on the mine water inflow, but the overall impact was not significant ; the mine water inflow was mainly affected by the water accumulation in the goaf. On this basis, it was proposed to strengthen the collection of basic geological data, use geophysical detection and drilling detection techniques to strengthen the detection of goaf water and other water prevention and control countermeasures, which laid a foundation for the safe production of the mine.
