Abstract In this paper, the hydrogeological conditions and mine water filling factors of No.2 mine in Sihe Coal Mine are studied. The hydrogeological conditions such as mine aquifer, aquiclude, mine field boundary and hydraulic connection are identified. The mine water filling factors such as water filling source, water filling channel and water filling intensity are analyzed. The mine hydrogeological types are divided to realize the clear hydrogeological conditions of the mine and the hidden disaster-causing factors of water damage. It provides a scientific and reliable basis for water prevention and control for mine mining, and ensures the efficient and safe production of No.2 mine in Sihe Coal Mine.
