Abstract It was one of the main causes of mine water damage accidents that the surface accumulated water and atmospheric precipitation poured into the underground through ground fissures formed by coal mining. By analyzing the relationship between water inflow and atmospheric precipitation, coal production and cumulative coal production in Xiegou Mine, it was concluded that the water inflow of Xiegou Mine was mainly affected by surface atmospheric precipitation at the present stage. By filling ground fissures on the surface and building drainage channels to discharge surface water, the mine water inflow was reduced and the mine safety production was ensured.
