Mine water inrush from rocky ground cracks is a major form of water inrush from the roof of shallow coal seams in gully areas, especially under heavy rainfall conditions, surface flooding poses a greater threat to the safety of mine production. In order to study the law of mine water inrush from rocky ground cracks in the gully under heavy rainfall conditions in shallow coal seam areas. Take a coal mine in the Carboniferous-Permian system in northern Shaanxi as an example. By predicting the flood flow in the surface gully under different rainfall conditions, summarize and analyze the development characteristics of surface cracks in different working faces, the calculation formula for flood flow of surface channel cracks in shallow coal seam mines is used to predict the water burst at different working faces. Comparing the calculation results of mine water inrush from rocky ground cracks with the actual mine water inrush from rocky ground cracks in surface gully of a certain working face, it is found that the calculated value and the actual water value are small, which can meet the forecast demand of mine water inrush from rocky ground cracks in surface gully. The research results provide a practical method for predicting the amount of mine water inrush from rocky ground cracks in shallow coal seam trenches in the valley area, which can more accurately predict the amount of mine water inrush from rocky ground cracks, which is of great significance to the prevention and control of mine water hazard caused by surface water in shallow coal seam areas.
