Abstract Based on the hydrogeological conditions of No.2 coal in No.10 mining area of Caocun Mine, the water filling conditions of No.2 coal in No.10 mining area of Caocun Mine were investigated, and the water outburst risk of No.2 coal roof and floor in No.10 mining area of Caocun Mine was analyzed. When the roof water conduction fracture zone formed by No. 2 coal seam mining communicated with the Quaternary gravel aquifer, the degree of roof water damage would increase. Based on the water outburst coefficient of Ordovician limestone in No.2 coal floor, the water outburst risk area of No.2 coal floor in No.10 mining areas was divided to guide the water prevention and control in the process of No.2 coal mining in No.10 mining areas.
