In order to provide macro guidance for the exploration and development of coal resources and water disaster prevention and control in Tongzi area, seven coal-bearing tectonic units were divided according to the main structural forms and coal seam occurrence rules of coal mine distribution areas in Tongzi area. And the coal seam occurrence conditions of each unit were summarized. It was pointed out that the thickness of coal measures strata, the number of minable coal seams and the total thickness of coal seams in Tongzi area showed a decreasing trend from southwest to northeast. According to the occurrence state of coal seams in each structural unit, the influence of main water filling sources such as roof Changxing limestone water, floor Maokou limestone water and goaf water on coal mining in each unit was pointed out respectively, and then the main water prevention and control measures for coal mining in China were put forward.
