Abstract: This paper took the prevention and control of roof water damage in No.2 coal seam of Jinxinda Mine as the research background. Considering the topography, coal seam occurrence characteristics and mining technical conditions of the mining area, the spatial occurrence structure and groundwater characteristics of aquifer and aquiclude in the process of coal seam mining were analyzed. The types and basic characteristics of mine water damage were clarified. A variety of measurement methods were used to determine the stable height and maximum height of the water conduction fracture zone, and the dynamic change law of the water conduction fracture zone was analyzed to guide the safe production of coal mines.
