以南阳煤矿3号煤层为例，依据其井田水文地质条件及防治水措施实施情况，对矿井水患类型进行分析，将矿井合理划分为可采区、缓采区及禁采区3个区域，针对各区的水害类型制定相应的防治水措施，并明确了矿井“三区”转换条件，提升了矿井防治水工作水平，为保障煤矿安全高效开采提供技术依据。

 Taking No.3 coal seam of Nanyang Coal Mine as an example, according to the hydrogeological conditions of the field and the implementation of water prevention and control measures, the types of mine water disaster were analyzed, and the mine was reasonably divided into three zones: recoverable area, slow mining area and prohibited mining area. The corresponding water prevention and control measures were formulated for the types of water disasters in each zone, and the conversion conditions of the 'three zones' of the mine were clarified, which improved the level of mine water prevention and control work. The study provided technical basis for ensuring safe and efficient mining of coal mines.
