为系统性认识矿井各类水害问题，规范化管理矿井防治水工作，国家矿山安全监察局于2022年6月将针对老空水防治的“三区”管理工作推广到顶板水害、底板水害以及构造水害等更多水害类型中。然而各地煤矿在防治水“三区”划分过程中暴露出水害致灾因素和水害治理情况等与划分标准结合不紧密，并且技术上未针对不同煤层和采区进行区别划分，同时划分区域范围和划分结果的规范性和时效性存在不统一。据此，结合防治水“三区”划分的目的，对比了新“三区”划分与老空水“三区”划分的异同，明确了以水文地质条件勘查程度、水害隐患分析、水害治理情况为要素的划分原则，理清了“三区”划分的技术路径；结合我国常见的5种煤矿水害类型特征，提出了不同类型水害的划分方法，即：地表水害应根据井田内地表水体的分布发育特征以及大气降水、滑坡等地质灾害对开采的影响程度等进行划分。顶板水害应根据导水裂隙带范围内是否存在富水性强或者富水性中等静储量丰富含水层、松散含水层等对开采造成威胁进行划分。底板水害应根据煤层带压开采区域底板隔水层厚度与矿压破坏带深度之间的关系以及底板突水系数大小进行划分。老空水害应根据矿井及周边矿井老空积水分布范围、积水量情况进行划分，构造水害应根据井田内断层、陷落柱、溶洞等地质构造和不良地质体的富水性、含水性、与水源导通情况进行划分；总结了划分工作的要点和难点，即：明晰划分时空范围、综合分析划分标准、明确“三区”管理职责、动态转换划分结果等；在此基础上，选择水害类型多样和水文地质条件复杂的典型煤矿井，遵循划分原则，根据划分标准，分煤层、分采区划分了可采区、缓采区、禁采区，并加以详细的解释说明；阐明了开展“三区”划分工作具有提升综合探测水平、强化预测预报能力、找准水害治理方向的水害防治意义，以期指导和规范我国煤矿防治水“三区”划分工作。

In order to systematically understand the various types of water hazards and standardize the management of water prevention and control work in coal mines, the National Mine Safety Administration in June 2022 extended the “three zones” management methodology for old goaf water prevention and control to more types of water hazards, such as roof water, floor water, and structural water. However, in the process of dividing the “three zones” of water prevention and control in coal mines, it is revealed that the water damage causing factors and water damage management situation are not closely linked with the division standard, and that technically different divisions are not made for different coal seams and mining areas, and there are inconsistencies in the scope of the division area, and the standardization and timeliness of the division results. Accordingly, combined with the purpose of water hazard prevention and control “three zones” division, compared the similarities and differences between the new and old “three zones” division work, this paper clarifies the degree of hydrogeological conditions survey, water hazard analysis, water hazard management as elements of the division principles, and determines the technical path of the division of the “three zones”. Combining the characteristics of five common types of water hazards in coal mines, the paper puts forward the division method of different types of water hazards, that is: surface water hazard should be divided according to the distribution and development characteristics of surface water bodies in the mining area and the degree of influence of atmospheric precipitation, landslides and other geological disasters in mining. The roof water hazard should be divided according to whether there is a strong water-rich aquifer, a medium water-rich but hydrostatic reservoir-rich aquifer, a loose aquifer. The floor water hazard should be divided according to the relationship between the thickness of the floor water barrier and the depth of the floor mine pressure damage zone in the coal seam pressure mining area, as well as the size of the floor water inrush coefficient. The old goaf water hazard should be divided according to the distribution range and amount of water in the mine and the surrounding mines. The structural water hazards should be divided according to the water-richness, water content, and water source conduction of geological structures and bad geological bodies such as faults, trap columns and caves in the mining area. The key points and difficulties of the division work include the clear division of time and space scope, the comprehensive analysis of division standards, the clear management responsibilities for the “three zones”, and the dynamic transformation of division results. On this basis, typical coal mines with various types of water hazards and complex hydrogeological conditions are selected as case studies. Following the principle of division, according to the division standard, the mineable zone, the slow mining zone and no-mining zone are divided by the method of separating coal seams and mining areas, and detailed explanations are given. The significance of carrying out the division of the “three zones” for water hazard prevention and control is clarified, which can enhance the comprehensive detection level, strengthen the prediction ability, and identify the direction of water hazard management in order to guide and standardize the division of the “three zones” for water prevention and control in the coal mines of China.
