【摘要】 借助山西潞安集团东盛煤业已有地质和水文地质资料，综合分析了该矿9+10号煤层的水文地质条件，采用理论公式法计算确定了9+10号煤层导水裂缝带最大发育高度为70.22 m，认为9+10号煤层的主要充水水源和水害类型为老空水、顶板水、大气降水，最主要的水害类型为老空水，并针对3种主要水害类型分别提出了水害防治建议。更多还原

【Abstract】 Based on the existing geological and hydrogeological data of Dongsheng Coal Industry, the geohydrologic conditions of No. 9+10 coal seam in this mine were comprehensive analyzed, and the maximum development height in water flowing fractured zone of No. 9+10 coal seam was calculated by the theoretical formula method, which is 70.22meters. The water of old mine, roof water and atmospheric precipitation are considered to be the main water filling sources and water damage types, of which the water of old mine is the most important type, and the suggestions for water disaster prevention and control aiming at the three main water disaster types are proposed.更多还原
