摘  要:离层水害是一种罕见而危害严重的灾害形式,论文通过水文地质分析、相似材料模拟、数值模拟和冲击水压试验证实发生在淮北海孜煤矿的顶板次生离层水害的成因。针对灾害原因,采取了采动疏干的防治水方法,取得了满意的效果,确保了类似条件工作面开采的安全。The water disaster from the mine roof partings is a one of the rare and dangerous disasters. With the hydrogeological analysis, similar material simulation, numerical simulation and impact water pressure test, the paper confirmed the cause of the water disaster from the roof partings occurred in Haizi Mine of Huaibei. In accordance with the disaster cause, a water prevention and control method with a water drainage in mining operation was adopted and had obtained with satisfied results to ensure the mining safety in the coal mining face under the similar conditions.
