摘　　要：为了研究采空区积水对下组煤开采的影响,以大阳泉煤矿3#煤采空区积水情况及地质条件为背景,通过计算冒落带、导水裂隙带高度和采空区积水区域底板的破坏深度,分析积水区域构造的导水性,判断老空水对下组煤采掘工作造成的影响,为正确处理老空水害,保证矿井安全生产提供依据。In order to study the impact of goaf water on the lower coal group mining,taking goaf water situations in Dayangquan Coal Mine No.3 coal and its geological conditions as background,the paper estimates the impact of goaf water on the lower coal group mining by calculating the height of caving zone,the water flowing fracture belt,and the damage depth of goaf water area floor,and analyzes the water flowing characteristics,then provides the basis for correctly dealing with the goaf water and ensuring safety in mine production.

关 键 词：采空区积水 导水裂隙带高度 底板破坏深度 地质构造
