摘　　要：导水裂隙带是保水采煤研究与工程实践的重要参数,也是科学预测矿井涌水量的重要参数之一,尽管已有一些经验公式,但由于各矿井地质环境条件的差异,导水裂隙带发育高度很难用经验公式准确预测。因此,我们在榆神矿区榆阳煤矿施工了两个钻孔,根据冲洗液消耗量、岩心破碎程度、井中水位等指标,综合确定了榆神矿区榆阳煤矿2304综采工作面导水裂隙带高度,实测了综采条件下导水裂隙带发育高度。Water flowing fractured zone is an important parameter for the research and engineering practice of water-preserved mining and the scientific prediction of mine inflow. It is very difficult to predict accurately by empirical formula,because of the differences of geological conditions in different mine. By operating two boreholes in Yuyang Coal Mine,according to the indicators of consumption of flushing fluid,core crushing degree and well water level,the height of water flowing fractured zone of №2034 fully mechanized mining face is determined.
