摘　　要：以华亭大柳煤矿4煤综放开采涌(突)水为例,通过覆岩关键层位置研究导水裂隙带发育高度。结合离层水形成条件,分析区域离层水形成层位,并通过水质化验验证,确定了工作面涌(突)水水源,为华亭矿区乃至鄂尔多斯盆地较薄厚煤层开采防治水设计及措施制定提供了重要参考价值。Taking the water inrush case in top coal caving in Huating Daliu coal mine No. 4 coal seam,the paper studies the height development of water- flowing fractured zone according to key strata position,analyzes the regional separation layer water combining with its forming conditions,and determines the source of working face water inrush according to water quality test,so as to provide references for water prevention and control design and measures in the development of thinner thick coal seam mining in Huating mining area even the Ordos Basin.
