摘　　要：以色连煤矿河床下煤层开采为工程背景,采用理论计算、数值模拟和现场实测相结合的方法,对2_(-2)上煤层覆岩导水裂隙带发育高度进行研究。观测及模拟结果表明,色连煤矿2-2上煤覆岩导水裂隙带最大发育高度73 m,为矿井防治水和保水采煤提供设计依据。Mechanized mining of buried coal seams beneath the riverbed in Selian coal mine as engineering background, application of theoretical calculation, numerical simulation and field measurement to research the height of water flowing fi＇actured zone of 2-2 upper coal, providing the basis for the design of prevention and treatment of mine water. ConsoLidated results obtained the largest growth height of water flowing fractured zone of Selian coal mine is 73 m.
