摘　　要：基于补连塔煤矿12407工作面煤层赋存特征,运用UDEC数值模拟软件建立二维地质模型,分析了该工作面导水裂隙带的发育规律。可以预测采空区上覆岩层的损伤程度,并提前采取措施,可防止工作面溃沙、透水和保护地表植被。Based on the seam deposit features of 12407 coal face in Bulianta coal mine,2D geological model of the coal face was established by using the UDEC software, and analyzed the development law of water flowing fracture zone at the coal face. That can forecast damage extent of the overlying rock in different mining height in the mined-out area,and can take measures to prevent to sand inrush and water inrush at the coal face and protect plants on the surface.
