摘　　要：采用相似材料物理模拟实验的方法,对东北某矿特厚煤层顶板导水裂隙带的发育高度进行了探讨。结果表明:该矿特厚煤层顶板导水裂隙带发育高度为508 m,证明煤层在回采过程中,导水裂隙带将会波及到上覆第四系主要含水层,极易导致上覆第四系主要含水层中的水分从裂隙通道进入井下,从而给矿井带来水害威胁。By using similar material physical simulation experiments,the development heights of water induced fractured zones in thick coal seam roof are discussed. The results show that the height of water flowing fractured zone in roof of very thick coal seam in block coal mine is 508 m, the coal seam is proved to be in the process of mining, the water flowing fractured zone will spread to the overlying quaternary main aquifers, extremely easy to cause the overlying quaternary aquifer mainly in water from the fractured channel into the mine to bring flood threat to the mine.
