摘　　要：为了研究导水裂隙带的发育规律,依据某矿12305工作面地质情况,进行了数值模拟及相似材料模拟研究。在上覆岩层的一定高度内,开采边界与重新压实区之间岩层裂隙发育最为充分,形成导水裂隙带。结合经验公式计算的结果,得出该工作面的导水裂隙高度为45 m左右,为相邻矿井提供了一定的参考依据。According to the geological conditions of working face 12305 in a mine, use two methods, numerical simulation and similar material simulation, to study the development regularities of water- flowing fractured zones.The rock fractures between the mining boundary and the compaction area again makes the greatest development lead to water-flowing fractured zones in a certain height of overburden. Combined with the results of the empirical formula calculation,it is concluded that the working face water-flowing fractured height is 45 m or so,provides certain reference basis to the adjacent mines.
