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。
In order to study the development of water-conducting fractured zone, numerical simulation and simulation of similar materials were carried out based on the geological conditions of 12305 working face of a mine. Within a certain height of the overlying strata, the development of rock fractures between the mining boundary and the re-compaction zone is the most developed, leading to the formation of a water-conducting fracture zone. According to the calculation results of empirical formula, it is concluded that the height of water-conducting fracture in this working face is about 45 m, which provides a reference for the adjacent mine.
