某煤矿北翼充填采区地层以奥陶系灰岩作为含煤地层基岩，其上覆岩层中第四系孔隙承压强含水层全区发育，研究充填开采后导水裂隙带发育高度对实现安全开采具有重要意义。本文以等效采高为基础，利用理论计算、数值模拟、相似材料模拟3种方法对某煤矿导水裂隙带发育高度进行预测，得出导水裂隙带高度分别为12.72，12.50，14.28 m。结果表明：3 种预测方法相比较具有良好的吻合性，对某矿井的水体下安全开采实际工程实践提供了重要的理论依据。

The layer of the North wing filling mining area in a certain coal mine uses the Ordovician limestone as coal-bearing strata rock, the Quaternary pore confined aquifer in the overburden is developed. Study the height of water flowing fractured zone after filling is significant to achieve safety mining. This study is based on equivalent mining height, using three methods of theoretical calculation, numerical simulation and similar material simulation to forecast the height of water flowing fractured zone in a certain coal mine, respectively. It is obtained that the heights of water flowing fractured zone are 12.72, 12.50 and 14.28 m, respectively. The result indicates that the three methods match well by comparison, and it provides important theoretical basis to mining engineering practice under water in a certain coal mine.
