为满足淮南矿区厚松散层下浅部煤层安全开采合理确定开采上限的需要，本研究通过经验公式法与回归分析得到的公式进行对比，获得符合本矿区地质条件和采煤方法的导水裂隙带发育规律及导水裂隙发育高度的预测公式。并与物理探测法和数值模拟法得到的结果进行比较分析，最终确定最合理的导水裂隙带高度。
為滿足淮南礦區厚鬆散層下淺部煤層安全開採閤理確定開採上限的需要，本研究通過經驗公式法與迴歸分析得到的公式進行對比，穫得符閤本礦區地質條件和採煤方法的導水裂隙帶髮育規律及導水裂隙髮育高度的預測公式。併與物理探測法和數值模擬法得到的結果進行比較分析，最終確定最閤理的導水裂隙帶高度。

To meet the need of the determination of safe mining upper limit of shallow coal seam under the thick loose coal bed in Huainan mining area,the empirical formula method and the regression analysis were compared,and then the developing rule of diversion fissure zone and the predicting formula about the development height of diversion fissure zone were got.Compared with the results obtained from the physical detection and the numerical simulation,the optimum height for the diversion fissure zone was determined.
