摘要(Abstract)：

为对导水裂隙带发育高度进行高精度定量化全空间预测，提出了一种将多元回归分析与波形指示反演相结合的导水裂隙带发育高度预测方法。分析了采高、煤层底板埋深、工作面跨度以及硬岩比例系数与导水裂隙带发育高度之间的内在联系，并通过多元回归分析建立了黄陇煤田导水裂隙带发育高度预测数学模型，模型相关系数为96.7。利用波形指示反演精细解释了煤层上覆岩层的岩性展布形态，并基于钻孔数据验证了解释成果。基于解释成果结合煤矿开采设计参数应用预测数学模型实现了导水裂隙带发育高度全空间精细刻画。钻孔DT1和DT2通过地面钻孔分段注水试验和窥视方法，测得导水裂隙带发育高度分别为327.7 m和197.85 m。预测结果与实测相比，误差均小于10 m。
