确定煤层顶板导水裂缝带高度可为顶板防治水、采掘工程布置、防水煤柱留设以及瓦斯抽采设计提供依据。采用井下仰孔注水测渗漏法，实测山西西山煤田镇城底矿8煤导水裂缝带高度为57.98 m，其中冒落带高度16.72 m，裂隙带高度41.26 m。依据实测结果并收集了8个矿综采一次采全高中硬覆岩下导水裂缝带高度数据，利用数理统计回归分析的方法，得出了适用于综采一次采全高中硬覆岩下导水裂缝带高度计算的经验公式，并与《煤矿安全规程》中相应经验公式进行对比分析，结果表明，该公式适用性好，而《煤矿安全规程》中有关公式应用于中厚煤层综采一次采全高开采条件预测，其误差较大。

Setting the height of the water conducting zone in roof can provide the basis for prevention and control of roof water, mining and excavation layout, leaving the water prevention coal pillars, design of coal gas drainage. Taking No.8 seam in Zhenchengdi mine, Xishan as a study object, using water injection leakage measurenment method in overhead borehole, the height was 57.98 m, the falling zone height was 16.72 m and the fractured zone height was 41.26 m. Based on observation result from 8 mines in the similar conditions, empirical formulas of wa-ter conducting zone height for fully mechanized mining face were obtained by statistical regression analysis. The contrastive analysis of the corresponding formula in"coal mine safety regulations"was carried out. The result show that the empirical formula has good applicability, formula in"coal mine safety regulations"has relatively large er-ror when applied in prediction of the mining conditions for mining height of fully mechanized mining in median thick seam.
