单井稳定流抽水试验是目前煤炭勘探中获取水文地质参数、查明水文地质条件的主要方法之一。由于其获取的水文地质参数相对于非稳定流抽水试验简单直接而被广泛应用，但所计算的含水层渗透系数比实际往往偏小，且易忽视对水位恢复资料的分析研究与利用。通过对安徽淮南、淮北煤田近10年来水文地质勘探单孔稳定流抽水试验资料的分析与研究，论述了单井稳定流抽水参数计算的过程和存在的不足，强调了绘制水位恢复曲线的作用，提出了单井稳定流抽水渗透系数计算结果的采用方法和建议。进而使井田水文地质条件评价、矿井涌水量预测更加客观、真实。

The single well steady pumping test is one of major methods to acquire hydrogeological parameters and identify hydrogeologi-cal condition. In respect to the unsteady pumping test, its hydrogeological parameter acquiring is simple and direct, thus widely used. But its computed aquifer permeability coefficient sometimes is on the small side, and easy to neglect the analytic study and usage of wa-ter level recovery data. Through hydrogeological exploration single well steady pumping test data analysis and study in the Huainan and Huaibei coalfields, Anhui over past ten more years, discussed single well steady pumping test permeability coefficient computation pro-cess and existed insufficiency;emphasized the function of water level recovery curves, put forward single well steady pumping test per-meability coefficient computed results utilization methods and suggestions. And then make the minefield hydrogeological condition as-sessment and mine inflow prediction more objective and true.
