摘　　要：针对煤矿充水含水层抽水试验Q—S曲线类型判别方法、Q—S曲线类型与水文地质特征关联的规律性进行分析,以开滦林南仓矿和东欢坨矿典型充水含水层历史抽水试验数据为研究基础,对比分析了曲度法、作图法和Excel趋势线法3种常用判别方法在Q—S曲线类型判别中的适宜性,以及典型充水含水层中抽水试验Q—S曲线类型与10 m降深单位涌水量。研究结果表明:曲度法适宜性较差,作图法与Excel趋势线法适宜性较好,两者的判别结果具有高度的一致性。In this paper, analysis was carried out on the discrimination methods of the Q-S curve types of the pumpingtests in mine water-filling and water-bearing strata and the relationship between the Q-S curve types and the hydro-geologicalcharacteristics of the water-filling and water-bearing strata. By taking the historic data obtained in pumping tests in the water-filling and water-bearing strata in Linnancang and Donghuantuo Coal Mines of Kailuan Group Co. , Ltd. , as the research bases,comparative analysis was made on the applicability of the curvature method, mapping method and Excel trend line method in thediscrimination of the Q-S curve types, the Q-S curve types of the pumping tests in the typical water-filling and water-bearingstrata and the unit water inflow of 10 m drawdown. The research results showed that the applicability of the curvature method wasbad and that of the mapping method and Excel trend line method was good, and the discrimination results were highlyconsistent.
