摘　　要：通过分析鲍店煤矿浅部区域第四系松散含水层水文长观孔历年水位数据,绘制出水位与时间的变化关系曲线,分析了研究区域内水位变化特征,建立了水位与时间的回归方程,对未来几年内水位变化趋势进行了预测。使用Surfer 8.0软件绘制了矿区多年不同时间段地下水水位曲面,以此推测了水位空间变化趋势。综合分析两种方法得出的结果可以看出,第四系下组含水层水位逐年下降,富水性趋于减弱,松散含水层有疏干的可能性。水位降幅初期比较大,后期比较小,矿井开采是水位下降的主要影响因素之一。提出了妥善处理松散含水层与矿山开采之间的关系,实现高效采煤及水资源有效利用的相关对策。By analyzing the water level data of hydrologic long-observation holes in the Quaternary loose aquifer of shallow region in Baodian Mine over the years, the change curve of water level and time was drawn up, the variation characteristics of water level in the study area were analyzed, the regression equation of water level and time was built, the variation trend of the water level in the next few years was predicted. The groundwater levels in different time periods in many years were drawn up by using Surfer 8.0 software so as to infer the space variation trend of water levels. It could be seen from the comprehensive analysis of the results obtained by two methods that the water level of the Quaternary water-bearing layer declined year by year, its water abundance tended to weaken, and the loose aquifer had the possibility of dewatering. Downrange of groundwater was big in the initial stage and late became relatively small, underground mining was one of the main factors of water lowering. Finally, the relevant measures for properly handling the relations between the loose aquifer and mining, realizing the efficient coal mining and the effective use of water resources were proposed.
