摘　　要：为了准确判断在上行开采期间下部煤层的主要充水水源,需要对下部煤层回采产生的导水裂缝带发育高度进行预测。在对矿井水文地质条件分析的基础上,利用相似材料模拟实验对下部煤层的导水裂缝带发育高度进行了预测,并结合煤层和含水层的空间关系,分析了下部煤层的主要水害威胁。结果表明:下部煤层的导水裂缝带仅能够波及到其顶板含水层,上部煤层顶板含水层对其未构成水害威胁,并制订了相应的防治水措施。通过分析,利用相似材料模拟对下部煤层的导水裂缝带发育高度进行预测,其成果可以作为上行开采条件下开展防治水工作的依据。It is necessary to predict the development height of the water flowing fractured zone produced in the lower coal seam extraction in order to accurately confirm the main water filling source during the ascending mining. Based on the analysis of the hydro- geological conditions in the mine,the prediction was carried out on the development height of the water flowing fractured zone in the lower coal seam through the similar material simulation experiments,and analysis was made on the main water flooding threat in the lower coal seam according to the space relation of the coal seam and aquifer. The results showed that the water flowing fractured zone in the lower seam can only spread to its roof aquifer,the roof aquifer of the upper coal seam did not constitute water flooding threat to it,and based on this research result,corresponding measures for water flooding prevention and control were formulated. Through analysis,prediction was made on the development height of the water flowing fractured zone in the lower coal seam with the similar material simulation,and this result can be used as the basis for carrying out water flooding prevention and control work under the condition of ascending mining.
