摘　　要：为研究煤层采空区上方导水断裂带高度,检验计算机模拟在导水断裂带高度计算中的效果,以古窑煤矿1202(1)回采工作面为研究背景,通过现场调查、理论分析计算、FLAC^(3D)数值模拟以及现场钻孔实测得出了1202(1)回采工作面导水断裂带高度,运用"上四带"理论得出导水断裂带高度为60 m,与实际测量数据62.18 m误差仅为3.51%,运用FLAC^(3D)数值模拟得出的导水断裂带高度为58 m,误差为6.72%,与实测结果相符合。In order to study the height of water flowing fractured zone above goaf, test the effect of computer simulation in analyzing the water flowing fractured zone in coal, taking the 1202（1） working face of Guyao Coal Mine as the research background,through field investigation, theoretical analysis and calculation, FLAC^（3D）numerical simulation and field drilling test, it concludes the height of water flowing fractured zone of 1202（1）working face： using the＂upper four-zone＂theory, it is concluded that the height of water flowing fractured zone is 60 m and the error with the actual field measurement of 62.18 m is only 3.51%; using FLAC^（3D） numerical simulation, it is concluded that the height of water flowing fractured zone is 58 m and the error is 6.72%, which is consistent with actual field measurement result.
