摘　　要：覆岩破坏高度研究是研究采动岩体地下水渗流规律的基本前提,也是解放水下压煤和保证矿井安全生产的重要步骤。文章将数值模拟与邻近矿区实测资料相结合,模拟分析了梧桐庄矿煤层开采导水裂缝带高度,为水下安全开采提供依据。Research on the height of overburden failure is a basic premise to study the law of groundwater seepage under overburden rock stratum, and also is the key to liberate the coal under water body and to ensure safety mining production. Hence, the paper uses combines measured data of nearby mine to simulate the maximum height of mining hydraulic conductivity fracture zone in 2^# coal seam of Wutongzhuang Mine, and the result will provide＇ a basis for safety mining under Yuecheng Reservoir.

关 键 词：水下开采 导水裂隙带 数值模拟
