摘　　要：为了研究泵房吸水井系统布局对围岩稳定性的影响,本文运用三维有限差分数值计算软件FLAC-3D,结合鹤煤九矿-420m水平泵房吸水井系统的传统设计和集约化设计2种布局方案进行了数值模拟,从巷道开挖后的围岩位移以及塑性区分布等多个方面进行了分析。结果表明,传统吸水井布局的岩柱尺寸对围岩的变形有一定影响,岩柱尺寸越大,围岩受影响范围越小,从总体上来说,集约化设计的泵房吸水井系统布局要优于传统设计。The finite difterenee sot＇tware, FIAC- 3D, is used to study the influence of system layout on sur- rounding rock stability. The traditional design and intensive design of - 420 m pump room system in the ninth mire, Hebi Coal Industry Group, is simulated and deformalion during pumping and absorbing well is studied. The resuhs show that the stability of smTounding rock is itd]ueneed by the rock pillar. The greater the size of roek pillar is, the smaller the deibrmation of surrounding rock is. The intensive layout is prior to the traditional design in absorbing well of pump room system on the whole.
