摘要: 利用煤层底板在采动过程中岩层内部参数值在突水前夕的变化来分析、预测底板突水的可能性,方法是数值模拟与现场测试及两者的结合,综合评价煤层底板的突水可能性。本文着重介绍了该方法的原理、仪器及工作方法。Abstract: Making use of the changes of inferior parameters of floor rocks with coal mining, the possibility of water inrush is analyzed and forecasted, which include numerical simulation and in-situ measurement. The double are combined to give comprehensive evaluation of water inrush possiblity. The paper emphasizes the fundamentals, device and work method of the means.
