| 摘 要： | 本文利用弹性理论推导了煤层底板任意点的应力计算公式。提出了通过计算岩石的强度指数来预计煤层底板的破坏深度。依据底板破坏深度与承压水的“原始导高”的关系预测煤层底板突水的可能性,并以现场实测数据验证了这种计算方法的可靠性。图5,表2,参考文献2。

| Abstract: | Using the elastic theory,the author has derived the formula of the stress calculation in the seam floor, and advances that the failure depth of floor can be estimated by calculating the strength index of rock. There is a possibility in the seam floor according to the relation between the failure depth of floor and the initial raising height of pressure water and it can be confirmed by the in-situ data.
