| 摘 要： | 本文把煤层底板空间剩余完整岩体作为矩形薄板体，根据弹性平板理论，应用变分方程计算板的位移，引用Ｔｒｅｓｃａ最大剪力破坏准则，推导出底板隔水层空间剩余完整岩体的极限抗水压值公式，判定与评价其抗水压能力。该理论分析与应用参数选择较接近于工作面的实际，具有实用意义。

| Abstract: | The remaining intact rock of floor is considered as a thin rectangular plate,and thedisplacement of the plate is determined by the variation equation,based on the theory of elastic plate. The formula of critical value of anti-hydropressure for the remaining intactrock of floor is developed with Tresca criterium of maximum shear failure.The theoriticalanalysis and selection of parameters in the paper are of practical significance. |

| Keywords: | coal floor critical value of anti-hydropressure |
