| 摘 要： | 白腊坪煤矿K_(13)缓倾斜薄煤层系三迭系煤层,平均厚度为1.0米,其上直接赋存一层8.0米厚的坚硬顶板。本文用薄板理论研究其顶板的应力分布规律,并且用最大拉应力强度理论推导出顶板初次及周期来压步距的理论计算式。应用该理论计算式对现场实施来压预报获得了成功。实践证明,用薄板理论研究薄煤层坚硬顶板的应力分布是合理的,对于生产现场具有十分重要的意义。

| Abstract: | In this paper, the stress distribution of the roof has been studied by use of thin plate theory, and on the basis of maximum stress theory, the formulas for first roof pressure and periodic roof pressure have been derived. During the field test, the writers have succeeded in prediction of pressure in use of the formulas. |
