| 摘 要： | 将煤层底板至含水层间承载能力最大的一层岩层看作起阻水作用的关键岩层（简称关键层），并把它简化为薄板，利用板的理论解确定该岩层的破断跨距，用以评价底板突水的危险性．实例分析表明，这种预测突水危险性的方法是简明有效的．

| Abstract: | The stratum with the largest bearing capacity between coal seam and aquifer is regarded as the key stratum in preventing from water inrush,and it is simplified into a thin plate. Its fracturing span is determined by the plate theory, and is used to appraise the risk of water inrush from floor. The analyses of real examples show that the method is the simple and efficacious. |

| Keywords: | Water inrush from floor key stratum thin plate |
