| 摘 要： | 应用东北大学岩石破裂与失稳研究中心(CRISR)自主开发的F—RFPA^2D渗流与应力耦合分析系统，对煤层顶板随着开采的逐步进行，采动裂隙逐渐向上发展并最终与含水层连通，进而发生顶板突水的全过程进行了数值模拟，直观地显示了煤层顶板的变形、破坏过程以及渗流场在整个岩体的运移过程及其突水前后渗流场的变化情况，从而较好地揭示了顶板突水过程。 |
| 关 键 词： | 采动裂隙 顶板突水 数值模拟 |

| Abstract: | The whole process of water burst of roof, which results from cracks growing upwards and extending into aquifer in course of coal progressive mining, was simulated in this paper by Coupling System of Flow and Solid in Rock Failure Process Analysis (F-RFPA 2D), which is developed by the Center for Rock Instability and Seismicity Research of Northeastern University. It visually shows the deformation, failure process of rock strata overlying stope, the transfer of seepage field in rock strata and its change before and after water burst, so it is very useful for the design of stope and the prevention of water burst. |
| Keywords: | cracks caused by coal mining water burst of roof numerical simulation |
