| 摘 要： | 根据地质条件对下组煤的底板破坏深度进行了理论计算并在此基础上运用突水系数法对底板突水情况进行了分析;应用离散元数值软件UDEC模拟了在薄煤层群采动应力和水压联合作用下底板的破坏规律和裂隙演化规律,得出底板破坏深度将达到41 m,底板突水可能性较大,应加强底板防治水工作。 |
| 关 键 词： | 承压水 薄煤层群 底板突水 数值模拟 耦合作用 |

| Abstract: | According to the geological condition,floor failure depth of lower coal group was carried out a theoretical calculation,and on this basis,floor water irruption condition was analyzed by water inrush coefficient method.The paper simulated destruction law and crack evolution law of the floor under the combined effects of thin seam group mining dynamic stress and water pressure by using discrete element numerical simulation software UDEC,and obtained that the floor failure depth would reach 41 m.It was likely to happen floor water irruption,and the water prevention work of floor should be strengthened. |
| Keywords: | confined water thin coal seams group floor water irruption numerical simulation coupling effect |
