| 摘 要： | 基于大量野外调查和巷揭情况，提出了陷落柱塌落前的岩体致塌破坏物理模型和两种致塌破坏结构，揭示了节理面在岩体致塌中的重要作用；从岩体结构角度阐述了由陷落作用形成的围岩构造；初步划分陷落柱的充填类型有：泥石浆型充填、顶冒武堆积、开放水体堆积；并讨论了陷落柱的堵水和活化突水问题。

| Abstract: | Based on a great deal of field investigation and observation in coal tunnel,the physical model and its two types of rockmass texture are advanced. Which causes fail in rockmass collapse before sinking in. The study reveals the significance of jionts in rockmass collapsing. Colllapse structures in surrounding rock are explained in view of rockmass mechanics. The pillar's filling formation types are preliminarily classified, i. e.,mud breccia fliud. roof fall breccia and open water body accumulation. And the pilllar plugging and activation cause of watel bursting are discussed. |
