摘　　要：针对破碎厚煤层工作面端面顶板的岩层结构特点,构建了工作面端面顶板的结构模型。运用块体理论,在分析"块体"结构顶板失稳破坏形式的基础上,又对破碎厚煤层工作面端面顶板失稳破坏进行了力学分析,进而揭示了该类型工作面端面顶板漏冒的机理和动态破坏过程。通过对晋煤集团赵庄煤业公司3307破碎厚煤层工作面端面顶板稳定性的分析,给出了防治工作面端面顶板漏冒的主要措施。For end-face roof structure characteristic of mining face in soft and thick coal-seam, structure mechanical model of end-face roof was set up and roof instability was analyzed by block theory. The roof falling mechanism and dynamic failure period of this type face was discovered. Main countermeasures of preventing end-face roof falling were present by analyzing end-face roof stability of 3307 min- ing face, Zhaozhuang Colliery of Jincheng Coal Group.
