1)immediate roof直接顶
1.It was point out that main roof can form the voussoir beam structures in the inclination, and immediate roof located at the middle\|lower section of a longwall face probably forms a voussoir arch structure with a small scale because of waste filling.提出了大倾角条件下老顶岩层在运动中易于形成倾斜砌体结构板大结构 ,直接顶岩层则因上段冒落矸石充填 ,在采场中下段形成砌体梁小结构 ,并探讨了中下段小结构平衡的极限条件和结构失稳形式 。
2.The main roof applies a given deformation on the immediate roof.根据砌体梁理论，上覆岩层破断以后仍可以形成能够承受载荷的稳定岩体结构，因此老顶通常以给定变形的方式作用于直接顶。
3.Deformation and failure features at different heights of immediate roof in working face are analyzed by using numerical calculation method.运用数值计算方法分析了采场不同高度直接顶的变形破坏特征，提出直接顶的“临界高度”（ｈｃｒ）概念，将直接顶按临界高度进行分类，指出当直接顶高度Σｈ ≥ｈｃｒ 时，不能单纯以顶板下沉量来判别顶板是否稳定，而要综合考虑端面顶板的稳定性。
