| 摘 要： | 根据大倾角煤层采场矿压显现特点 ,对采场顶板岩层的运动、破坏形式进行了研究 .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 . |
| 关 键 词： | 大倾角煤层 直接顶 砌体结构 矿压显现 |

| Abstract: | Based on the strata behaviors of steep coal seams, the forms of roof breakage and movement were studied. 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. The stability criteria of the arch structure were discussed as well. |
| Keywords: | steep coal seam immediate roof voussoir beam structure strata behavior |
