| 摘 要： | 根据大量钻孔资料和矿井生产资料，对研究区二叠系５、６煤顶底板的岩性分布和岩石力学性质进行了初步的研究与探讨。５煤顶底板以泥岩分布最广，６煤顶底板砂岩、粉砂岩和泥岩均有较大分布。砂岩稳定性较好，粉砂岩次之，泥岩较差。

| Abstract: | A preliminary study has been undertaken on the lithology and mechanics of the roof and floor rocks of the Permian seams 5 and 6 in the target area by using considerable borehole and production data.It is considered that the roof and floor of seam 5 are in poorer steadines,where mudstone prevails,and the roof and floor of seam 6 in better steadiness,where sandstone dominates. |
