摘　　要：以谢桥矿区主采煤层顶板为研究对象,并结合前人的研究成果,对该区顶板岩性和类型进行了统计与总结。在此基础上,分析了13-1、11-2和8#煤顶板的沉积环境。结果表明:下软上硬型顶板是一种理想的顶板类型,符合岩层发育的一般规律,有利于顶板的控制和管理。不同的沉积环境形成不同的岩层,纵向上各沉积单元也表现出明显的差异性。Taking the main coal seam roof in Xieqiao Mining Area as research object, statistics and summaries of the roof lithologic fea- tures and type are carried out with previous research results. On this basis, sedimentary environments of 13 -1, 11 -2, and 8 coal seam roof are analyzed. It is indicated that lower soft and upper hard roof is an ideal roof type which is in line with the general law of strata development and also conducive to roof control and management. Different rocks are formed in the different sedimentary environ- merits, and significant differences are also showed on the each sedimentary unit in the longitudinal direction.
