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 roof of the main coal seam in Xieqiao Mine as the research object and combining with the previous research results, the roof lithology and type in this area are summarized and summarized. On this basis, the depositional environment of roofs 13-1, 11-2 and 8 # was analyzed. The results show that the lower soft upper hard roof is an ideal roof type, which accords with the general law of rock development and is conducive to the roof control and management. Different sedimentary environments formed different rock formations, and the sedimentary units also showed obvious differences in the vertical direction.
