摘要
通过对刘桥矿区6煤层顶板岩层的岩性和岩性组合结构的分析,确定了不同区域的稳定性情况。该评价结果有助于在煤矿开采过程中加强不同区域煤层顶板的管理及科学地指导工作。
Through analysis of lithologic character and composite structure of roof rock of No.6 coal layer in Liuqiao Coal Mine, the stability of roof rock in different zones are assessed.The assessment is helpful for improving monitoring and control of roof rock stability during coal exploitation.
