摘　　要：煤层顶板的稳定性是影响煤层回采工作安全最重要因素之一。根据大量钻孔和矿井生产资料,研究了木城涧矿侏罗系煤田主采十槽煤层顶板工程地质特征。结果表明:十槽煤顶板岩性均以粉砂岩、细砂岩为主,局部见泥岩;裂隙都较为发育,顶板破碎;顶板类型以稳定和中等稳定为主。该评价结果有助于该矿加强不同区域煤层顶板的管理及安全生产工作。The stability of seam roof is one of the most important factors that influences the safety of coal extraction . Based on the drilling and mining materials, studies on the roof geological condition of No. 10 coalseam in MuChengJian Mine of Beijing are carried out, then by the evaluation of seam roof through comprehensive index method, Which conclude that the main lithology of seam roof are siltstone and fine sandstone with many contin- uous structures and the main stability types of seam roof are stability and middle stability. The results are helpful in enhancing the management of different coal roof and salty production .
