摘　　要：研究关键层的复合效应对深入揭示关键层在采动覆岩中的控制机理具有重要推动作用。本文进一步明确了关键层复合效应的概念 ,系统分析了关键层复合效应对关键层破断、采场来压、岩层移动、采动裂隙分布以及地表沉陷的影响。The comprehensive study of complex effect of key stratum plays an important role in understanding control mechanism of key stratum in overlying strata within mining influence. This paper explains the concept of complex effect of key stratum, and analyzes relation between the complex effect and rupturing of key stratum, mining stress abutment, movement of overlying strata, distribution of strata cranny as well as surface subsides.

关 键 词：采动岩体 关键层 砌体梁 复合效应 岩层控制
