摘　　要：在阐述覆岩离层注浆地表减沉机理研究背景及研究现状的基础上,通过对综合机械化煤炭开采过程中覆岩离层产生条件和机理、离层形成过程、机理的理论研究,建立覆岩离层充填开采力学模型,得出覆岩离层注浆地表减沉的主控因素,对注浆工程理论及实践的发展有良好的促进作用。Based on the elaborating of the study background and study status on surface subsidence mechanism of overburden separation grouting,through the theoretical study of the conditions and mechanism of overburden separation,the formation process and mechanism of overburden separation in the process of comprehensive mechanized coal mining,the mechanical model of overburden separation filling mining is established,and the main controlling factors of surface subsidence of overburden separation grouting are obtained,which has a good role in promoting the development of grouting engineering theory and practice.
