覆岩体内移动变形及离层特征

Movement,Deformation and Bed Separation Features of Mining-Affected Overburedn.

采动覆岩体内的移动变形与地表的移动变形本属一个问题的两个方面，长期以来地表的实际观测资料较多，在理论分析和工程应用方面积累了不少经验，而覆岩体内的移动变形由于观测条件的困难，实际观测资料较少。但是，随着生产技术的发展（如井筒煤柱的开采、覆岩离层带注浆充填减少（减缓）地表沉陷技术等），覆岩体内的移动变形规律的研究越来越显示出其重要性。本文阐述了作者近期对覆岩体内移动变形及离层特征的一些再认识。

ecause of the observation diffculties,limited actually-observed data relation to displacement and deformation of mining-affected overburden are available.However,with the development of mining technologies,such as shaft pillar extraction and high-pressure grouting in zones of the overlying strata experiencing bed separation for reduced ground subsidence,etc,the study of the law governing the movement and deformation of overburden has become ever-increasingly important.The paper also sheds light on some of the author's insight into the characteristics of movement and deformation of rock mass in the overburden.
