摘要
煤矿开采引起覆岩及地表沉陷的控制理论与技术研究是涉及全球性灾害学科的研究内容之一。笔者通过对采动覆岩破坏特征的分析，提出了覆岩破坏与移动的“竖四带”的分区模式；并在评述传统控制技术及效果的基础上，介绍了覆岩与地表沉陷控制的新技术——离层注浆技术的原理。
The theory and control technology for migration of roof strata and surface subsidence caused by mining operation are a part of the study of natural calamity all over the world. A from of 'Four Layers in Vertical Line in Rock' during the migrating process of over-loading is suggested through analyzing the natural characteristics of damaged roof strata. On the basis of evaluating the efficiency of traditional control technology,a newly developed technology, i.e filling the collapsed cavities with mud, is illustrated and the importance in its future application is predicted.
