| 摘 要： | 在简述关键层理论的产生背景、发展历程与应用现状的基础上,分析了关键层理论应用于开采沉陷研究的必要性,重点介绍了关键层理论在开采沉陷研究(关键层对地表沉陷的影响、开采沉陷预计、采动地裂缝、地表减沉与采空区稳定性评价等)中的应用现状与进展.分析表明,将关键层理论应用于开采沉陷有助于研究地表沉陷动态过程与采动地裂缝形成机理,并提高沉陷预计精度及地表减沉效果.同时,还讨论了现有研究的不足,进而提出今后的研究方向与待解决的问题.

| Abstract: | The generation background,development process and application status of the key stratum（KS）theory were described,then the necessity of the application of KS theory in mining subsidence was analyzed.The Current status and progress on the application of KS theory in mining subsidence,such as the impact of KS on surface subsidence,subsidence prediction,mining-induced crack,surface subsidence reduction and goaf stability,were introduced in detail.The analysis indicates that it is helpful to study on dynamic process of surface subsidence formation mechanism of mining-induced crack,the accuracy of subsidence prediction and surface subsidence reduction effects may be improved in the application of KS theory in mining subsidence.The limitations of present literature were investigated,and the areas for further study in the future were proposed. |
