在国外煤矿开采中,自十九世纪初就开始对采场顶板岩层移动影响直至地表的移动理论进行初步研究.我国从上世纪90年代起也开始了“浅埋煤层岩层控制研究”,随着岩层控制方面研究的不断深入,产生了关键层理论.关键层理论是采场矿压、岩层移动和地表沉陷研究有机结合的纽带,在学术界和工程应用界得到了广泛的关注,尤其为浅埋煤层研究奠定了坚实的岩层控制理论基础.%It has made preliminary study on stope roof strata movement affecting until surface movement theory since early 19th century in foreign coal mining, and our country also started the "research of shallow buried coal seam strata control" from the 1990s. With the deepening of studying strata control, the key strata theory is emerged. The key strata theory is the link of the organic combination of research on mining pressure, strata movement and surface subsidence, which has been gotten extensive attention in academia and the engineering application circles, especially laid a solid strata control theory foundation for shallow buried coal seam research.
