| Abstract: | This paper briefly reviews the development process of structural theories of overlying strata in longwall faces, and introduces the main academic viewpoints and their new development of the plane structural models at each stage and mainly discusses the structural stability of overlying strata in longwall faces and the present research situation of structural theories of overlying strata of fully-mechanized sublevel caving mining. And finally, this paper puts forward the thrusts of future research of roof pressure including the problem of roof control in large area, for example, the dynamic relationship between the spatial structure and stress field of overlying strata due to mining and the problem of abnormal roof pressure control in longwall faces as the fully-mechanized sublevel caving mining is applied and the mining depth is increased. And the latest research achievements in these aspects are introduced. |
