الوصف: Some mining areas in China are facing with technical problems about coal mining under high-rise structures. The high-rise structure in the mining area is characterized by large height, small cross-section area, high center of gravity, small bottom area of supporting foundation, etc. It is a kind of special structure and is sensitive to the surface movement and deformation caused by underground mining. Based on the analysis of the characteristics of high-rise structures and their mining deformation characteristics, this paper summarizes and analyzes the research and development process of mining damage and protection technology of high-rise structures based on four aspects: mining deformation theory, numerical simulation, deformation monitoring technology, and protection technology, including the theory of cooperative deformation of high-rise structures and foundations, numerical (physical) simulation analysis of the impact of mining on the deformation of high-rise structures, real time, efficient and accurate monitoring technology, precise grouting and reinforcement technology for foundations, anti-deformation transformation technology for foundation, dynamic inclination adjustment technology for high-rise structures, reducing surface subsidence from the source, etc; The four development directions of mining damage and protection technology for high-rise structures are prospected: mining deformation characteristics of high-rise structures under the action of multiple indicators of surface movement and deformation, transmission mechanism from mining subsidence to deformation of high-rise structures, real-time and efficient accurate deformation monitoring technology for high-rise structures, and accurate protection technology for high-rise structures.
