Abstract:
After long term and intensive mining of underground coal resources,large areas of coal mining subsid⁃ence have been formed on the ground,leading to serious economic,social,ecological,and environmental problems.The comprehensive management of coal mining subsidence areas is not only a major national strategic requirement but also a necessary path for the transformation and high⁃quality development of mining cities.With the acceleration of ur⁃banization,the demand for building utilization in subsidence areas is increasing,especially for the utilization of large buildings in coal mining subsidence areas in the suburbs of mining cities,higher requirements have been put forward for understanding the long⁃term state and evolution mechanism of mining strata,developing mining tratum govern⁃ance technologies and establishing scientific and reasonable utilization models.Scientific researchers have conduc⁃ted theoretical and technological research in the relevant fields of building utilization in coal mining subsidence areas,and countries around the world have also carried out engineering practices for building utilization in coal mining sub⁃sidence areas.First elaborates on the theoretical and technical system of building utilization in coal mining subsidence areas,then summarizes the research progress in four aspects those closely related to building utilization in subsidence areas:mining strata damage and long⁃term evolution laws,the interaction between buildings(structures)and mining strata,mining strata treatment and building deformation resistance technology and building utilization models in coal mining subsidence areas,and conducted an analysis of the current situation.It introduces the construction and uti⁃lization project in the coal mining subsidence area of representative areas such as Ruhr District in Germany,Huaihe River in Anhui,Jinan in Shandong and Tangshan in Hebei Province,demonstrates the necessity and feasibility of building utilization in the coal mining subsidence area for high⁃quality and sustainable development of mining cities.This paper prospects the development trends of building utilization in coal mining subsidence areas from three aspects:basic theory of building utilization in coal mining subsidence areas,scientific management and building utiliza⁃tion technology in coal mining subsidence areas,and large⁃scale building utilization models in coal mining subsidence areas.This paper systematically elaborates on the theoretical,technical,and engineering practice research status of building utilization in coal mining subsidence areas,providing direction reference for the research on building utilization in coal mining subsidence areas.
