With the expansion of our infrastructure and production technology continues to evolve , the problem of the shortage of land for construction have become increasingly prominent , land development and utilization of old goaf is very important for improving the utilization of mining land to ease the tensions of the mine land resources . Mine gob area foundation stability assessment study for the construction of buildings above the old goaf has far-reaching significance . Xuhuai Radio and Television Center construction site stability analysis , for example, from the theory and practice analysis the old foundation stability of the goaf research methods and measures to solve practical problems . Firstly, domestic and international old goaf stability of the status and trends of , and affect the of old goaf foundation stability of the various factors and Discussion , analysis of the the the red ore mine the geological conditions Xuhuai radio and television building underground mining situation. Papers on the construction site of surface subsidence in the status quo , the residual settlement planning mining subsidence expected , and numerical simulation to obtain the residual settlement and the role of different layers of the building under the conditions of the area under the additional stress transfer similar geological conditions mine gob area foundation stability evaluation of guiding significance . On this basis , Xuhuai Radio and Television Center Foundation made ​​a stability analysis , drawn in a stable stage area for the radio and television building , ground movement and deformation in the building allows the deformation within the conclusion of the old mining the empty area foundation treatment and the structure of the building measures resistance to deformation , and finally draw clear conclusions and recommendations of the construction of the selected address .
