ABSTRACT
The influence depth of the new building load in the strata above the goaf was calculated by using the foundation additional stress method. The building's foundation stability on the goaf was quantitatively evaluated, and the building height was determined. The residual subsidence deformation of the construction site was predicted, and the anti-deformation technical measures used to ensure building safety were put forward. The technical application and engineering practice were carried out at Pingdingshan mining district in Henan Province. The results show that it is feasible to evaluate the foundation stability on the goaf by comparing the bottom interface position of the influence depth of the new building load with the top interface of the mining fracture zone. It is very necessary to take anti deformation technical measures for resisting the residual deformation to ensure the new building safety.
