Research on calculation and prediction methods for surface subsidence in mined out areas
In this paper,the author takes the goaf area formed by a certain coal mine as the research area,on the basis of collecting coal seam occurrence and existing goafs distribution,selects the reasonable physical and mechanical indexes of rock layers,using the common probability integration method and numerical simulation method to predict the subsidence value,horizontal deformation and maximum surface vertical deformation,so as to predict the surface deformation in the study area.The prediction of surface deformation in coal mine goaf is an important basis for the prediction and evaluation of the suitability of engineering construction site.
