ABSTRACT
There is considered the compliance of existing method of forecasting subsidence and deformation of earth surface to the real situation. There is developed and tested the mathematical model for forecasting subsidence and deformation of earth surface with taking into account the influence of mesorelief. Results of the model calculations are shown that errors of deformations caused by mesorelief may reach significant values, especially errors of relative deformations. These errors can significantly affect the accuracy of forecasting deformation of earth surface.
