Abstract：Base on the mining practice，supposing the overlying strata as a elastic slab，the tend towards main section plane prediction model，the incline main section plane prediction model and the ground full section subsidence prediction model with elastic slab theory. Result shows that the models have the same characters as other models，also they have are established the following characteristics：briefness，distinctness and easy use. The models overcome the demerit of symmetry about inflexion in the old models，and accord well with the mining practice. Finally，the applied effect of the models are proved with a practical engineering.
