| Abstract: | The overlying strata of the coal bed roof are dominated by sedimentary rocks such as shale,sand stone and limestone,whose physical and mechanic properties differ greatly.This paper was designed to grope for the deformation rules of the overlying strata after exploitation with the method of model test,to provide a basis for the estimation of the stability of the mined areas. |

| Keywords: | Overlying strata Subsidence Similarity theory Mined areas Stability |
