Based on the geologic and mining conditions,the surface movement and deformation along expressway were predicted,values of surface movement and deformation were obtained,and then the mining damages of the expressway due to coal mining were analyzed and evaluated.

The rule of surface movement and deformation for deep mining is much different from the one of mining under ordinary geological conditions.

Simulation on dynamic movement and deformation laws of buildings in mining area;

Algorithm of ground movement and deformation prediction in mining of random shape face;

Numerical simulation of the effect of thickness mining and loose seam s thickness on ground movement and deformation in mining subsidence;

Numerical simulation of stress distribution and displacement of rock strata of coal mines by means of DDA method;

This article mainly discusses the process of surveying surface three-dimension on similitude simulation test on mining subsidence indoor,the surveying data can be translated by visual program,surface displacement and deformation can be resulted by its relation,it resolves the difficult problem of how to survey the surface displacement and deformation on similitude simulation test.

Referring to the geological and mining conditions, and according to the mechanism of strata and displacement, the factors affecting the displacement and deformation, and the relationship between forwarding of working face and ground deformati.
