Abstract According to the defects in physical similar material simulation test that cant meet some engineering requirement，the NC mechanical simulation testing system for deformation simulating the evolution of rock structure movement was developed.The development principles，main structures and function characteristics are given detailedly in this paper. The system can easily be operated，and has characteristics such as high automation，stable testing process，convenient disassembly and installation，good repeatability，which have been proved through laboratory test. The NC mechanical simulation testing system is superior to similar material simulation experiment for its laying difficulty，molding technology and forming quality is difficult to control，the long test cycle，materials can't be used repetitively，and is easily affected by external factors. The NC testing system can show the space structure evolution process of the overlying strata by mining，the corresponding relation between strata fracture mutations and stress field，the law of elastic deformation energy accumulation and release above the coal pillar intuitively.

Key words： mining engineering similarity theory NC mechanical simulation testing system overburden structure motion abutment pressure
