| Abstract: | The paper researches into the filled body’s deformation safety problem of technology of GERTCF under long time force, with the background of 3# coal bed of the S2-6 fully-mechanized coal winning working face in Changcun coal mine, considered the creep behavior of the material. The numerical calculation is used to analyze the deformation of the filled body within 3 years under the different sizes and different side pressures. The result of the material properties available can help to get the optimized range of the filled body designing. |
