摘　　要：针对综放沿空留巷技术中的充填体长时受力变形稳定问题,以常村煤矿S2-6综放工作面主采3#煤层为背景,考虑材料的蠕变性能,运用数值模拟方法对不同尺寸和不同侧压下的充填体在3年内的变形情况进行了分析,得到了充填体安全工作条件下充填体材料必须具备的力学性能参数,为优化充填体材料设计提供了依据。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.
