| Abstract: | Based on the experiences and achievements in the roadways retained along gobedge at home and abroad, the paper researches on two questions mainly: the rational support and the defence by unloading of roadways retained along gobedge.The formula of calculation of support system resistance and yieldability under condition of medium stable roof is derived and proved through eguivalent model testing.The unloading in the roadways is studied by means of non-linear finite element method and eguivalent model testing |

| Keywords: | roadway retained along gobedge support in roadway support beside roadway defence of roadway by unloading |
