Abstract: At present，most of the roadway are supported in symmetrical support methods.In view of this situation，the stress，deformation and failure characteristics of roadway surrounding rock were investigated through the theoretical analysis，numerical simulation and the physical analog simulation technique.The research indicated that the surrounding rocks of roadway driving along goaf in inclined seam appear as asymmetric state.The obtuse angle positions formed along the cross section of roadway and the rock strata dip are damaged and deformed firstly，and then with a chain reaction generated at other positions，the whole roadway is completely destroyed.Therefore，the conventional symmetric supporting technology can not guarantee the stability of surrounding rock of roadway.Aimed at the research result，the asymmetric support technology is recommended.On the basis of symmetrical support，the weak（key）positions are additionally supported to prevent the destruction of the whole roadway chain resulted from partial failure.It makes the whole cross section of roadway tend to be coordinated.Field tests on the ground pressure and the deformation of surrounding rock show that the equal stress of the bolt and the roadway deformation can meet the safety requirement.So the roadway supporting performs well and this supporting can be considered as a reference for similar roadway.
