| Abstract: | Surrounding rock properties and failure mechanism of Guanlingshan,supporting parameters can be determined through theoretical analysis.With using UDEC numerical simulation software,the failure deformation conditions and stress distribution of roadway surrounding rock under different supporting parameters should be analyzed so as to optimize the supporting parameters of the roadway,then the roadway optimal supporting scheme and supporting parameter will be selected. |
