| Abstract: | In order to solve the support problems of the mine large cross section space crossing roadways with a closed distance,the FLAC3D numerical simulation software was applied to analyze the stress distribution features of the mine space crossing roadways and the stress increased and decreased zones formed along the axial direction of the below roadway.In comparison with the support effects of the different support plans in the stress increased zone,the support plan of the mine final space crossing roadways was ... |
| Keywords: | mine space crossing roadways anchor truss numerical simulation stress distribution support |
