| Abstract: | In order to ensure the stability of the soft surrounding rock in the air return roadway of 3209 working face,according to the specific characteristics of the roadway deformation,it is determined to adopt the technology of"strong side supporting roof"and high-strength anchor bolt supporting,combined with the characteristics of the roadway to design the supporting parameters.During the excavation,the integrity of the roadway roof is good,the main problem of large deformation of the surrounding rock is solved,and the stability of the soft surrounding rock is guaranteed. |
