| Abstract: | In view of the problems of large deformation and difficult support in the roadway under the condition of high stress and soft rock in Changcun Coal Mine,this paper analyzes the existing problems of the original support,puts forward the support scheme of strengthening two top angles and central support for the roof and strengthening the lower support for the roadway side,and optimizes the support parameters of the roadway.The results show that the optimized support parameters can effectively control the deformation of surrounding rock. |
