| Abstract: | Based on the analysis of the stress distribution law in different districts around the self closed and full connected arch walling support roadway,the relationship among the limit equilibrium radius and the in situ rock stress,the physico mechanical properties and support parameters is obtained.The calculation formula of arch walling width design is put forward so as to provide a theoretical basis for the practical design of support. |
