| Abstract: | By using the principles of structure mechanics, material mechanics, the paper proved that the maximum moments appears in the crown and the abutment of combined arch. The caculation formula of the thickness of the load-bearing arch is deduced and on such a basis, a theoretical model for calculating bolt parameters is built in roadway excavated in instablc rocks. The model was a applied and verified in the bolt pattern design in the development tunnels in Donghai Coalmine. |
