Abstract: Based on the analysis of the west main haulage roadway across the three coal-bearing geological conditions of Shunhe Coal Mine,and according to the released circle supporting theory,the supporting program of the roadway was determined.The joint-supporting of “anchoring-bolting-cable-shotcreting-grouting” means fully integrating the natural bearing structure of the surrounding rocks,and improves the integrity and carrying capacity of the supporting.Through monitoring and numerical simulation analysis,roadway deforms within its design limits.Engineering tests showed that the joint-supporting scheme has a good supporting effect.Compared with the shed supporting,it can lower the project costs,and speed up the construction progress.The scheme has certain value of popularization and application.
Key words: Soft rock roadway, Released circle, Support program, Joint Support
