A Research of Reinforcing Ingate in Shale-Laminated Sandstone

Abstract:

Article Preview

The auxiliary shaft ingate of Pengzhuang Coal Mine deformed greatly with large roof fallings. Through the analysis of destruction, the ingate reinforcement schema is put up according to the engineering consolidation experience and the advanced consolidation experience at home and abroad. On the completion of the ingate project, the surrounding rock mass is stable without apparent deformation. The two-side and roof deformations are 4mm and 5mm respectively according to the convergence deformation test, improving the integrity and bearing capacity of the shaft and pipelines effectively. Thus the deformation of the surrounding rock mass is under control, guaranteeing the long-term stability of the roadway.
