Abstract:

Belt conveyer muckingout technology is investigated in the paper in order to solve the muckingout problem of long inclined shafts of long tunnels and to improve the muckingout efficiency in long inclined shafts. The comparison between the traditional muckingout methods and the belt conveyor muckingout method demonstrates that the belt conveyor muckingout method has various advantages. Several muckingout options are proposed on basis of the actual conditions of Guanjiao tunnel. Discussion is made on the muck transfer, muck storage, muck feeding and muck crushing at the bottom of the inclined shaft in case of belt conveying muckingout method. Finally, reasonable, economic, reliable and feasible muckingout method is determined. The paper can provide reference for similar projects in the future.
