Research On The Design Of Continuous Belt Conveyor For Long Distance Tunnel Mucking

With the rapid development of China's economy,there are many high-speed railway and water conservancy projects under construction,consequently we need to build more and more long-distance tunnels.In order to improve tunnel construction efficiency,new technology and equipments are badly needed.Tunnel mucking is one important problem,nowadays continuous belt conveyor system is the best choice.But the core technique of long-distance tunnel continuous belt conveyor is monopolized by few foreign manufacturers,there is no detailed design and research material at domestic.So it is very necessary to imply research on the design of long-distance continuous belt conveyor system.In this paper,firstly we determined the fundamental mucking scheme of continuous belt conveyor,then the basic parameters of the system as well as tape strength,intermediate driving position and tensioning force are fixed through theoretical calculation and research.The design of the key components are implemented through theoretical calculation and selection,we also use the 3D modeling by SoildWorks software and the finite element method by ANSYS Workbench software,so as to verify the rationality of the components' design.In this paper,the design method and the main points of continuous belt conveyor system are introduced,we hope it will be helpful for the design and improvement of this tunnel mucking system.
