Abstract: Considering the problems and shortcomings of conventional mucking modes and conveyor equipment during tunnel construction, this paper puts forward a new mode of continuous-belt conveyor mucking suitable for D&B tunnels as well as various design and equipment selection options adapted to different types of tunnels. This new method is based on the analysis and comparison of mucking and conveying technologies among different tunnel construction methods as well as the study of continuous-belt mucking technology and its equipment. The study shows that more comprehensive benefits could be obtained by continuous-belt conveyor mucking technology than that of the conventional method in terms of technology and economy. Furthermore, it is an important way for continuous mucking technology to achieve the goals of low-carbon economy and environmental protection during tunnel construction, especially for extra-long or plateau tunnels.
