China unveils “Xianglong,” described by multiple reports as the world’s first tunnel boring-and-blasting machine. The machine, named Xianglong, has a reported diameter of about 4.5 metres. According to statements cited by outlets, it is jointly developed by Tsinghua University and a subsidiary of the state-owned China Railway Group. Reports say the machine rolls off the production line in Wuhan, the capital of Hubei province, after being produced in accordance with a provincial government statement. The core feature highlighted across coverage is that Xianglong combines conventional tunnel excavation with an integrated drilling and blasting system. Instead of relying only on mechanical cutting, it uses mechanical excavation alongside drilling and blasting as part of the tunnelling process. Sources characterize this design as different from conventional tunnel boring machines by integrating drilling and blasting capabilities directly into the system, aiming to broaden how tunnel excavation is performed. Both outlets present the unveiling as a notable technological development, while citing the same general details about its developers and production location.
