Study on Practical Application and Adaptability of the Roadheader in Transportation Tunnelling

The roadheader has been more and more used in the transportation tunnelling, but there are still many questions regarding its construction efficiency and adaptability in tunnels with different section sizes, geological conditions, etc. Accordingly, in combination with related project cases, this paper analyzes the construction efficiency and energy consumption issues in the construction of metro and railway tunnels with different section sizes and different geological conditions using the roadheader, comprehensively compares and analyzes its main performances and adaptability, and puts forward suggestions regarding the roadheader application scope, type selection, main operating performance and other aspects.
