The unmanned excavator technology was studied and applied in the construction of the inclined shaft for water diversion in the TB Hydropower Project for the first time. At the same time, through measures such as optimizing blasting parameters, strengthening the connection between processes, and improving blasting support time, the safety of construction was greatly improved, the construction progress was accelerated, the construction efficiency was increased, and the construction cost was reduced, creating considerable direct economic and social benefits, which can provide reference for inclined shaft excavation in similar hydropower projects.
