摘要

Drill and blast excavation is making steady progress in the early phase of underground works on the Cheves hydropower project, under construction in the Andes mountains of Peru. The contractor, Hochtief, leading JV Constructora Cheves, has excavated the adits and access tunnels at key areas of the 9.7km-long headrace, including the surge tunnel, the powerhouse where the crown has already been opened up. It is blasting from the lower section of the 3.3km-long tailrace as well as both ends of the transfer conduit between reservoir high in the catchment area.
