Two parallel-air injection tunnels
INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
ACCIONA's project consists of two parallel-air injection tunnels 4,375 m and 4,320 m long respectively, which form part of a group of five ventilation tunnels that will serve the Chuquicamata underground mine.
The tunnels, excavated by drilling and blasting, will have a section 10.74 m wide and 8.00 m high, with slopes of -14.47% and -14.79% respectively. Perpendicular to them, and to the three future injection tunnels, three galleries 7.75 m wide and 5.6 m high will be built, which will connect all of these tunnels.
The objective of the Chuquicamata Underground Mine Project (UCHMP) is to increase exploitation of the largest copper mine in the world until the year 2060.
- Location: Chuquicamata, Chile.
- Contract type: Construction and operation.
- Infrastructure: Tunnel 1 will be 4,375 m long and Tunnel 2 will be 4,320 m long. The tunnels will be joined by three 3 connection passages.
- Year of project completion: 2060
