NTT remote mining at Codelco’s El Teniente: design and risk notes for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Japanese telecommunications firm NTT Docomo Business is testing its IOWN All-Photonics Network at Codelco’s El Teniente, linking the underground mine to a remote operations centre in Rancagua about 1,500 km away to run heavy equipment and high-definition video over a high-capacity, low-latency optical network. The ministry-backed proof of concept targets remote operation, consolidation of control rooms and reduced underground exposure amid Codelco’s heightened focus on seismic risk after deeper Andes Norte studies revealed higher-than-expected hazards. If performance is proven, NTT plans to roll out IOWN-based remote operation models to other mining and energy projects globally.
Technical Brief
- NTT Docomo Business is trialling its IOWN All-Photonics Network (APN) specifically for heavy equipment teleoperation.
- The proof-of-concept is commissioned and funded under Japan’s Ministry of Internal Affairs and Communications.
- Management is explicitly targeting reduced underground exposure amid shortages of skilled equipment operators willing to work at depth.
- NTT plans to port validated IOWN APN safety/remote-operation configurations to other mining and energy assets worldwide.
Our Take
Our recent coverage shows Codelco simultaneously pausing deep expansion at the Andes Norte section of El Teniente for up to two years over seismic concerns, so NTT Docomo Business’ remote‑operation work is likely being evaluated as part of a broader risk‑management rethink rather than a stand‑alone tech trial.
With copper prices in our database hovering near record levels and tight physical supply repeatedly highlighted, any successful remote mining deployment at El Teniente in Chile could help Codelco stabilise output without pushing workers further into the higher‑risk deep zones flagged in July’s seismic studies.
Japan’s involvement via NTT and the Ministry of Internal Affairs and Communications aligns with other critical‑minerals security moves in our coverage, suggesting Tokyo is using remote‑operation know‑how at overseas copper assets like El Teniente to secure influence over upstream supply without direct ownership stakes.
