A section of the Telangana Srisailam Left Bank Canal (SLBC) tunnel collapsed trapping eight workers on February 22. Rescuers have recovered the first body, and work is on to find the others. Arnold Dix, 61, is International Tunnelling and Underground Space Association president (2022-25) He explains why building tunnels in young mountains like the Himalayas is trickier than in the older mountains of, say, Australia. Dix also spoke about the difference between the Indian Himalaya and the mountains on the Chinese side. He says India has 20 exciting years of building massive infrastructure projects including tunnels and underground rail connections ahead. He also explains why mountaineers have found the mountains near Mt. Everest to be almost fragile and very fragile. As a geologist or rock expert to see that this is a soft sedimentary rock that breaks off easily easily, is a very difficult thing to do. He concludes by saying, \”I’m telling you about the story because it reminds me of the rescue of the Silkyara tunnel\”
