After a harrowing 17-day ordeal, all 41 trapped workers in Uttarakhand’s Uttarkashi, within the Silkyara tunnel, have been successfully rescued.

Initially marred by challenges, the rescue operation found success only after the involvement of an international tunnel expert, Professor Arnold Dix, in the final critical phase of the mission.

Professor Dix, an Australian expert, is lauded for his instrumental role in the successful completion of the rescue operation, a mission that kept Uttarakhand authorities on high alert since the workers became trapped on November 12, 2023.

The rat-mining process

  • Dix and other engineers resorted to the rat-mining method, manual drilling, after the Augur machine failed.
  • A method commonly used in northeastern India, particularly Meghalaya, for coal extraction, proved effective.
  • Following partial machine drilling, the rest of the drilling was accomplished manually.
