Introduction
At the Silkyara tunnel site, the rescue efforts encountered a setback as the auger machine became lodged in the debris. To keep the morale high among the 41 trapped workers, mobile phones and board games were provided as a source of encouragement throughout the last phase of the rescue operation.
Officials shared that the augering machine's blades got stuck in the rubble on Saturday, leading them to contemplate alternative strategies. The consideration of switching to other options raised concerns about potentially prolonging the rescue operation by several more weeks.
Amid these challenges, a decision was made to initiate manual drilling of the collapsed tunnel starting on Sunday. This shift in approach aims to overcome the obstacles posed by the stuck auger machine and advance the rescue mission. The provision of mobile phones and board games reflects an effort to alleviate the stress and anxiety of the trapped workers as they await their rescue.
Lt Gen (retd), a member of the National Disaster Management Authority, emphasized the unpredictable nature of operations in mountainous terrain, stating, "This operation could take a long time. When you are working on a mountain, everything is unpredictable. We never gave any timeline." The acknowledgment highlights the challenges posed by the mountainous environment, emphasizing the need for a flexible approach to the rescue operation without committing to a specific timeframe.

Professor Dix is a well-respected expert in tunnel safety and disaster response, currently serving as the President of International Tunnelling Underground Space. His experience and credentials speak volumes about his knowledge in this field. In the ongoing crisis, he plays a vital role.
How workers got trapped?
The workers have been trapped since November 12, when a landslide led to the collapse of a section of the 4.5-kilometer (2.8-mile) tunnel they were constructing. The incident occurred approximately 200 meters (650 feet) from the entrance.
Timeline of the Uttarkashi tunnel collapse and rescue operation:
November 12:
The multi-agency rescue operation commenced following the collapse of a section of the under-construction Silkyara tunnel on Uttarakhand’s Char Dham route. This incident trapped 41 workers, who are still inside.
November 13:
The rescuers achieved the first contact with the trapped workers by using a pipe designed for oxygen supply. Additionally, walkie-talkies were provided, and the workers were reported to be safe during this initial communication.
November 14:
An auger machine, specializing in horizontal drilling, is introduced to establish a pathway for pipes through the rubble. Workers receive supplies of food, water, and medicines during this phase.
November 15:
Due to issues with the regular auger machine, an American auger machine is requested. The situation prompts protests at the rescue site.
November 16:
Union Minister VK Singh pays a visit to the collapse site. To enhance the drilling capabilities, a more powerful American auger is brought in, facilitated by Indian Air Force aircraft, and it begins operations at the site.
November 17:
By the afternoon, the auger machine successfully drills about 24 meters through the 57-meter stretch of rubble. Another auger machine is airlifted from Madhya Pradesh to support the ongoing efforts.
November 18:
A high-level meeting at the Centre explores five rescue methods, including vertical and parallel drilling from different angles to reach the trapped workers. The brainstorming session aims to optimize the rescue strategy.
November 19:
Union Minister Nitin Gadkari oversees the rescue operation and expresses that, among the explored methods, drilling horizontally seems to be the most promising option for rescuing the 41 trapped workers. This assessment underscores the ongoing evaluation of strategies to ensure an effective and safe rescue.
November 20:
A significant development occurs as a six-inch lifeline pipe successfully penetrates the debris of the collapsed tunnel, marking the first major breakthrough. The trapped workers receive their first hot cooked meal, 'khichdi,' providing a vital morale boost.
November 21:
Groundbreaking visuals of the trapped workers emerge as an endoscopic camera is sent through a 6-inch pipeline. This technological advancement provides crucial insights into the condition of the workers.
November 22:
Authorities announce that the rescue operation is in its final stage, with ambulances and hospital beds placed on standby. This preparation indicates the anticipation of successfully concluding the rescue mission and transitioning to the medical care phase.
November 23:
November 24:
The rescue operations in Uttarkashi's Silkyara tunnel collapse experienced a pause on Friday due to another glitch encountered by the auger machine.
November 25:
Uttarakhand Chief Minister Pushkar Singh Dhami disclosed that the auger machine is stuck inside the tunnel. To resolve this issue, a specialized piece of equipment is being flown in from Hyderabad, indicating efforts to extract the machine and overcome the obstacle in the ongoing rescue operations.
