The world's largest humanitarian operation has been successfully completed

 A massive humanitarian operation that drew the world's attention ended in one night recently. The 17-day operation launched to save 41 lives that were facing death has now ended by ensuring the safety of all lives. They are all safe. We believe that this operation left a very special mark in the history of the world, which had to rely on human labor and experienced practice rather than advanced technical methods at the last critical moment. The Silkyara-Dandalgaon tunnel under construction on the Brahmakal-Yamunotri highway in Uttarkashi, Uttarkhand The Silkyara-Dandalgaon tunnel under construction on the Brahmakal-Yamunotri highway in Uttarkashi, Uttarkhand, India, collapsed on the 12th.

At the time of the landslide, a 2 km long tunnel had been excavated in that mountainous area. A team of 41 workers were working inside the 8.5 meter high tunnel. These 41 people were trapped in the tunnel with the massive landslide.

Now the first thing is to keep this group alive in this trapped trap. No idea how long the redemptions will take or what the plan is. But there was a definite identification of the underground area where the workers were working. First steps were taken to provide oxygenated ventilation into the trapped tunnel. It happened with the help of a pipe that was directed into the tunnel. Some communication could also be done through the tube.

Commencement of excavations

The planned excavation will begin two days after the accident. Horizontal drilling began with the help of drills with spiral steel spikes. By November 14, a supply line had been established that ensured a steady supply of essentials such as food, water and medicine for the trapped workers into the tunnel. Three days into the operation, the rescue teams realized that they were not satisfied with the feasibility of deploying the rig they had initially selected. The rescue teams immediately requested an advanced technical drilling rig from Delhi. The machine was brought by air to speed up operations.

By November 16, the assembly and installation of the new drilling rig began. Operations will begin in earnest after midnight on the 16th.

How the accident happened and the subway is raining...

Machine breakdown

Horizontal drilling along the covered tunnel mouth advanced rescue teams about 24 meters. But the effort stops there when the rig breaks down. But rescue teams immediately airlifted another high-performance drilling rig from Indore.

On November 17, the rescue teams had a shocking experience. By the afternoon of that day, a significant cracking sound had come out of the tunnel. A terrifying risk of 41 lives being buried alive in the tunnel was created. With this, the operation launched so far stopped for a while. Officials and experts from India's Prime Minister's Office (PMO) devised five new evacuation plans, exploring alternative methods such as vertical drilling to save the workers. Mining operations were suspended pending a scientific approach regarding a sustainable method.

Meanwhile, a specific effort to increase the morale of the people trapped in the tunnel had been launched with the people who were constantly talking to them. Meanwhile, the planners also started digging for an alternative tunnel parallel to the tunnel.

At that time, the workers were trapped in the tunnel, which was buried under a 12-meter large piece of debris. The place was at a depth of 48 meters in the surface hilly terrain.

The rescue teams' next approach was to access the tunnel by drilling vertically above the tunnel from the ground. But at a depth of about 45 meters, drilling was once again hampered by the tunnel's iron-clad wire rods. Even though the obstacles were removed and the workers reached the 48 meter limit, the drilling machine was once again interrupted. Vertical drilling stopped once again.

Handing over the work to human labor

By now, India had added the support of international tunnel experts to the rescue operation. Tunnel experts Arnold Dix and Chris Cooper headed the mission. He reported that the drilling rig used for the excavation had stopped working again. He suggested that the excavation of the final section should be done by expert human labor rather than leaving it to mechanical tools. On November 27, a team of 12 tunneling experts with special practice joined the operation. Hand excavation to remove the last 10 to 12 meters of debris began with their participation.

Similar to rat burrowing, tunneling is done by tunneling experts using hand-held tools in confined spaces. But the system was controversial amid accusations that it would encourage another group to take extreme risks and work underground.

However, the excavation work was carried out successfully. With 24 hours of continuous human labor, rescue teams inserted a pipe into the tunnel, which had been dug. The pipe extended through the tunnel for 57 meters. Last night at 7.56, the first employee left and came through that tube. The remaining 41 trapped workers have since emerged from the 17-day tunnel in good health. Along with the operation, it was planned to provide the necessary health facilities for the rescued workers. A special ward with 41 oxygen support beds was set up at the Community Health Center in Chinyalisore, about 30 km from Silkyara, to treat the rescued workers.

Until the people rescued from the tunnel came..

Medical staffs were prepared. Arrangements were made to transport employees to more advanced hospitals if necessary. However, yesterday we saw a wonderful sight. On one side of the world, when the skulls of the animals were blown up, the bombs were fired and the dogs were killed like crows, the true value of a human life was once again revealed to the world. I believe the world got that message from the Silkyara tunnel rescue mission.
