He suggested drilling a new borehole and using a specially designed steel capsule to pull the miners out one by one. Despite the immense personal risk, Gill volunteered to go down in the capsule himself to organize the evacuation from inside the mine. The Operation: "Capsule Gill"
The stands as the most successful and dramatic underground survival operation in the history of Indian mining. Executed at the Mahabir Colliery in Raniganj, West Bengal , this historic operation saw the miraculous extraction of 65 miners trapped 330 feet below the ground inside a rapidly flooding pit. Led by the fearless mining engineer Jaswant Singh Gill , the rescue popularized the revolutionary "steel capsule" technique and fundamentally altered mine safety protocols across India. The Incident: How the Mahabir Colliery Flooded
Standard rescue methods, such as using pumps to drain the water, failed because the water level was rising too quickly. Jaswant Singh Gill devised an innovative, "non-conventional" plan:
In 1991, the President of India awarded Gill India’s highest civilian award for bravery in saving lives. He was the first living recipient of this prestigious honor.

I will follow the search plan as outlined. search results provide several promising sources. I will open the most relevant ones to gather detailed information. search results provide a wealth of information. I will now write a long article covering the full story of the Raniganj coal mine rescue. The article will have multiple sections, as outlined in the user's request. Raniganj coal mine rescue stands as a monumental chapter in industrial safety history, a real-life story of extraordinary courage and ingenuity that unfolded deep beneath the earth’s surface in 1989. It is a tale of survival against impossible odds and the unwavering spirit of a single man who refused to leave his fellow workers behind, an event so remarkable that it has since been immortalized in the 2023 Bollywood film, Mission Raniganj .
The idea was audacious and risky, but it was the only viable option left. Gill himself decided he would be the one to descend, refusing to ask anyone else to take a risk he was not willing to take himself.
: 232 workers were underground when the flooding started.
Jaswant Singh Gill's act of valor did not go unrecognized. For his unmatched bravery and ingenuity, he was awarded the , India's highest civilian gallantry award for meritorious acts of courage, by the then President of India, Ramaswamy Venkataraman, in 1991.

Shekhawat’s breakthrough was a leap of lateral thinking. Instead of widening the borehole (which risked collapse), he decided to use it as a conduit for a custom-made rescue capsule. The capsule would be a steel cylinder, just under 6 inches in diameter, with a hinged lid, a small oxygen cylinder, and a rope harness. A miner would have to strip naked, coat himself in grease, and squeeze into the tube headfirst, arms pinned to his sides, breathing through a small snorkel-like tube. The capsule would then be winched up through the borewell—a journey of 110 feet through jagged rock, groundwater seepage, and the constant threat of snagging.
The mine’s single shaft was completely submerged. Pumping out the water would take days, perhaps weeks. Drilling a new vertical shaft from the surface, through unstable overburden, could take even longer. Meanwhile, carbon dioxide and methane levels inside the trapped pocket were rising. The miners had already begun to suffer from hypoxia, thirst, and the creeping panic of claustrophobia.
The remaining 65 miners managed to run to the highest elevated point of the pit (the "rise area"), completely cut off from the surface.
When the operation concluded, a crowd of over who had gathered to watch erupted in jubilation. Gill was lifted onto their shoulders and carried in a hero's triumph. [11†L37-L38] [18†L26-L33] Executed at the Mahabir Colliery in Raniganj, West
While conducting routine blasts to crack open coal walls, the workers accidentally punctured an underground water pocket. This pocket was part of an abandoned, flooded mine layer directly above them.
Using old mine maps, the engineering team had to calculate the exact surface coordinates directly above the elevated gallery where the miners were presumed to be huddled.
