Food, water, and lighting were lowered through the borehole immediately. This act alone restored hope among the trapped men. They were no longer alone in the dark.
: The air inside the closed cavern was running out, replaced by toxic gases.
The 1989 Raniganj coal mine rescue is celebrated as one of the world's most successful rescue operations. Led by engineer , the mission saved 65 miners trapped 330 feet underground at the Mahabir Colliery in West Bengal. The Incident (13 November 1989)
Gill quickly took charge of the situation. He assured the trapped miners that help had arrived and that they would all be rescued. He then began organizing the evacuation. Two men would go up in each trip; one would sit in the capsule, while the other would cling to a rope attached to the outside. Gill, showing immense composure and humanity, remained behind in the flooded mine, giving courage to the men as they waited for their turn. “You only get one life, you need to make it count…Everything happened so suddenly that no one had the time to think,” he would later recall. raniganj coal mine rescue full
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.
The area was no stranger to danger; an abandoned, water-filled mine from the British era lay adjacent to the active tunnels, a ticking time bomb that had been sealed off but not neutralized. Shortly before 4 a.m., one of the scheduled blasts cracked the wall separating the active mine from this old, water-logged shaft.
Gill immediately took command of the chaotic scene. He established order, evaluated the physical condition of each miner, and decided that the weakest and sickest men would be evacuated first. The One-by-One Evacuation Food, water, and lighting were lowered through the
While others saw only an impossible situation, Gill saw a way forward. He devised a plan to drill a new, wide borehole directly down to where the miners were trapped. Then, he would fabricate a narrow, specialized to be lowered through that hole, bringing the men to the surface one by one. [9†L27-L28] [11†L24-L26]
: A blast accidentally punctured an upper seam of an abandoned, water-filled pit, causing millions of gallons of water to rush into the lower levels.
The news of the accident sent shockwaves through the local community and the administration. Hundreds of anxious family members gathered at the pithead, their desperate faces illuminated by the glare of emergency lights. Authorities in West Bengal and Coal India officials immediately launched a massive rescue effort. Multiple teams were formed, and emergency protocols were set in motion. However, the initial attempts to save the miners were met with failure. Giant pumps were lowered into the mine to drain the water, but the influx was so enormous that officials estimated it would take at least 60 to 90 days to pump it dry—time the men did not have. The oxygen levels were dropping, and the structural integrity of the mine was becoming dangerously unstable, raising the risk of a complete collapse. : The air inside the closed cavern was
Gill proposed drilling a vertical borehole from the surface directly down to the chamber where the 65 miners were stranded. However, drilling a hole large enough to hoist a man to safety through shifting, unstable rock was fraught with massive structural and safety risks.
On the night of November 13, 1989, approximately 232 miners were working the night shift at the Mahabir Colliery in Raniganj, West Bengal. During routine excavation involving controlled explosions, an underground wall cracked, leading to a sudden and massive influx of water from an adjacent abandoned pit.
The remaining 65 miners managed to run to the highest elevated point of the pit (the "rise area"), completely cut off from the surface.
