On November 13, 1989, a catastrophic disaster struck the Mahabir Colliery in the Raniganj coalfields of West Bengal, India. What began as a routine day of extracting coal turned into a deadly race against time when a routine explosion accidentally breached an underground water table. Millions of gallons of water flooded the subterranean chambers, transforming the mine into a watery grave.

On the night of , 220 miners were completing their shifts at the Mahabir Colliery in the Raniganj area. Standard coal-wall blasting operations went catastrophically wrong when a detonation accidentally breached an upper water-bearing seam.

Gill realized that if they could not remove the water from the men, they had to remove the men from the water by drilling directly from the surface. He proposed a borehole capsule rescue method—a concept that had never been successfully executed in India under these conditions.
