Enter , a 50-year-old Assistant Chief Mining Engineer at Coal India. While officials debated bureaucratic protocols, Gill studied the mine’s blueprints and proposed a radical solution: build a makeshift steel capsule to lift the men out through a narrow borehole. raniganj coal mine rescue full

Once the capsule reached the gallery floor, the miners were instructed to enter one by one. The capsule would then be hoisted back to the surface. November 13, 1989 Location: Chora Colliery, Raniganj, West
As the water levels continued to rise, Gill coordinated the drilling of a narrow, 22-inch diameter hole—just wide enough for a human body. While the drilling rig groaned overhead, Gill worked with local fabricators to weld a steel capsule. It was a simple, narrow cage with a single oxygen tank and a door that opened from the inside.
Raniganj, India’s oldest coalfield, is a landscape scarred by a century of extraction. The geology is unpredictable—layers of coal interleaved with sandstone and aquifers. The disaster began innocuously: a 6-inch diameter borewell, drilled from the surface to map methane pockets, accidentally punctured an abandoned, water-filled working. Gravity took over. Millions of gallons of water, sediment, and debris cascaded into the active No. 3 incline seam, where 65 workers were extracting coal by the traditional "board and pillar" method.
