Rat-hole coal mine – Assam

January 17 , 2025 2 hrs 0 min 24 0
  • Recently some workers trapped and died in a flooded rat-hole coal mine at Dima Hasao district in Assam.
  • It is an unscientific and illegal form of mining prevalent in some parts of the North-East.
  • It is called the rat-hole mining because the tunnels are narrow and allow the movement of only one person.
  • The underground passages are interconnected but they become veritable traps for workers when the mines collapse or flood.
  • In 2014, the National Green Tribunal (NGT) banned rat-hole mining.
