West Bengal Agriculture minister and local MLA Malay Ghatak told PTI, the six were taken to nearby Kalla Hospital for medical check-up and they were fine.
The men, all local villagers, were trapped as the abandoned mine caved in last afternoon and were trapped underneath for over 30 hours.
Two Rescue Teams from Eastern Coalfields Ltd and the state worked in tandem for hours drilling a parallel to the abandoned mine and the six were taken out one by one at around 5-30 pm, Ghatak, camping at the site said.
The coal-rich area is dotted with illegal mines as a section of locals regularly extract the mineral for selling in open market.
The administration, in coordination with Eastern Coalfields Ltd (EC), sometimes undertake drive.
