ECL begins sealing Khandra Colliery after surface cracks near temple

Eastern Coalfields Limited (ECL) has initiated precautionary sealing of the Khandra Colliery in the Raniganj coal belt after surface cracks were detected near the Nikanth Temple in the area. The move, announced on Monday, is aimed at preventing any potential safety hazards.

The cracks and ground subsidence were first noticed on July 28 in a zone where several unauthorised structures and illegal occupants are present. ECL stated that these structures had previously restricted surface-filling work in the affected area, raising concerns about air ingress into underground workings and the possibility of aggravating spontaneous heating conditions.

Describing the action as a "preventive and proactive safety intervention," the company said the step was taken to safeguard employees and surrounding areas. ECL added that constant monitoring will continue to assess the situation.

Authorities have assured that there will be no disruption to the existing water and electricity supply to residential quarters due to these measures. Existing manpower will be suitably deployed either in another unit of the same mine or in neighbouring mines, as per operational requirements.

ECL has not specified how long the mine will remain sealed. The company refuted reports suggesting a three-month closure, stating that the duration has not been decided and will only be confirmed in accordance with expert advice, technical assessment, and established mine-safety practices.

The Raniganj belt is one of India's oldest and largest coal-producing regions, with operations dating back to before Independence. The area has a history of hazardous incidents, including a landslide in May 2026 at a mine in Jamuria that killed one worker and injured several others. Ground subsidence has also caused cracks in homes, leading many residents to abandon their houses and turning several villages into ghost towns.
