Why it matters
It highlights ongoing safety and environmental challenges in aging industrial mining regions.
The Eastern Coalfields Limited (ECL) has begun sealing the Khandra Colliery in the Raniganj coal belt due to surface cracks. This comes as a precautionary measure after surface cracks were reported near the Nikanth Temple in the area, officials said on Monday (August 31, 2026).
The cracks and subsidence were first observed on July 28 in an area where several unauthorised structures and illegal occupants are present, according to ECL. The company said the structures had restricted surface-filling work in the affected area, raising concerns about air ingress into underground workings and the possibility of aggravation of spontaneous heating conditions.
“The measures have been initiated purely as a preventive and proactive safety intervention,” ECL said in a statement on Monday (August 31, 2026). They also said that this step was taken to safeguard their employees and the surrounding areas and they will continue constant monitoring to assess the situation.
