The coal roof of an abandoned mining patch of a BCCL outsourced company in Katras collapsed on Monday injuring four miners.
The miners were rescued by their family members and admitted to different private hospitals.
The incident took place three days after a crater developed in the backyard of a government primary school in Kuhunka village of Nirsa allegedly due to illegal mining.
Rajkumar Das, a local resident, said, “Though more than 50 persons were working at the site when a coal heap suddenly collapsed, six were buried of which four were injured but were taken out from the rubbles by other co-workers and their family members.”
