Mines and projects
Amlo Open Cast Project has an annual capacity of 3.0 million tonnes per year.[2]
Selected Dhori Group of Mines: The mine is operational and proposed for production capacity expansion from 2.25 million tonnes per year to 8.25 million tonnes per year (nominal) and 11.0 million tonnes per year (peak).[3]
Dhori colliery accident
One of the biggest disasters in the history of coal mining took place at Dhori colliery at about 1 AM on 28 May 1965. The death of 268 persons in the accident is the highest number of deaths in an explosion in India.[4]
Dhori colliery in the East Bokaro Coalfield was owned, at the time of accident, by Bokaro and Ramgarh Limited. Amlo, Upper Kargali, Lower Kargali, Bermo and Karo group of seams (including Phusro seam) were present in Dhori colliery. At the time of accident, only the Bermo seam was being worked. Although the Upper Kargali seam was known to be a gassy seam, the colliery as a whole was treated as non-gassy. Hurricane lanterns were used in the mine and it did not have any mechanical ventilation.[4]
There were alternative theories about the cause of the accident. The Court of Enquiry accepted the proposition that the accident was caused by the entry of a coal miner carrying a lantern into a gassy zone. The management theory of a sabotage was not accepted by the court. The observations and strictures of the Court of Enquiry lead to long standing changes in mining practices that have made mines safer.[4]
