Eastern Jharia Area is one of the 12 operational areas of BCCL located in Dhanbad Sadar subdivision of Dhanbad district in the state of Jharkhand, India.

History
The Jharia coalfield is the only repository of coking coal in the country. Coking coal is being mined for over a century in the Eastern Jharia Area with such mines as Bhowrah, Sudamdih and Patherdih. Geo-mining conditions in the underground mines vary from moderate to extreme. In some cases, it is so extreme that these are amongst the most difficult mines to work in the world. This has resulted in the deeper seams, with good quality prime coking coal, to remain untapped. Moreover, shallow deposits worked by primitive methods, in pre-nationalisation period, is leading to mining fire.

It had an open cast section with a normative production capacity of 0.42 million tonnes per year, a peak production capacity of 0.546 million tonnes per year and an expected life of 4 years.

2.Bhowrah South colliery, with an underground mine, has a normative production capacity of 0.29 million tonnes per year and a peak production capacity of 0.377 million tonnes per year. It had an expected life of over 30 years. The 3 pit open cast section with a normative production capacity of 0.235 million tonnes per year, a peak production capacity of 0.305 million tonnes per year and an expected life of 4.5 years. The Chandan open cast section with a normative production capacity of 0.158 million tonnes per year, a peak production capacity of 0.205 million tonnes per year and an expected life of 2.5 years.

3.Patherdih colliery, with an underground mine, has a normative production capacity of 0.054 million tonnes per year and a peak production capacity of 0.07 million tonnes per year. It had an expected life of over 30 years. The Chandan open cast section with a normative production capacity of 0.22 million tonnes per year, a peak production capacity of 0.286 million tonnes per year and an expected life of 4 years.

4.Sudamdih Incline colliery, with an underground mine, has a normative production capacity of 0.09 million tonnes per year and a peak production capacity of 0.117 million tonnes per year. It had an expected life of over 30 years.

5.Sudamdih Shaft colliery, with an underground mine, has a normative production capacity of 0.185 million tonnes per year and a peak production capacity of 0.24 million tonnes per year. It had an expected life of over 30 years.

Mine fire and subsidence
In the Eastern Jharia Area about 17.85 hectare of surface area is affected by  mining fire and subsidence. At Sudamdih and Patherdih collieries, all the quarries affected by fire and subsidence have been filled up. Most of the affected area in Bhowrah (North) colliery has also been filled up with quarry overburden.

Healthcare
The Eastern Jharia Area has 3 hospitals – Jealgora Regional Hospital with 100 beds, Bhowrah Hospital with 10 beds and Sudamdih Hospital with 10 beds,
