Overview

History

The history of Jharia Coalfield was started since nineteenth century. The only   energy source during those years, the mining was carried out through manual and semi-manual methods resulting into large scale degradation of  land, forests and environment. The unscientific mining resulted into large scale mine-fires, subsidence and land degradation. The mines of Jharia Coalfields were taken over by BCCL from the erstwhile private mine owners. Most of the mines had their history from pre-nationalization period.

During the takeovers of the mines in 1972 in BCCL from private mine owners, the data like leasehold area, underground mine planning, production capacity was unknown. However, most of the mines were further re-organized.

Most of the mines are contiguous in nature and the environmental impact is overlapping in ambient environment due to cumulative effect of the mining activities.
