History.
Tata Iron and Steel Company initiated prospecting of coal but no mining was carried out by them. The Chirimiri colliery was opened in 1930 (production started in 1932), New Chirimiri colliery came up in 1942, Pure Chirimiri colliery in 1945, and North Chirimiri colliery in 1946. Subsequently, New Chirimiri Pondi Hills, West Chirimiri, Duman Hill and Korea collieries started operating. Coal production rose from 264,000 tonnes in 1933 to 3,162,500 tonnes in 1980.
The collieries in Chirimiri Coalfield were owned by several companies and owners such as Chirimiri Colliery Company Pvt.

The group covers an area of about with estimated reserves of 15,613.98 million tonnes. The deposits are at a depth of 0–1200 meters. Therefore, extraction is mainly amenable to underground mining except a few blocks in eastern part of these coalfields which have opencast potential.
