There are fourteen coalfields in this group, namely Korar, Umaria, Johilla(Nowrozabad), Sohagpur, Sonhat, Jhilimili, Chirimiri, Sendurgarh, Koreagarh, Damhamunda, Panchbahini, Hasdeo-Arand, Lakhanpur and Bishrampur.

The group covers an area of about 5,345 square kilometres (2,064 sq mi) with estimated reserves of 15,613.98 million tonnes.

Therefore, extraction is mainly amenable to underground mining except a few blocks in eastern part of these coalfields which have opencast potential.

[3][4][5] According to Geological Survey of India reserves of non-coking coal up to a depth of 300 m in Umaria Coalfield was 181.29 million tonnes.

[9] The 161 miles (259 km) Bilaspur-Umaria branch line was opened in 1891, linking the entire area to the GIPR system at Katni.
