Umaria Coalfield

Umaria Coalfield is located in Umaria district in the Indianstate of Madhya Pradesh in the valley of the Umrer River, a tributary of the Son River.

In 1886, W.W. Hunter wrote, “Extensive coalfields have recently been discovered at Umaria, within the native state of Rewa…”^[1]

Umaria Coalfield, which was owned by Rewa Coalfields Limited, was nationalized in 1973.

Umaria Coalfield is a part of Central India Coalfields. The latter is spread over the districts of Surguja, Koriya (both in Chhattisgarh), Shahdol and Umaria (both in Madhya Pradesh). 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. 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.^[2]

In Umaria Coalfield, the Lower Gondwana rocks are well developed. The coalfield has an estimated reserve of 181.29 million tonnes, spread across six coal seams. The coals are relatively high in moisture (7-10%) and high in ash (18.6-29.4%). South Eastern Coalfields Limited operates eight mines.^[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.^[6] Kanchan Open Cast Mine is being expanded from 0.32 million tonnes per annum to 0.65 million tonnes per annum, with a peak capacity of 0.75 million tonnes per annum. The entire overburden would be backfilled. There is 4 km metalled road connecting the mine to Vindhya Mine and onwards to Nowrozabad Railway siding.^[7]
