Although the number of coal seams within the field is not 
large, yet the lateral extent is so great and the strata are, as a 
rule, lying at such low angles, that a very large amount of coal is 
available at a minimum depth. 
SingrauU. — The name of this coalfield is derived from that 
of a petty principality now absorbed in the Rewah State and the 
adjoining districts of the United Provinces. The first discovery was 
made in 1840 by Captain Wroughton^ and analyses of the coal 
gave only 2 per cent, of ash. The best-known locality was Kota, 
where four bands of coal aggregating 4 feet 9 inches in thickness 
are found in a total thickness of 6 feet 3 inches of strata. For 
some years mining was carried on, the coal being carried over bad 
roads, a distance of about 80 miles to Mirzapur, where it was 
sold for use on the Ganges steamers. 
In reporting on the coalfield in 1857, D. Smith^ refers to an 
outcrop of 9 feet of clean coal at Toorah, near Nowar Nagar, 
about 6 miles west of Kota. He also found coal being quarried 
in Rewah at Pudree, about 18 miles west of Kota, the seam being 
21 feet in thickness. 
In 1894-96 the area was geologically mapped by a party under 
R. D. Oldham ^ during the course of the season's operations in 
Rewah. The total area of Damudas is about 900 square miles. 
Coal seams were found in several localities, the thickest being near 
Ujeini and Amilia where thicknesses of 6 and 5^ feet, respectively,
