CHAPTER IX. 
KOREAGARH COALFIELD. 
This, the third of the Korean coalfields, is the smallest, having 
an area of about G square miles.^ Lala Hira Lai who surveyed 
it made only a hurried examination and found no seams of any 
vahie. In a stream-bed on the south slope of Koreagarh Hill 
he found a section showing 29" coal in 4 seams in a total _ thickness 
of 7 '8" ; he also found a 6" band of coal near Dugidei 
Hill. Mr. Harris reports the location of three exposures with 
thicknesses varying from 3 to 5 feet, with intervening bands of 
stone. They occur in the Ganga Gauri Jharia, Sendha Am Jharia, 
and Bcla Jharia, respectively. The coal appears to be of medium 
quality. The manager of the Khargaon Zamindari, in a list of 
the known coal exposures in his zamindari, gives the following 
additional localities : — 
Koreagarh : — 
Mendabera Nala, Lanjhar Nala. 
Duggi :— 
Chatapani Naia, Malin Ghag, Kurlia Ghag, Bija 
Ghag, Damankund Ghag. 
I was unable to visit this field myself.
