1 Includes NEC(Assam grade) coal.
2 Includes semi-coking coal and weakly coking coal
A significant majority of our non-coking coal is produced by us from mines operated in the Korba, Singrauli, Talcher, IB Valley and Wardha Valley coalfields, which in the aggregate accounted for 68.7%, 69.5% and 70.7% of our total non-coking coal production in fiscal 2008, 2009 and 2010, respectively. Most of our coking (metallurgical) coal is produced at the Jharia coalfield.
