RI 5016 Estimate Of Known Recoverable Reserves Of Coking Coal In Letcher County, Ky. ? Conclusions

1. The investigation shows that there are 2 coal beds of major importance in Letcher County from the standpoint of present production - Upper Elkhorn No, 3 and Fire Clay - and 5 beds of minor importance - Whitesburg, Flag, Haddix, Elkhorn Leader, and Amburgy, The Upper Elkhorn No. 3 and Fire Clay beds contain the largest remaining known reserves. 2. Known measured and indicated reserves in all beds, based on a minimum thickness of 14 inches and on 1,600 tons per acre-foot of coal in place, are estimated at 1,353 million short tons as of January 1, 1952. Of this total, 1,056 million short tons ere in beds 28 inches and more thick. Areas in each bed were omitted from the estimate because available data relative to the bad characteristics are too meager to make an estimate that conforms with the definitions of measured and indicated coal adopted for this study. Should future drilling or development prove reserves in these areas, such reserves should be added to the total estimated reserves.
