This boundaries of this coalfield are the boundaries of Buchanan County, Virginia, which is sandwiched between McDowell County, W.Va. and Pike County, Ky. in the heart of Appalachia. The National Coal Association and the Norfolk & Western Railway divided it into Upper Buchanan and Lower Buchanan Coal Districts, with Grundy being on the line of demarcation. The Upper District mined seams that were an extension of the neighboring Pocahontas Coalfield and also Virginia coal beds like the Lower Banner seam. The coals in the Lower District (Clintwood,Splash Dam, and Taggart / Darby seams) are also mined in nearby Big Stone Gap Coalfield. The county has no navigable rivers, and was served by the N&W (now N-S) Railway.
Buchanan Coal & Coke Company, and Sayers Pocahontas Coal Company began purchasing Buchanan properties in 1904 of "sufficient surface for making drift mouths, air shafts, wells, and sufficient land on which to erect tipples, tanks, pipelines, washers pumping stations, coke ovens, miners' houses, roads, railroads and sidings, tramroads, incline roads, chutes and such other devices as is necessary for the successful mining and manufacturing and removing said coal, oil, gas, fire clay, stone ..." Also at this time, Ritter Lumber Co. built narrow gauge railroads into Buchanan County to haul their lumber to market. Norfok & Western purchased these railroads, as well as the Big Sandy & Cumberland Railroad, in the 1920s and early '30s and began the process of converting them from narrow gauge to standard gauge in preparation for developing the coalfield. The Buchanan Coalfield started producing late - in 1932. One of the first operations was Home Creek Smokeless Coal Company. Other early operations included Lynn Camp Coal Corp., Buchanan County Coal Corp., and Sycamore Coal Corp.
Later in the 20th century, as the original coal veins became depleted or uneconomical, the coal companies sunk shafts down into the deeper Pocahotas No. 3 seam. This low volatile "smokeless" coal continues to be mined into the 21st century at Consol's Buchanan 1 mine near Raven, Va. As of 2024, this longwall mine is owned and operated by Coronado Global Resources.
