The Kemmerer Coal Company's Sorensen Mine Operations

The Kemmerer Coal Company's Sorensen Mine is located approximately 7 miles Southwest of the Town of Kemmerer, Lincoln County, Wyoming. The coal it produces is delivered via conveyor directly to Utah Power and Light's Naughton Steam Generating Plant. The Plant went on the line in the spring of 1963 and the Sorensen Mine has been producing coal since February of that year. In this period, approximately 2, 000, 000 tons of coal have been delivered to the Plant. Present Sorensen mining operations are being carried out in the upper seams of the Adaville Formation. The formation contains, in some places, up to 30 coal seams of varying quality and thickness. Thirteen seams are considered major and are given numbers; the rest are considered splits off of the major seams and are so named. The lowest seam stratigraphically is the No. 1, or Elkol seam. So far, it has not been committed to power production but is being held in- reserve. It is the thickest seam with 80-90 feet of coal as its average thickness. The other major seams vary from 10-50 feet thick, with most of the seams averaging 17-26 feet of thickness. Each major seam has been opened at least once' to obtain a true gross sample of the coal's performance in the Plant.
