By 1908, it was estimated that the total coal production of the county had exceeded 350,000 tons, despite the lack of any rail connections. Most of this was from the Carbon area. Coal from the Carbon mines was sold locally, with some sold as far away as Corning and other towns within a 25-mile radius. The two most notable mines in the area in 1908 were the Jones, Smith and Tindall mine, a new mine employing 25 miners, 1/4 mile south of Carbon and the J.F. Ruth mine, a year-old mine employing 30 miners, 1/2 mile northeast of town. Both used horse whims to power their hoists, and had minimal safety features. At the time, one other mine had recently been closed by a cave-in, and another was just being opened.
