The Rawhide Mine is a coal mine located 10 miles (16.1 km) north of Gillette, Wyoming in the United States in the coal-rich Powder River Basin. The mine is an open pit mine that utilizes a combination of cast blast/dozer push and truck/shovel mining methods to strip an average of 165 feet (50.3m) of overburden off of approximately 105 (32.0m) feet of coal. Rawhide produces a low-sulfur, sub-bituminous coal from the Roland and Smith seams. This coal is used for domestic energy generation and shipped to customers via railroad. The mine is currently owned and operated by Peabody Energy.[1]
As of 2009, Rawhide had reserves of 388,000,000 tons (352,000,000 tonnes) of sub-bituminous coal and a maximum permitted production capacity of 24,000,000 tons per year. Typical annual production has been in 12–18 mm ton range for the last several years though. In 2010, the mine produced just over 11,225,000 million short tons of coal, making it the 13th-largest producer of coal in the United States.[2]
The average quality of the coal shipped from Rawhide is 8,300 BTU/lb, 0.37% sulfur, 5.40% ash, and 1.60% sodium (of the ash).
Train loading at the Rawhide mine is done in two passes. The first pass flood-loads the majority of the coal into the rail car while it is under the mine's silos, while a second pass tops off the car to its final target weight ± 250 lbs.
