1970 - 1971 Mine Development
1971 - 2009 Coal Production Years 
2009 - 2017 Reclamation Work
Arch Mineral operated four surface mines in Hanna from 1971 through 2009. The Arch mines in total produced 83,448,830 tons of coal. During the company's forty years, it experienced no work related fatalities.

The Arch Seminoe No. 1 open pit mine started coal production in 1972. The mine produced coal for thirteen consecutive years. The mine was abandoned in 1984. The Seminoe No. 1 mine produced 24,210,781 tons of coal with a peak work force of 235 employees in 1979. No miners were killed at the Seminoe No. 1 mine.

The Arch Seminoe No. 2 open pit mine produced coal from 1972 through 1989. It was idle for 5 years from 1990 through 1994. Coal production resumed in 1995 through 2004. The mine was in production for 28 years. The mine entered reclamation work in 2005 and completed the job in 2015. The mine was engaged in reclamation work in Hanna for 11 years. Over its 44-year lifetime, the mine produced 35,478,877 tons of coal with a peak work force in 1979 of 325 workers. The mine experienced no work related deaths.

Arch gained control of the Medicine Bow surface mine from the Medicine Bow Coal Company in 1988 and operated the mine 19 years from 1988 through 2006. During that time the mine produced 23,124,569 tons of coal with peak employees in 1993 of 97 workers. There was no work related deaths at the mine.

Arch's Elk Mountain Mine, a surface coal mine, started coal production in 2007.  It was the last producing coal mine in Hanna. It opened in 2007 and closed production in 2012. Elk Mountain's coal was "loaded out" at the Arch Seminoe 2 facility. During the mine's last year in production it produced only 786 tons of coal. The mine produced 634,603 tons of coal over its lifetime. At the peak of production it employed 17 workers. Since closing production in 2012, the mine has been engaged in reclamation. As of December 31, 2015 Arch of Wyoming still had employees in Hanna. During the year the company was working to reclaim the Elk Mountain Mine and the Seminoe 2 Mines.
