SOMERSET, Colo., March 22, 2012 /PRNewswire/ -- Arch Coal, Inc.

The Colorado Division of Reclamation, Mining and Safety presented the 2011 Excellence in Safety Award to West Elk mine, the state's leader in safety among large underground coal mines.  West Elk's rate of 1.70 MSHA total incidents per 200,000 employee-hours was 68 percent lower than the national underground average of 5.28 incidents.  This marks the third consecutive year that West Elk has been recognized as Colorado's safest underground coal mine.

West Elk also was recognized by the Colorado Division of Reclamation, Mining and Safety (CDRMS) for its environmental practices associated with its new $27 million coal preparation plant.  West Elk's award-winning practices include limiting construction to existing disturbed areas, reducing coal refuse generation and improving resource recovery.

In addition, the CDRMS recognized Ark Land Company with an Excellence in Reclamation award for its outstanding treatment of U.S. Bureau of Land Management lands during exploration and subsequent reclamation, including replacing native boulders and vegetation and re-grading former access roads on rugged terrain.
