Mine crews recently completed permanently sealing a mined-out area where increased levels of carbon monoxide were detected on April 29. However the situation has been resolved with technical support and assistance from the Mine Safety and Health Administration (MSHA).
Dugout Canyon mine and its 275 employees produced approximately 200,000 tons of low-sulfur bituminous coal per month in the first quarter of 2010, which equates to about 2% of Arch’s total production.
St. Louis-based Arch Coal supplies cleaner-burning, low-sulfur coal to fuel roughly 8% of the nation’s electricity. The company also ships coal to domestic and international steel manufacturers as well as international power producers.
