Bowie #2 Mine

Bowie #2 Mine

bowiemediumThe Bowie #2 mine is a longwall mining complex in Paonia, CO approximately 74 miles east of Grand Junction, CO. Bowie began production in 1998 and from 2000 through 2007, it ranked it #1 or #2 nationwide for efficient longwall production.

In 2009, Bowie was purchased by Cedars Energy, LLC, the majority owners of Bowie Resource Partners, LLC from the financially-troubled Energy Coal Resources, Inc. From 2008 through early 2010, Bowie mined in an area historically known to contain high levels of methane (the Northeast District). In the first quarter of 2010, the principals of Cedars discontinued operations in the Northeast District and invested $80 million to develop the remaining reserve (the Southwest District). The move to the Southwest District was completed and longwall operations resumed in June 2011.

The Bowie mine is located in the Somerset coalfield, which is in the Uinta coal-bearing region of Western Colorado. The coals in this area occur in the Bowie and Paonia Members of the Williams Fork Formation, which range in thickness from 25-30 feet. The high geothermal heat flow characteristic of this part of the region has increased the rank of much of the coal that occurs here.

Bowie has longwall and continuous miner reserves in the B Seam in which it is producing high-BTU, low-sulfur, compliance thermal coal.
