American Consolidated Natural Resources

In August 2007 six miners were trapped at the Crandall Canyon Mine in Utah, of which Murray Energy's independent operating subsidiary UtahAmerican Energy had been a part-owner for 12 months. Prior to the collapse, the Crandall Canyon Mine had received 64 violations and $12,000 in fines.[13][14][15] At the time, Murray Energy's owner, Robert, claimed that the safety violations were trivial and included violations such as not having enough toilet paper in the restroom.[13] However, some news agencies reported troubling violations at other Murray operations. CNN specifically cited Murray's Illinois Galatia mine, which had almost 3,500 safety citations in the prior two and a half years.[16]

On July 24, 2008, the U.S. government's Mine Safety and Health Administration (MSHA) announced its highest penalty for coal mine safety violations, $1.85 million, for the collapse. The government fined Genwal Resources $1.34 million "for violations that directly contributed to the deaths of six miners last year," plus nearly $300,000 for other violations. The government also levied a $220,000 fine against a mining consultant, Agapito Associates, "for faulty analysis of the mine's design."[17]

Following the Crandall Canyon tragedy, the Mine Safety and Health Administration also was faulted by its parent agency, the U.S. Department of Labor, both for lax oversight before the collapse and for its handling of a haphazard rescue effort that left three more people dead.[18] An independent review of MSHA's role in Crandall Canyon by retired MSHA managers Earnest Teaster and Joseph Pavlovich, found that the agency failed to properly consider bounce activity in the mine prior to approving the mining plan, failed to properly evaluate the roof control plan and failed to follow established mine rescue protocols at all times at Crandall Canyon Mine. Specifically, the authors wrote that, "MSHA's failure to adequately evaluate the roof control plans contributed to the August 6 accident."[19] An independent review of MSHA's actions at Crandall Canyon also faults the agency for failing to control access to the mine, concluding that "MSHA improperly allowed media representatives and family members to enter the rescue area, and allowed an unlimited number of persons underground during the rescue operation."[19]

Murray Energy announced in October 2019 that the company was filing for Chapter 11 bankruptcy, and that Robert Murray would step down as CEO, but remain with the company as chairman of their board.[4] Murray was to be replaced by his nephew Robert Moore, formerly of Murray Energy subsidiary Foresight Energy, which is not part of the bankruptcy.[4][12] Murray Energy emerged from bankruptcy on September 16, 2020, selling almost all of its assets to a new holding company, now owned by its former creditors: American Consolidated Natural Resources Inc.[1][20] Robert Murray was Chairman of the Board of Directors for the new company until his death in October 2020.[1]

The bankruptcy filing revealed that funding had been given by the company to a number of organisations that promote climate change denial. These include the Committee for a Constructive Tomorrow, the Center for the Study of Carbon Dioxide and Global Change, the International Climate Science Coalition, the Heartland Institute, and the Competitive Enterprise Institute.[21]
