摘要

Arch Coal Inc. on June 22 suspended production at its Dugout Canyon operation for the nsecond time in less than two months after discovering evidence of a possible "heating nevent" inside the Utah underground mine. nCanyon Fuel Co. LLC, the Arch subsidiary that operates Dugout Canyon, voluntarily nevacuated the mine on the morning of June 22, Arch spokeswoman Kim Link said June n23. Link did not elaborate on the reasons for the closure, but various media reports nindicate that the closure occurred after workers found possible signs of a heating event nin a section of the mine previously excavated by the mine's longwall. nAfter the mine evacuation, Canyon Fuel notified the U.S. Mine Safety and Health nAdministration of the incident, Link said. MSHA spokeswoman Amy Louviere nconfirmed June 23 that an agency inspector issued a closure order for the mine that will nremain in place until the underground problems are resolved. Link added that mine npersonnel continue to monitor the situation in an effort to determine what steps the ncompany will take next.
