| 【文章摘要】 The U.S. Department of Labor announced that its Mine Safety and Health Administration (MSHA) completed impact inspections at 16 mines in May, issuing 279 violations and one safeguard. MSHA conducts impact inspections at mines that merit increased agency attention and enforcement due to poor compliance history; previous accidents, injuries and illnesses; and other compliance concerns. The agency began impact inspections after an April 2010 explosion in West Virginia at the Upper Big Branch Mine killed 29 miners. |
