The Mine Safety and Health Administration has determined that a June 6 death at a Virginia surface mine was due to natural causes and therefore not chargeable as one of the fatal accidents at a US coal mine in 2011. Because of this action, the total number of coal mine deaths in the US so far this year stands at 13 rather than 14, according to MSHA records. The federal agency posted the change on September 21 on its website.
