The results of a congressional investigation say sthat the general manager and possibly other senior staff at the Crandall Canyon Mine near Huntington, Utah, where 9 miners died in August 2007, hid information from federal mining officials that could have prevented the disaster and should face criminal charges. The report also said that the mining company should never have submitted a request to remove coal from the section of mine where the collapse occurred, and that federal mining officials should not have approved the proposal, because of foreseeable dangers.
