Feds: Mine missed safety check before rock burst

A federal inspection report shows that officials at the Lucky Friday Mine in northern Idaho failed to conduct the second of two daily monitoring checks on the day a violent rock burst broke the pelvis of one miner and also injured six others. The report is part of a collection of more than 300 pages of inspection documents the Spokesman-Review obtained through a Freedom of Information Act request. In November, the Mine Safety and Health Administration ordered managers at the underground silver mine in Mullan to perform twice-daily monitoring of stress in rocks in mine shafts.
