Preliminary data from the U.S. Department of Labor's Mine Safety and Health Administration (MSHA) show that mine fatalities in 2008 fell to an all-time low, recording a 31-percent drop from 2007.

Metal/nonmetal mines recorded the lowest level of fatalities in that sector of mining since statistics were first recorded in 1910, and the fatality level in coal mines was the lowest recorded number since 2005.

"Although these numbers demonstrate continuing improvements at our nation's mines, they also represent significant loss to the families and friends of 51 miners," said Richard E. Stickler, acting assistant secretary of labor for mine safety and health.

Of the 51 fatalities reported, 28 of the victims were at surface operations, while 23 miners died in underground mining accidents. Fifteen workers died in accidents involving powered haulage — ten in coal mines and five in metal/nonmetal mines — which was the leading cause of fatal mining accidents in the U.S. during 2008.

In 2008, MSHA assessed 198,700 civil penalties for violations of mine safety and health legal requirements, compared with 130,100 in 2007. The dollar amount of assessed penalties more than doubled in that time frame, from $74.5 million in 2007 to $194 million in 2008. The number and dollar amounts of civil penalties in 2008 are the most ever assessed in a single year.

Seventy-four flagrant violations were assessed in 2008, compared with 15 in 2007. They were assessed at a total for each year of $11,474,400 and $2,588,200, respectively.
