US miners attain record low fatality and injury rate in 2012

The US released preliminary 2012 data Tuesday indicating the lowest fatality and injury rates in the history of the country's mining sector.

The mine safety and health administration, part of the federal labour department, said in a written statement the action of both government and industry contributed to the reduced numbers.

In 2012, the fatality rate was .0107 deaths per 200,000 hours worked while reported injuries were 2.56 per 200,000 hours worked — lower than the prior year’s rates.
