MSHA Data File Downloads

Data files on mining accidents, injuries, fatalities, employment, production, etc., are collected by the Mine Safety and Health Administration (MSHA) under Part 50 of the U.S. Code of Federal Regulations (http://www.msha.gov/30cfr/50.0.htm). Original raw data files are released periodically to the public on the MSHA web site (http://www.msha.gov/STATS/PART50/p50y2k/p50y2k.htm. As a convenience, NIOSH has converted MSHA data from 1983 through 2009 to SPSS (which includes labels and coding information) and dBase IV file formats.

Several recoded and computed variables have been added to the information provided by MSHA. Beginning with the 2006 data, fatalities determined to be chargeable after the MSHA data files were closed out are added to the data files maintained by NIOSH. There was one chargeback fatality included in 2006, and an additional chargeback included in the 2007 data files. Because these data have been obtained from sources outside of NIOSH, they are provided on an "as-is" basis.
