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. Original raw data files are released periodically to the public on the MSHA web site. As a convenience, NIOSH has converted MSHA data to SPSS (includes labels and coding information) and dBase IV file formats.
To reduce the file sizes, the ZIP file format has been used for data compression and storage. Although computer set-ups will vary, Microsoft has built-in zip support for the compressed folders. If you have the SPSS or dBase programs on your computer, you should be able to download the files by clicking on the link and selecting Open or Save. If you intend to use the dBase IV file with another application (i.e., Excel), you may find it best to save the compressed folder to your computer, open the folder and copy the file to your computer. You can then open the .dbf file with Excel.
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.
