Access a broad range of mine safety and health data including information about mine inspections, accidents, injuries, illnesses, violations, employment, production totals, air sampling, and more. Use our compliance calculator tools to find a mine’s history of key health and safety violations.
Mine Data Retrieval System (MDRS)
The MDRS gathers current and historical data from several MSHA databases and provides mine-by-mine data for all coal and metal/nonmetal mines and contractors in the United States, Puerto Rico, and the Virgin Islands.
Find a mine’s history of key health and safety violations
Over the years, MSHA has studied its data to determine the common causes of injuries, illnesses, and fatalities. It is evident that the violations of a small number of health and safety standards are responsible for the majority of fatalities and serious injuries and illnesses. MSHA has focused enforcement efforts on these key standards through a series of initiatives. The following online tools will allow anyone to monitor a mine’s compliance with these critical standards. The tools search MSHA’s database for a mine’s recent history of citations and orders in the following four groupings:
Significant and Substantial (S&S) Rate Calculator
An S&S designation indicates that the underlying safety or health hazard is likely to result in a serious injury or illness. This tool shows the rate of S&S citations and orders per 100 inspection hours during a certain time period.
Pattern of Violations (POV)
It is the responsibility of mine operators to track their violation and injury histories to determine whether they need to take action to avoid triggering a POV notice. Operators can determine whether they may be subject to a POV notice by using the POV monitoring tool, which is updated monthly.
MSHA provides text delimited data sets as part of the Open Government Initiative. Datasets cover a wide array of topics including accident and injury data, air sampling data, employment data, and many others.
Part 50 Data
Part 50 of Title 30 of the Code of Federal Regulation (30 CFR Part 50) requires mine operators to immediately notify MSHA of accidents, requires operators to investigate accidents, and restricts disturbance of accident related areas. This part also requires operators to file reports with MSHA pertaining to accidents, occupational injuries and occupational illnesses, as well as employment and coal production data. The data collected via Part 50 can be accessed at the links below.
- Part 50 Self-Extracting Files
These files contain the raw data collected from MSHA Form 7000-1 (Mine Accident, Injury and Illness Report).
- Part 50 SPSS and dBase IV Files
The National Institute for Occupational Safety and Health (NIOSH) has converted the data collected under 30 CFR Part 50 into SPSS and dBase IV file formats for ease of use in these two popular programs.
Department of Labor Enforcement Data 2.5
Access, search and visualize MSHA enforcement data using an interactive interface. Enforcement Data 2.5 contains data related to accidents, inspections, violations, and penalties, in addition to employment and production data.
The U.S. Government’s open data home page contains thousands of data sets on a broad array of topics.
