Data & Statistics


The Data and Statistics pages provide analyzable data files and summary statistics for the U.S. mining industry. The information presented here is generated using employment, accident, and injury data collected by the Mine Safety and Health Administration (MSHA) under CFR 30 Part 50.

THIS JUST IN! The Mining Program recently released the new NIOSH Mine and Mine Worker Charts statistical resource. This dynamic tool provides interactive charts for the U.S. mining industry using data from years 2008 to 2017. Users can select a variety of breakdowns for statistics, including number of active mines in each sector by year; number of employees and employee hours worked by sector; fatality counts, rates, and accident class; and injury counts and rates by sector and accident class. NIOSH plans to replace other static charts on the website with these more dynamic charts.

Summary Statistics

Graphs, tables, and maps summarizing a variety of information are generated on a regular basis. The data are presented for mine operators as well as independent contractors working on mine property for the following mining sectors:

Economic Analyses

The  NIOSH Mining program has begun development on a suite of tools for assessing the economic cost of accidents and injuries. The goal is to illustrate how improving safety can help improve the bottom line.

The first of these tools is Safety Pays in Mining. This web application shows the cost of worker injuries and gives some suggestions for ways the savings might be reinvested.

Historical Mine Disasters

Historical Mine Disasters are incidents with 5 or more fatalities. Data tables (1839 through present) and graphs (1900  through 2016) by mining sector are provided.

Mining Fact Sheets

Mining Fact Sheets containing interesting facts, graphs, and data tables relating to mining operations, employees, fatalities, and nonfatal lost-time injuries. The format from 2000 through 2008 consisted of individual fact sheets for overall mining and each commodity.  From 2009 through 2017 the format changed to a single-web page with sections for overall mining and each of the major mining industry sectors.

MSHA Data Files

MSHA Data Files for mining accidents, injuries, fatalities, employment, production are available in SPSS and dBase IV formats. These files cover the period from 1983 through 2017.

Statistical Methodology

Description of the standard statistical methodology followed by the Surveillance and Statistics Team for the presentation of the MSHA data.
