Icon of line chart
The NIOSH Mine and Mine Worker Charts are interactive graphs and tables for the U.S. mining industry that show data over multiple or single years. 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.

Summary Maps

Maps showing mine locations, employment by county, and fatal and lost-time injuries by county. Maps are available for the following industry sectors:

All Mining |Coal | Metal and Nonmetal | Stone and Sand & Gravel Industry Sector

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.

Background and Statistical Methodology

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, among other sources, and prepared by the NIOSH Mining Program following a standard statistical methodology.
