A significant part of industrial hygiene research and development in the United States is directed towards mining. Most of this mining-related research is done by the U.S. Department of the Interior's Bureau of Mines, which receives funding for health and safety research amounting to $30 to $35 million annually. The work is primarily directed towards coal miners, who have traditionally suffered the highest fatality and accident frequency rates of any industry. Health problems are also no stranger to the miner. Coal worker's pneumoconiosis, or "black lung" disease, has exacted an unprecedented toll of tens of thousands of lives. Black lung compensation costs about $2 billion every year. Although much of the worst is behind us, the coal mine still leaves much to be desired when compared to the factory floor visited by the typical industrial hygienist. Some of the Bureau's research could be adapted by other industries. I have volunteered to contribute a little to the technology transfer process by highlighting some mining innovations in a series of columns for readers of Applied Industrial Hygiene. Each will deal with some successful mining development that may be of general interest.
