For years, mine operators, federal and state mine safety agencies, and researchers have looked at numerous aspects of mine emergency response. Since the beginning of 2006, three major incidents occurred at underground coal mines in the United States, resulting in worker fatalities. These incidents raised a number of issues about mine emergency response including miners’ ability to identify and follow designated escapeways.
As part of a research effort to assess the effectiveness of evacuation training for miners, investigators have been assessing various technologies to guide miners through smoke-filled mine escapeways. These technologies include directional lifelines, strobe lights, high-intensity LED lights, and LED flares. Directional lifelines proved to be the highest rated escapeway guidance technology. Lifelines are now required to be installed in escapeways in all underground coal mines. Strobe lights and LED lights were also highly rated by miners who evaluated these technologies in dense smoke. Further research is planned to 1) make these lighting devices intrinsically safe for use in escapeways, and 2) integrate them into the larger mine emergency warning system to permit remote activation in an emergency.
