Abstract
Rock bursts have been a problem in the Coeur d'Alene Mining District of northern Idaho for nearly a century. For over 20 years, acoustic monitoring systems installed at the Galena Mine, Lucky Friday Mine, Star Mine, and Sunshine Mine have gathered data on rock bursts and microseismic events. Currently, three separate systems monitor seismicity and rock bursts at the Lucky Friday Mine. A microseismic system run by the mine provides event locations, a macroseismic system operated by the U.S. Bureau of Mines estimates event locations and saves full waveform files for seismic studies, and the North Idaho Seismic Network monitors rock bursts in the mine as well as seismic activity near the mine not covered by the other two systems. This paper is a review of the data acquisition and analysis methods and presents an example showing how the systems complement each other.
