• Description:
  A study of large seismic events at the Lucky Friday mine in northern Idaho, U.S.A., revealed that, despite apparent randomness, there were common characteristics that could be used to define five types of recurring events. These common characteristics included slipping geological structure, first-motion pattern and the location and intensity of damage resulting from the seismic events. In all these events damage was concentrated at intersections between slipping structures and mine openings. The study was based on information collected in the course of a long-standing rockburst research program conducted by the U.S. Bureau of Mines in cooperation with mines in the Coeur d'Alene mining district and regional universities. Data were collected on 39 seismic events having local magnitudes greater than 2.5 that occurred between 1989 and 1994. The study provides a foundation for the design of measures to reduce further the potential for damage arising from these events and to assess whether changes in mining activity aimed at reducing one type of rockburst will increase the incidence of other types.
