Cluster Analysis of Closely Spaced Mining Blasts as a Method of Event Location
The aim of this research was to characterize the high frequency content of noise and signals, and to develop methods of discrimination between mine blasts and other seismic sources using high frequency and seismic data. Two previous reports (Israelsson et al., 1990; and Israelsson and Carter, 1991)...
