From page 27...
... Research is also needed in discrimination of seismic signals from mine blasts and ground failures from other seismic events. SY1\IPATHETIC DETONATIONS Sympathetic detonation of explosives is the unintended detonation of an explosive charge by the detonation of another explosive charge in the proximity.

... in addition, such research could provide important information for improving mine design and for developing warning systems prior to the occurrence of these failures. INSTRUMENTATION AND ANALYSIS OF GROUND MOTION WAVEFORM CHARACTERISTICS One area of research that could greatly benefit the mining industry is the development of affordable monitoring equipment with a higher resolution level

From page 29...
... DISCRIMINATION OF SEISMIC SIGNALS The availability of source infonnation from mining blasts in the United States would allow for the improvement of travel-time models and earthquake location algorithms. One goal of further work in this area would be the development of regional velocity models that could be used to greatly improve seismic event locations.
