Methods and practice of blast-induced vibration monitoring

摘要

Regardless of the objective sought, the conclusions drawn from seismic monitoring can only be as good as the quality of the recorded data: the importance of properly capturing relevant raw vibrational information in the first place is thus absolutely crucial. The difficulty is that blast-induced vibration monitoring is site specific and that general formulas do not apply: every situation will correspond to a unique combination of objectives, ground conditions, blast design and explosive types, and will need to be monitored accordingly. To adequately acquire all the pertinent seismic information, a number of points must be successfully addressed, such as the choice of sensors, their location, number, orientation and anchoring, the transmission of the captured signals from these gauges to the recording equipment, and the choice and set-up of the data acquisition system.;It is the purpose of this thesis to address these questions in some detail, in an attempt to provide the reader with an understanding of how all the components involved in blast-induced vibration monitoring interact, and on how the choices made at each step can significantly affect overall results.
