SUGGESTED METHOD FOR BLAST VIBRATION MONITORING

This guideline is separated into three main sections. The first section, Character of Blast Excitation, defines the terminology necessary to describe blasting vibrations and the associated air over pressure. Importance of dominant frequencies of excitation and structural response is introduced here and is emphasized throughout the document. The second section, Measurement Techniques and Instrumentation, describes generic attributes of instruments necessary to measure time histories of the blast- induced disturbances. Special emphasis is placed on computerized systems. Guidance is given for the choice and deployment of instruments, both at the beginning and continuation of a project. The third section, Evaluation of Measurements, presents definitions of structural response. Explanation is given for the need of studies with immediate pre- and post-blast inspection to separate weather- and blast-induced response. Guidance is also given for monitoring response of rock masses and buried structures. (A)
