RI 6487 Design Requirements for Instrumentation To Record Vibrations Produced

This paper presents arguments which show that a velocity seismograph should be used to measure building and ground vibrations produced by blasting . However , portable velocity seismographs suitable for this type of measurement are not commercially available . The paper describes how a velocity seismograph can be assembled from commercially available velocity gages , amplifiers , and recorders . Also , specifications are given which could be used in the design and manufacture of a portable velocity seismograph suitable for measuring vibrations from blasting .
