Application of strain gauge and geophone based integrated monitoring system in the measurements of the blast induced low-frequency vibrations.

ABSTRACT: The paper presents an evaluation of the low-frequency blast-induced vibration and stress records generated by blasting operations in an open-pit mine. Measurements were conducted using an integrated 3-axial geophone and strain-gauge system. The third-octave analysis confirmed the low-frequency characteristic of the vibrations, within a frequency range of approximately 5-13 Hz. Time-domain analysis demonstrated a correlation between blast-induced vibration records and stress records. The energy of the stress and vibration records was determined using the Matching Pursuit algorithm. The analysis results indicated that blast-induced vibration and stress records were consistent not only in the time domain but also structurally; energy peaks in the analyzed records occurred simultaneously, rega
