APPLICATION OF AUDIO RECORDERS FOR REGISTERING SEISMIC SIGNALS FROM INDUCED SEISMICITY PRODUCED BY BLASTING IN OPEN PIT MINES

Abstract

Seismic events induced by blasting operations in open pit mines pose significant challenges for monitoring and mitigation. This paper presents an innovative approach utilizing audio field recorders to capture seismic signals from both vertical and horizontal geophones deployed in mining environments. Field experiments were conducted at a mining site, where a network of geophones coupled with audio recorders was strategically deployed to comprehensively monitor induced seismicity. The integration of audio field recorders with geophone arrays enabled the accurate detection and analysis of seismic activity, providing valuable insights into the spatial distribution and characteristics of induced seismic events. Our findings underscore the efficacy of audio field recorders in recording high-fidelity seismic data, showcasing their versatility as essential tools for seismic monitoring in challenging mining environments. Furthermore, this research contributes to enhancing safety protocols and risk management strategies in the mining industry by leveraging innovative technologies for improved seismic monitoring and mitigation efforts.
