Application of MEMS-Based Accelerometers for Near-Field Monitoring of Blasting-Induced Seismicity

Proper monitoring of seismic risk and reliable evaluation destress blasting efficiency requires a well-developed network surrounding the analyzed area. Unfortunately, construction dense system using standard types seismometers accelerometers is associated with high costs development maintenance. Significant improvements in this regard may be potentially achieved by replacing expensive devices other cost-effective sensors such as MEMS-based accelerometers. Nevertheless, topic has not been sufficiently investigated yet, usefulness for seismicity deep underground mines recognized. The goal paper was to perform preliminary measurements blasting-induced near-wave field use single three-axial accelerometer three uniaxial seismometers. collected records induced multi-face were compared time frequency domains. In domain, values 3D peak motion plots analyzed, possibility identification subsequent delay times recorded waveforms investigated. case distribution, Power Spectrum Density calculated compared. results analysis proved that provide successfully implemented regular systems.
