| dc.description.abstract | Most popular means of excavation for horizontal drivages/tunneling is drilling and blasting. In an attempt to get longer pull, higher explosive per hole is used resulting blast-induced rock damage (BIRD). The present existing damage assessment technique is based on peak particle velocity (PPV). Geophone used for PPV measurement has an range upto 254 mm/s which is unable to measure in the near-field. Far-field measured PPV when extrapolated may not be able to determine damage threshold level accurately. Acceleration measurement in the near-field is possible with the presently available accelerometers and damage threshold level can be determined with a better accuracy. | en |
