Using state-of-the-art blast monitoring equipment provides the capability for real time analysis of frequency and peak velocity data in the field. Data can be analyzed on site, using computer downloading or hard copy printouts. Through plots of frequency versus peak particle velocities on United States Bureau of Mines (USBM) and office of Surface Mining (OSM) graphs; contractors, concerned citizens and regulatory officials can work to develop a custom site specific blast monitoring program. Using the right equipment and a good monitoring program allows for a more informed decision making process for all parties involved.
