UNIX Workstation Monitoring System for Coal-Bump Research

摘要

The U.S. Bureau of Mines has developed a monitoring system that acquires andanalyzes data for use in determining conditions that may precede mountain bumps in coal mines. Based on a UNIX workstation linked to an array of geophones in a working longwall operation, the system captures complete waveforms of microseismic events and simultaneously obtains continuous samples of the voltage levels of each geophone. Event rates and locations are calculated and displayed in real time on the UNIX workstation, which is situated in an underground instrumentation room.
