Analysis on monitoring precision and reliability of microseismic monitoring system

The paper introduced the application of ARAMIS M/E microseismic monitoring system of Poland on the rockburst prevention in Huafeng coal mine. The monitoring precision and reliability of microseismic monitoring system were analyzed by locating of mine earthquake event and shooting in fixed points. The application results showed that the location precision of this system is high in three-dimension, location error is less than 20m in plane and less than 15m in vertical direction, it reached the request of system location. The system can evaluate the criticality of rockburst in working face by use of monitoring data and the criticality of rockburst in everyday can be evaluated. It provides scientific basis for coal mine to forecast rockburst.
