The Microseismic Source Analysis Of Real-time Signal In The Underground Mining

In order to promise going on wheels of mining production of WISCO Jinshandian ironmine,preventing hazardous accidents effectively by massive landslide during the miningprocess,Wuhan University of Science and Technology aiming at mining area has gone on withreal-time online microseismic monitoring.To monitor jinshan store Zhang Fushan iron oremining seismic event, is one of the effective methods to prevent incidents. Research groupdesigns suitable microseismic monitoring and positioning system for Zhang Fushan miningarea,gain improper microseismic wave form through collecting and analyzing microseismicsignal.Last make use of fast convergence Newton iteration method to back-calculatemicroseismic source coordinate and conduct a preliminary classification.It’s good for forecastingcalamity type and taking measures further to proceed a targeted prevention and control.Based onthe geological data and laboratory analysis results,research group decide to layout sensor at-340m.According to microseismic data analysis and mining area actual situation to conductmicroseismic events monitoring research and scientific evaluation about mining influence.Andoffering suitable advice about further production. Being in safe condition,we should recoverprecious mineral resource farthest.This research is very important for insuring the safety ofproduction,guiding further production and mining production decision-making.
