Mining Publication: Analysis of Seismic Signatures from Gas and Dust Based Explosions at the Lake Lynn Experimental Mine
Original creation date: February 2008
Examination of seismic records during the time interval of the Sago Mine disaster in 2006 revealed a small amplitude signal possibly associated with an event in the mine. More needs to be understood about the seismicity from mine explosions in order to properly interpret critical seismic information. A seismic monitoring system located at NIOSH's Lake Lynn Experimental Mine has monitored experimental gas and dust based explosions and impact tests. The seismic signatures from these different events were analyzed using standard waveform analysis procedures. The magnitude of seismic energy during a gas and dust explosion was found to be more dependent on mine entry geometry and seal behavior rather than on the amount of explosive fuel present.
