Advances in Monitoring of Mining-Induced Seismicity, Data Processing and Interpretation for Safe Underground Mines

Seismicity induced by mining accounts for ~37% of all human-induced earthquakes and is responsible for one of the strongest and most destructive anthropogenic earthquakes such as the magnitude 5.2 earthquake in the Klerksdorp mining district (South Africa) and magnitude 5.4 event in the Ernst Thaelmann Potash Mine (Germany) or the tragic collapses that occurred in Crandall Canyon Mine (Utah, USA) and Rudna Copper Mine (Poland). It is a well-known phenomenon, that has been long studied. Its understanding and study requires joint efforts of seismologists, rock mechanics, geologists, and mining engineers. Mining-induced seismicity is an important factor that has to be taken into account in rock stability in the underground mines and some deep open-pit mines. This factor increases with the mining depth as more and more of the induced seismic events, even small ones, can cause damage in the underground infrastructure (rockfalls and rock bursts) and in some cases casualties.Studies of seismic events in mines are usually based on records from underground local seismic networks run by the mining industry, often with additional data from surface seismic systems to monitor the vibrations on the ground and/or regional seismic stations. Very advanced geophysical techniques are used now for processing the data and obtaining the seismic source parameters. Sophisticated studies of time-dependent seismic hazards are underway. Seismic monitoring in the mines is an important and mandatory t...
