The Sound of Rockbursts: A new monitoring approach for longwall coal mines

  A rockburst is a phenomenon where rock or coal is violently ejected into mine openings. Rockbursts can release significant amounts of energy and have the potential to injure workers and disrupt operations. Despite decades of research, these events are notoriously difficult to predict, and focus has turned to managing the related risks. In hardrock mines, seismic monitoring – the same technology used to monitor earthquakes, has proven invaluable for understanding and managing rockburst-related hazards. Most deep hardrock mines have a seismic monitoring system. However, coal mines, specifically longwall mines, have struggled to apply these same systems. There are several
