Acoustic Emission and Failure Modes for Coal-Rock Structure under Different Loading Rates

Acoustic Emission and Failure Modes for Coal-Rock Structure under Different Loading Rates

Coal bump refers to a sudden catastrophic failure of coal seam and usually causes serious damages to underground mining facilities and staff. Considering the combined coal-rock structure for coal bumps, failure process and acoustic emission (AE) characteristics of combined coal-sandstone samples und...
