Application of a convolutional neural network for seismic phase picking of mining-induced seismicity. [PDF]

Geophys J Int, 2021
SUMMARY Monitoring mining-induced seismicity (MIS) can help engineers understand the rock mass response to resource extraction. With a thorough understanding of ongoing geomechanical processes, engineers can operate mines, especially those mines with the propensity for rockbursting, more safely and efficiently.
