Microseismic Source-Parameter Dataset for a Time-Delayed Floor Rockburst in a Deep TBM Tunnel

This dataset contains field-monitored microseismic source parameters associated with the development of a time-delayed floor rockburst in a deep tunnel excavated by a tunnel boring machine (TBM). The microseismic monitoring system continuously recorded rock-fracturing activities in the surrounding rock mass during tunnel excavation. After signal identification, event location, and source-parameter calculation, a catalog of valid microseismic events was obtained. The dataset provides the processed microseismic data used to investigate the temporal evolution of microseismic activity before, during, and after the time-delayed floor rockburst.
